PosiTector® DPM L Series Dew Point Meter Loggers
Dew Point Meter Loggers

Magnetic probes attach to steel buildings to detect weather conditions.

  • Measures and records climatic conditions including: relative humidity, air temperature, surface temperature, dew point temperature, difference between surface and dew point temperatures, and wet bulb temperature.
  • Fast response, precision sensors provide accurate, repeatable readings
  • Environmentally sealed enclosure – weatherproof, dustproof, and shockproof—meets or exceeds IP65
  • Internal memory storage of 10,000 datasets (60,000 readings)
  • Conforms to ISO 8502-4, BS 7079-B4, ASTM D3276, IMO PSPC, SSPC-PA7 and US Navy NSI 009-32
