The environmental conditions during pre-treatment and application of a coating system are major factors affecting the long-term performance of coatings on steel structures. Dew Point Meters can be used to monitor environmental conditions before, during, and after painting. Ideal for surface preparation as required by ISO 8502-4, an electronic Dew Point Meter determines the likelihood of dew forming on structures which are being painted.

Depending on the model selected, PosiTector DPM Dew Point Meters measure and record climatic conditions including: relative humidity (%RH), air temperature, surface temperature, dew point temperature, the difference between surface and dew point temperatures (Delta), wind speed, and wet bulb temperature.

The PosiTector IRT non-contact Infrared Thermometer measures surface temperatures in areas where conventional sensors will not work including hard to reach areas, moving parts, freshly sprayed powder coating, and objects whose temperatures are above the range of direct contact sensors.
