Relative Humidity Temperture Meter

The TH-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 -20C (-4F) to 60C (140F).

the sensor is mounted on a ling 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, and relative. 

The TH-3 is a complete package and comes with soft carrying case, sensor cover, battery and manual.
