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 from
-20 °C (-4 °F) to 60 °C (140 °F). 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.
