DeFelsko PosiTector DPMA1-G Standard Dew Point Meter With PRBDPMA-C Integral Probe With Wind Speed Sensor. The DeFelsko DPM Dew Point Meter measures and records climatic conditions such as relative humidity, surface temperature, air temperature, dew point temperature, and wind speed. The Dew Point Meter also finds the difference between surface and dew point temperatures. The DPM is ideal for environmental monitoring and surface preparation. This Gage is weatherproof - resistant to water, dust, oil, solvent, and acid. When using the Dew Point Meter, there's no need to consult complex tables or a slide rule calculator. All readings are being updated constantly, on top of displaying simultaneously. If climate conditions are unsuitable for painting, an alarm will indicate the difference.
The DPM Dew Point Meter is available in both Standard and Advanced models, with user's choice of integral or cabled probe. The integral probe has several options with varying features, including a direct contact surface temperature sensor, an infrared surface temperature sensor, a cabled surface temperature sensor, and wind speed. The cabled probe includes 0.5" NPT threads. Standard models can store or download up to 1000 readings per probe and Advanced models can store or download up to 250,000 readings in up to 1,000 batches and sub-batches. The Advanced gage model also utilizes Wifi and Bluetooth technology.
