Amprobe TH-3 Relative Humidity Temperature Meter

The Amprobe TH-3 Relative Humidity and Temperature Meter 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 duct work and hard to reach areas more easy.
