DeFelsko PosiTector DPM Integral Probe

DeFelsko PosiTector DPM Dew Point Meter measures environmental conditions including relative humidity, air temperature, surface temperature, dew-point temperature, and the difference between surface temperature and dew point temperature.

SKU: DEF-PRBDPM Category: Tags: , ,


DeFelsko’s PosiTector DPM Dew Point Meter measures and records climatic conditions in surface preparation. Dew point measurement is an important and necessary aspect of preparation for coatings application, to ensure proper adhesion of coatings to surface.

With PosiTector Dew Point Meter, measurement of relative humidity, surface temperature, air temperature, dew point temperature, and difference between surface and dew point temperatures, is performed simultaneously with a single gauge, with no need to consult complex tables or use a dew point calculator. Read all measurement parameters easily on the large LCD display, store measurements internally in the gauge, download readings to your computer, or upload to DeFelsko’s cloud-based application, PosiTector DPM can be set up to AutoLog at user-selected intervals for continuous monitoring of all measurement values.

PosiTector Dew Point Meter now offers five probe styles which are fully compatible with both Standard and Advanced Gauge bodies.
