PosiTector® SmartLink PosiTector Dew Point Meter (DPM) probes continually measure, calculate and record climatic readings, quickly and accurately. This instruction manual specifically covers use with PosiTector SmartLink. The PosiTector SmartLink and free mobile app allow you to wirelessly connect a wide selection of PosiTector probes to your smart device. Take full advantage of your device's keyboard, microphone, camera, internet data connection, etc. to simplify and enhance your measurement inspection process.
The PosiTector SmartLink measurement solution consists of a PosiTector App, PosiTector SmartLink device and compatible PosiTector probe. In addition to the PosiTector DPM, compatible probes include the PosiTector SPG/RTR-H (surface profile) and 6000 (coating thickness). Why is Measurement Important? Temperature - It is important to measure both surface and air temperatures as they are often different. Application at incorrect temperatures can cause defects including: blistering, pinholing, cratering, dry spray & mud cracking. By measuring surface temperature it is possible to avoid potential application problems if air or surface temperatures become too hot or too cold for satisfactory film formation. Surface and air temperatures directly affect the rate of cure of the applied coating or lining system and are major factors in the formation of surface moisture or dew. ASTM D3276 Standard Guide for Painting Inspectors (Metal Substrates) states that the minimum air/surface temperature is usually 5°C (40°F). Relative Humidity - the amount of moisture in the air expressed as a percent of overall volume. High relative humidity can retard the rate of solvent evaporation. For this reason, the maximum relative humidity at which coatings or linings can be applied and cured is generally set at 85%. This can be set as an alarm in the Advanced model. Dew Point Temperature - the temperature at which moisture will begin to form on a surface. The dew point temperature is a function of air temperature and the relative humidity. (see ISO 8502-4 Annex A). It is the temperature to which a volume of air must be cooled in order to reach saturation. A number of major standards organizations call for careful dew point control. Moisture on a freshly blasted steel substrate will cause the steel to rust. If a thin, invisible film of moisture is trapped between the applied coating and the substrate, the system will likely fail prematurely. To ensure that dew point problems do not exist, ISO 8502-4 and SSPC guidelines state that the surface temperature must be a minimum of 3°C or 5°F above the dew point during the 3 critical phases of coating preparation, application, and cure. Calibration Written Calibration Procedures are available online at no charge. http://www.defelsko.com/quality/calibration_procedures.htm  The PosiTector SmartLink powers-up when the LED button is pressed. To preserve battery life, the PosiTector SmartLink powers-down after 5 minutes of no activity. Alternatively, press and hold the LED button until it turns red and shuts off (approximately 5 seconds). All probe settings and calibration adjustments are retained within the PosiTector SmartLink, stored measurement data is retained within the smart device (cell phone, tablet). 1. Wirelessly Connect the PosiTector probe to the smart device using the PosiTector App. 2. Remove the protective rubber cap from the surface temperature sensor. Measure A typical screen consists of RH, Ta, Ts, Td, Ts-Td and Tw readings. This group of readings is referred to as a dataset.
RH - The relative humidity sensor is located inside the vented area of the probe housing. The sensor may require a longer period to stabilize in the event of extreme humidity changes. Ta - The air temperature sensor is located inside the vented area of the probe housing. (Also known as Dry Bulb temperature) Ts - A surface temperature thermocouple is located on the tip of the probe (built-in probe model). It is spring loaded and designed to quickly self-align on a surface. Press it against a surface and allow a few seconds for the value to stabilze. Do not drag the sensor over the surface, Wet the surface for a faster response. Cover with the included protective plastic cap when not in use. For surface temperature measurement on steel over an extended of time, consider using a PosiTector Standard or Advanced model with optional Magnetic Surface Temperature probe. Both models feature Auto Log mode for monitoring climatic parameter over extended periods of time.

It is the temperature to which a volume of air must be cooled in order to reach saturation. Ts -Td - The surface minus dew point temperature is important in judging the risk of condensation, or dew, forming on a surface. For example, ISO 8502-4 recommends that, unless otherwise agreed, the temperature of a steel surface generally should be at least 3°C (5°F) above the dew point when paints are applied. Tw - The wet bulb temperature is the temperature of adiabatic saturation. This is the temperature indicated by a moistened thermometer bulb exposed to air flow. The wet bulb temperature is calculated from Ta and RH using an air pressure of 1.0 atmospheres (1013 mbar). It approximates the temperature indicated by a moistened thermometer bulb exposed to airflow. Variations of Tw at other pressures could be greater than +1°C (+2°F).
Smart Trend Indicators
While the absence of an arrow does not necessarily signify stability, it can be taken to mean that particular reading is undergoing little or no change. Slow changes could therefore occur without being noted by an indicator arrow. The PosiTector App connects a PosiTector SmartLink to your smart device enabling you to use PosiTector 6000, DPM, SPG or RTR-H probes on your device without the need for a conventional gage body. Screen fonts, brightness and displayed language are inherited from your smart device settings. Currently, the PosiTector App has language support for English, Spanish, French, German, Chinese and Korean. Screen orientation is fixed to portrait only, rotation to landscape is not supported. Stored datasets, images and notes are all stored in the PosiTector App (on your smart device). The number of stored datasets is only limited by the memory available on your smart device. If the application is removed or a menu Reset is performed, all stored datasets and associated data is permanently erased.
Wirelessly Connecting the PosiTector App to a PosiTector DPM probe 1. Power-up the PosiTector SmartLink and connected DPM probe by pressing the LED button. The button will blink blue. 2. Select the PosiTector SmartLink App icon on your smart device. 3. Select Continue. A list of available PosiTector probes (listed by connected probe type and serial number) will be displayed. Select the desired PosiTector SmartLink to connect. The LED button on the PosiTector SmartLink will illuminate solid blue when successfully connected.

PosiTector DPM probes continually measure, calculate and record climatic readings. Two probe models (Built-In and Separate) are offered, as pictured below.
Optionally, the magnetic surface temperature probe can be disconnected from the K-Type thermocouple connector (separate probe models only) and replaced with one of the following K-Type probes: Hand-held Surface Temperature Probe - for spot checking hard-to-reach surfaces Self-adhering Surface Temperature Probe - sticks to solid materials including aluminum, wood, concrete, etc. Ideal for unattended monitoring. Liquid Temperature Probe - general purpose probe with stainless steel shaft CAUTION: To ensure optimal performance of your PosiTector DPM, do not obstruct the airflow near the air temperature and humidity sensors. Keep fingers away from the sensor, as body heat can cause incorrect readings. Allow time for the instrument to acclimate and for the readings to stabilize when moving the instrument between different environments. When using the surface temperature probe, do not use excessive downward force, and do not drag it sideways.
