DeFelsko PosiTector DPM Dew Point Meter Probes (PTDPM-PROBES)

DeFelsko DPM Dew Point Meter Probes are designed with fast response precision sensors to provide accurate, repeatable readings. Their SmartTrend indicators identify the rising, falling, and stability of readings. Paired with each probe is an environmental sensor or NPT threads that make them ideally suited for specific and precise applications. 

The Integral probe with the Cabled Surface Temperature Sensor includes a K-type thermocouple  connector which can take measurements and auto log over periods of time. This probe also comes with a magnetic sensor. For measuring in pipes and tanks, the Cabled probe with 0.5" NPT Threads is ideal and features sintered aluminum housing to protect the sensors. The Integral Probe with the Infrared Surface Temperature Sensor allows the user to adjust emissivity. What each probe and sensor pairing can measure is listed below.
