DeFelsko PosiTector Dewpoint Meter Probes

Two new probes have been added to DeFelsko's suite of PosiTector DPM Dew Point Meter probes. Users can now select between the PosiTector Standard or PosiTector Advanced gauge bodies, and any one of the four Dew Point Meter Probes. All PosiTector probes are compatible with both Standard and Advanced PosiTector bodies.*

* PosiTector RTR-3D and PosiTector PC Powder Checker probes must be used with a PosiTector Advanced gauge body.


Select from the following PosiTector DPM probes:



DPM - Integral Environmental Conditions Probe

  •   includes a built-in air temperature /relative humidity sensor to
      measure ambient temperature, RH, and dewpoint
  •   and integrated thermocouple surface temperature sensor







DPMS - Integral Environmental Condition Sensor with Cabled Surface Temperature Sensor

  • built-in air temperature / humidity sensor with K-type thermocouple connection, plus:
  • Magnetic surface temperature probe with armoured cable and locking device to prevent accidental disconnection from instrument during unattended operation
  • DPMS supplied with magnetic tab on gage boot to attach the PosiTector body to steel structures






PosiTector K-type thermocouple accepts other K-type sensors, including the following optional probes:


(A) hand-held surface temperature sensor (order code: PRBDPMHSP)


(B) self-adhering surface temperature sensor, (order code PRBDPMAP) and


(C) liquid temperature sensor (order code: PRBDPMLTP)




DPMA  -  Integral Ambient Probe with Wind Speed Sensor

  • includes built-in air temperature, humidity, and surface temperature sensors from the PosiTector DPM integral probe, plus a hot-wire anemometer to measure wind speed
  • measures air temperature, relative humidity, and wind speed while in anemometer mode
  • choice of wind speed measurement units: m/s, km/h, mph, ft/s, ft/m, knots
  • wind speed accuracy of + 3%
  • auto-rotating display for inverted use







DPMD - Cabled Air Temperature, Dew Point, and RH Probe with ½" NPT Threads

  • measures rh, dewpoint, and air temperature
  • ½" NPT threads for insertion into tanks & pipes (max 200 psi / 1.3 MPa)
  • sintered aluminum housing protects sensors








DPM IR - integral ambient sensor plus infrared surface temperature probe

  • measures environmental conditions: air temperature, relative humidity, and dewpoint using PosiTector's DPM ambient sensor
  • measures non-contact surface temperature using the new InfraRed surface thermometer
