The PosiTector 200 powers-up when the center navigation button is pressed. To preserve battery life, the Gage powers down after approximately 5 minutes of no activity. All settings are retained.
- Remove the protective rubber cap from the probe.
- Power-up the Gage by pressing the center navigation button.
- Zero the probe.
- Adjust to a known thickness, if necessary.
- Measure the part.
PosiTector 200 gages ship with a protective plastic cap over the probe. Remove this cap prior to use. Replace it when the Gage is not in use to protect the probe.
We recommend attaching and wearing the supplied wrist strap.
Plastic Lens Shield
The LCD is covered with a thin plastic film for protection against fingerprints and other marks during shipment. This film, while usually removed before using the Gage, can be left in place to protect against paint overspray or debris. Replacements can be purchased.
Couplant is required to propagate ultrasound into the coating. Water is a good couplant for smooth coatings. Use the supplied glycol gel for rougher coatings. While it is unlikely that the couplant will damage the finish or leave a stain on the surface, we suggest testing the surface by using the couplant on a sample. If testing indicates that staining has occurred, a small amount of water can be used instead of couplant. Consult the Material Safety Data Sheet and your coating supplier if you suspect the couplant may damage the coating. Other liquids such as liquid soap may also be used.
DeFelsko recommends that customers establish calibration intervals based upon their own experience and work environment. Based on our product knowledge, data and customer feedback, a one year calibration interval from either the date of calibration, date of purchase, or date of receipt is a typical starting point.
To disconnect a probe from a body, power-down the Gage and slide the plastic probe connector horizontally (in the direction of the arrow) away from the body. Reverse these steps to attach a new probe.
When powered-up the PosiTector automatically determines what type of probe is attached and does a self-check.
PosiTector 200 probes are available for measuring a wide variety of coating thickness applications.
- B probe:
13 to 1000 microns (0.5 to 40 mils) Ideal for polymer coatings on wood, plastic, composites, etc.
- C probe:
50 to 3800 microns (2 to 150 mils) Ideal for thicker coatings on concrete, fiberglass,etc.
- D probe:
50 to 7600 microns (2 to 300 mils) Ideal for thick, soft coatings such as asphaltic neoprene, very thick polymers, polyurea, etc. (50 to 5000 microns (2 to 200 mils) Polyurea measuring range)
NOTE:Range limits apply to polymer coatings only.
Additionally, the PosiTector accepts a number of probe types including magnetic and eddy current coating thickness, surface profile, environmental and ultrasonic wall thickness probes. Perform the latest software Updates to ensure probe compatibility with your Gage. For the latest information on probe interchangeability see www.defelsko.com/probes
PosiTector body accepts all 200, 6000, SPG, RTR, DPM and UTG probes.
Ultrasonic Thickness Theory of Operation
The PosiTector 200 probe emits a high frequency sound pulse that travels into the coating via a coupling gel and reflects from ANY surface that is different in density. Coating thickness readings are obtained by measuring the time taken for the ultrasonic signal to propagate from the probe to the coating/substrate interface and back. The travel time is divided by two and multiplied by the velocity of sound in the coating to obtain the thickness of the coating.
- Remove the protective rubber cap from probe.
- Power-up Gage by pressing the center navigation button.
- Apply couplant to the surface of the part.
- Lift the probe when you hear a double BEEP, - OR - leave probe on the surface in the same location for continuous measurements.
- When completely finished, wipe the probe clean of couplant then return the Gage to the protective pouch. There is no need to disconnect the probe from the PosiTector during storage.
Three steps ensure best accuracy...
- Calibration - typically done by the manufacturer. All probes include a Certificate of Calibration.
- Verification of Accuracy - typically done by the user on known reference standards such as plastic shims or coated thickness standards.
- Adjustment - to a known thickness
Calibration is the high-level, controlled and documented process of measuring traceable calibration standards over the full operating range of the probe, and verifying that the results are within the stated accuracy of the probe. Calibrations are performed by the manufacturer, their authorized agent, or by an accredited calibration laboratory in a controlled environment using a documented process.
Verification is an accuracy check performed by the user on known reference standards. A successful verification requires the Gage to read within the combined accuracy of the probe and the reference standards.
Adjustment, or Cal Adjustment, is the physical act of aligning the probe’s thickness readings to match those of a known thickness sample (removal of bias) in order to improve the accuracy of the probe on a specific coating. See Thickness
Gage functions are menu controlled. To access the Menu, pwoer-up the Gage, then press the center navigation button.
Below is a sample menu for a PosiTector 200 Advanced model:
NOTE:The center button is purposely recessed to help eliminate unintentional powering-up of the Gage.
PosiTector 200 probes must be periodically zeroed using the ZERO menu option to compensate for both extreme temperature and probe wear effects. Before using, allow the probe to reach ambient temperature. The icon appears after a Cal Reset.
If measurements will be made in extreme hot or cold temperatures, it is recommended to ZERO the probe in the working environment. If measurements will be made on rough substrates, it is recommended to periodically ZERO the probe to compensate for wear.
- Make sure the Gage is on and the probe is wiped clean.
- Hold probe in air away from the substrate.
- Select the Zero menu option.
- When complete, Gage will double beep and display "----".
The measuring range of each probe can be changed depending on the specific application or the expected thickness range of the coating system.
For most applications, the default range values do not have to be adjusted. But some conditions, like surface roughness, may cause the Gage to display very low or non-repeatable readings. In this case, the low range may be increased to cause the Gage to only display readings above the Lo value set by the user.
To adjust Set Range values...
- Select or with the Up and Down buttons.
- Use the (-)(+) buttons to decrease/increase the displayed value.
The PosiTector 200 interprets the largest “echo” or “echoes” within the selected range as the coating/coating or coating/substrate echo. If the coating thickness is outside this range, incorrect or dashed readings may occur.
Here are some typical Range settings...
|Expected paint thickness||Lo Range||Hi Range|
|500µm (20 mils) on concrete||130µm (5 mils)||1000µm (40 mils)|
|50µm (2 mils) on wood||25µm (1 mil)||250µm (10 mils)|
The PosiTector 200 measures most polymer coatings accurately out-of-box with no adjustment required.
To determine if an adjustment is necessary, select a coating sample of known thickness as close as possible in composition to the intended application. For best results, the thickness of the sample should be equal to or slightly greater than the maximum expected thickness of the coating to be measured.
Measure the coated sample. If the average of a series of measurements on the sample is not close to the known thickness...
- Select the Thickness menu option.
- Use (-) or (+) to decrease/increase the displayed measurement thickness value to match the known thickness of the sample.
- For Advanced models with multiple layers selected, use the Down navigation button to select the next layer and adjust as necessary.
- To save adjustments, use Down navigation button to highlight OK and press the center navigation button.
(PosiTector 200 D probes only)
When checked, the Gage loads a pre-programmed calibration adjustment optimized for measurement of polyurea coatings. “Polyurea” will appear on the upper right corner of the display.
NOTE: D Probe Measuring Range: 2 - 200 mils (50 - 5000 um)
When checked, the icon appears and the current calibration settings are “locked” to prevent further user adjustments.
Restores the Gage back to factory calibration and range settings. The icon will appear on the display.
Reset (soft reset) restores factory settings and returns the instrument to a known condition. The following occurs:
- All batches, stored measurements, images, batch names and screen captures are erased.
- All calibration and range adjustments are cleared and returned to the Gage's factory settings.
- The icon will appear on the display.
- Menu settings are returned to the following:
|Memory = OFF||Bluetooth = OFF||Layers = 1|
|Graphics = ON||Display = None||Layer Name = Layer 1|
|Cal Lock = OFF||Layer Color = blue|
Perform a more thorough Hard Reset by powering down the Gage, waiting several seconds, then simultaneously holding both the center and (+) buttons until the Reset symbol appears. This returns the instrument to a known, “out-of-the-box” condition. It performs the same function as a menu Reset with the addition of:
- Bluetooth Pairing info is cleared
- Menu settings are returned to the following:
|Units = microns||Battery Type = Alkaline|
|Flip Display = Normal||Backlight = Normal|
|Language = English||USB Drive = ON|
|Polyurea = OFF||Auto Sync = OFF|
Note: Date, Time and WiFi settings are not affected by either Reset.
For security purposes, the registration key is required to add the Gage to your PosiSoft.net account.
(Advanced models only)
When selected, the Gage displays a graphical representation of the ultrasonic pulse as it travels through the coating system.
As the probe is depressed and the ultrasonic pulse travels through the coating system, the pulse encounters changes in density at the interfaces between coating layers and between the coating and the substrate.
These interfaces are depicted by a "peak". The greater the change in density, the higher the peak. The more gradual the change in density, the greater the width of the peak. For example, two coating layers made of essentially the same material and "blended" would result in a low, wide peak. Two materials of very different density and a well-defined interface would result in a high, narrow peak.
The PosiTector 200 chooses the highest peak (single layer) or peaks (multi-layer) within the Set Range. For example, if the number of layers is set to 3, the three highest peaks would be identified with small red triangles. The peak values are also displayed numerically as thickness measurements.
NOTE: The Graphics display can also be accessed using the Set Range menu option
Use the navigation Up (move left) and Down (move right) buttons to highlight icons on the graphic display.
Zoom - Visually magnifies the waveform of the displayed peaks for more visibility. Pressing the (-) or (+) button repeatedly will increase/decrease the zoom.
Set Range - Press the (-) or (+) buttons to adjust the Gage’s Lo or Hi measuring range.
Screen Capture - Press to capture and save an image copy of the current display. The last 10 screen captures are stored in memory and can be accessed when connected to a computer. See Screen Capture and PosiSoft USB Drive. SHORTCUT: Press and hold the (-)(+) buttons simultaneously to capture any screen.
Menu - Press to access the Gage’s main menu.
Exit - Press to close the Graphics display. Press the Up button to return to the Graphics display.

The PosiTector 200 uses an ultrasonic principle to measure coating thickness of most coatings on most substrates. An ultrasonic signal is a very high frequency sound wave. Like the echoes you hear when you shout in a large hall or canyon the PosiTector 200 listens for echoes from acoustic boundaries within your application.
The PosiTector 200 probe emits a high frequency sound pulse that travels into the coating via a coupling gel and reflects from ANY surface that is different in density. Coating thickness readings are obtained by measuring the time taken for the ultrasonic signal to propagate from the probe to the coating/substrate interface and back. The travel time is divided by two and multiplied by the velocity of sound in the coating to obtain the thickness of the coating. The strength of the reflected signal from the coating/substrate interface determines the ability of the Gage to measure the thickness of the coating. Since most applications are not homogeneous the Gage will "hear" many echoes when placed on a coating/substrate. The Gage "hears" ALL reflections within the measurement limits of the Gage and assumes the largest “echo” is the coating/substrate echo (single coating applications only). Adjustable measurement Ranges have been provided for the user to force the Gage to ignore echoes from unwanted boundaries within the sample. Several examples below help to illustrate the use of the Set Range feature for specific applications.
When rough coatings are measured, the Gage typically identifies the thickness from the top of the coating peaks down to the substrate (#1). Couplant fills the voids between the probe and the coating (#2) creating an additional interface. If echoes from the couplant/coating interface (#2) are stronger than the coating/substrate interface (#1), an adjustment (increase) of Lo Value may be required for the Gage to display the weaker (#1) echo.
A significant echo occurs at the probe/coating interface. The relative strength of this echo compared to the coating/substrate echo requires that Lo Value be increased.
Multiple coating/coating/substrate interfaces may generate several echoes. The user may need to adjust the Gage’s Set Range to ignore echoes from coating/coating interfaces.
Some common reports received by our Service Department along with possible causes. Most conditions however can be cleared with a Reset.
Make sure the + and - battery terminals are positioned properly and that fresh batteries are being used.
Gage may be measuring surface roughness. Raise the value of Lo Range.
Gage may be measuring both the coating and substrate. Lower the value of Hi Range.
Make sure to hold the probe in the air and ensure the probe is free of couplant and the probe tip area is clean. If problem persists, note the error message and contact our technical support department.
This occurs when the Gage is unable to obtain a measurement result. Ensure sufficient couplant (gel) has been applied to the surface of the coating and repeat measurement.
When the Gage is set up for multiple layers, “----” will be displayed for each layer the Gage is unable to obtain a measurement result for. The most common reasons for this is that the individual layers are too acoustically similar or are too thin for the Gage to distinguish between them. Reduce the number of layers the Gage is set up for and repeat measurement.
Power Source: 3 AAA alkaline, Lithium or optional Nickel-metal hydride (NiMH) rechargeable batteries. For best battery indicator results, ensure the appropriate
The battery indicator displays a full bar with fresh alkaline or fully charged batteries installed. As the batteries weaken, the bar will be reduced. When the battery symbol is low the Gage can still be used, but the batteries should be changed or recharged at the earliest opportunity. The Gage will turn off automatically when batteries are very low, preceded by a Low Battery Warning on the display.
To retain all user settings and stored memory readings, only replace the batteries after the instrument has powered-down. Battery performance decreases at low temperatures.
Rechargeable Battery Pack
4 - AAA eneloop batteries
The PosiTector can operate on rechargeable batteries and DeFelsko recommends the use of eneloop (NiMH) rechargeables. eneloop batteries combine the advantages of regular rechargeable batteries and disposable (Alkaline) batteries. They discharge very slowly and can be stored for long periods without having self discharge concerns. Eneloop batteries come pre-charged and ready to use immediately. See: www.eneloop.info
AC Power Cable
An optional AC Power Cable Kit is available for continuous operation or battery charging through the PosiTector’s built-in USB port. This kit supplies several alternate power solutions for your battery-operated PosiTector. They allow the gage to operate continuously without the need for batteries.
Use the usb cable alone to connect a PosiTector to your PC's built-in USB port that acts as a continuous power source. Or connect the cable to the included power adaptor which plugs into any AC wall electrical outlet, 110 or 220V.
A selection of electrical plugs is included which are capable of dealing with most country’s outlets.The USB cable provided can also be used for Accessing Stored Measurement Data.
A USB Cable is provided with every PosiTector. The USB cable can also be used for Accessing Stored Measurement Data via the PosiTector USB port or to a connect to a PC's built-in USB port to act as a continuous power source. Replacement USB cables are available.
One 4 oz. bottle of Ultrasonic couplant (gel) is provided with every PosiTector 200 probe. Additional 4 oz. bottles are available and sold in a cases of 12.
Convenient soft shell nylon case for carrying a PosiTector. Case has compartments for Certificates of Calibration, instruction manuals and other accessories.
Protective Lens Shield
One lens shield is included with every PosiTector instrument. Additional package of five (5) thin plastic lens shields are available and ideal for protecting the PosiTector display from paint and overspray.
Certified thickness Standards are used to verify the accuracy and operation of coating thickness gages and are an important component in fulfilling both ISO/QS-9000 and in-house quality control requirements. Contracts often specify that coating thickness measurements be taken by gages whose measurement accuracy is traceable to a National Metrology Institute such as NIST or PTB.
Standards are typically purchased as an accessory to coating thickness gages. Many customers find it more practical to verify the accuracy of their own gages in-house, rather than utilize DeFelsko’s calibration services. This is particularly true when many gages are in use and/or when accuracy verification is performed often.
There are 4 types of coating thickness standards available:
Certified Coated Metal Plates are the best solution for verifying the calibration, accuracy and operation of most magnetic, eddy current or ultrasonic coating thickness gages. They fulfill both ISO and in-house quality control requirements. At ±0.43µm (±0.017 mil) Certified Coated Metal Plates are the most accurate solution.
Certified Polystyrene Blocks are for use with C and D probes.
Certified Plastic Shims (foils) provide an economical alternative to coated metal plates. They have a reduced accuracy of ±2 µm (±0.08 mil). A coating thickness Gage measures shim thickness when this shim is placed over a rigid, flat surface.
Non-Certified Plastic Shims (foils) provide a quick operational check of the Gage and they allow the user to perform practice measurements when placed over a rigid, flat surface. A set of 5 shims is included with every PosiTector 200 probe.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Before returning the Gage for service…
- Install new or newly recharged batteries in the proper alignment as shown within battery compartment.
- Examine the probe tip for dirt or damage.
- Perform a Hard Reset and a Zero
- Place a plastic shim onto a hard surface (i.e. glass) and attempt a measurement.
If you must return the Gage for service, please fill out and include the Service Form located at www.defelsko.com/support with the Gage. Be sure to also include the probe, your company name, company contact, telephone number and fax number or email address.
