Amprobe TH-3
Relative Humidity Temperature 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
-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, and
Relative.
The TH-3 is a complete package and comes with soft
carrying case, sensor cover, battery and manual.
- Dual display
- Relative function monitors humidity and temperature changes
- Extended probe stem to easily access air ducts
- Min/Max readings
- Data Hold
- Capacitive sensor with protective cover
- Auto Power off
- Soft Carrying Case
