Temperature / Humidity


Thermo-hygrometers : measure simultaneously the temperature and the moisture of the air.



General-purpose thermo-hygrometer PosiTector DPM

According to : ISO 8502-4

The PosiTector Dew Point Meter measures and records the following climatic parameters :

  • Air temperature (from -40 to +80°C).
  • Surface temperature (from -40 to +190°C).
  • Relative humidity (from 0 to 100%RH).

The meter calculates and displays automatically the dew point temperature and the difference between surface and dew point temperature. Ideal for surface preparation as required by ISO 8502-4.

WiFi technology wirelessly synchronizes with PosiTector.net, downloads software updates, and connects to mobile devices for expanded functionality.

Bluetooth Wireless Technology for data transfer to a PC or optional portable printer.
