The Amprobe Instruments 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 along shaft extending from the top surface of the unit, making probing into ductwork and hard to reach areas more easy.
