  • Dual display
  • Relative function monitors humidity and temperature changes
  • Extended probe stem to easily access air ducts
  • Min / Max readings
  • Data Hold
  • Capacitive sensor with protective cover
  • Auto Power Off
  • Wet Bulb / Dewpoint measurements (THWD-3 only)
This high accuracy instrument measures the full range of relative humidity from 0% to 100% and features an exceptionally wide ambient temperature measurement range from –4degF to 140degF ( -20degC to
60degC). The sensor is mounted on a long shaft extending from the top surface of the unit, making probing into ductwork and hard to reach areas easier. The large LCD displays two measurements simultaneously with a full range of display options including Hold, Min, Max and Relative. The THWD-3 also measures dewpoint and wet bulb.
