Amprobe THWD-3 Relative Humidity and Temp Meter

The THWD-3 uses a precision capacitance sensor to deliver accurate performance with long term stability. This high accuracy instrument measures the full range of relative humidity from 0% to 100% and features an exceptionally wide ambient temperature measurement range. 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 more easy.


The large LCD displays two measurements simultaneously with a full range of display options including hold, min, max, Dew Point (DP) and Wet Bulb (WB). The THWD-3 comes with soft carrying case, sensor cover, battery and manual.
