Probe Options

Built-in Probe (DPM)

  • Integral probe with Direct Contact Surface Temperature Sensor
  • Measures dew point, relative humidity, air temperature and surface temperature

Built-in Probe w/Cabled Surface Temperature Sensor (DPMS)

  • Includes built-in air temperature/humidity sensor and K-type connector

  • Magnetic surface temperature sensor with armored cable and locking device to prevent accidental disconnection from the instrument during unattended operation.

  • Includes magnetic tab to attach the gage body onto steel structures

  • Additional Sensors for DPMS Probe (K-Type Thermocouple Sensors)

    • A. Hand-held Surface Temperature Sensor - for spot checking hard-to-reach surfaces

    • B. Self-adhering Surface Temperature Sensor - sticks to solid materials including aluminum, wood, concrete, etc. Ideal for unattended monitoring

    • C. Liquid Temperature Sensor - general purpose sensor with stainless steel shaft

      Easily converts to accept other optional K-type sensors.
