The PosiTector DPM is a Dew Point Meter great for Environmental Monitoring. It Measures and records climatic conditions including: relative humidity, air temperature, surface temperature, dew point temperature, wind speed, and difference between surface and dew point temperatures. Ideal for surface preparation as required by ISO 8502-4, BS 7079-B4, ASTM D3276, IMO PSPC, SSPC-PA7, and US Navy NSI 009-32.
