The Extech RH210 hygro-thermometer is a compact, handheld instrument designed to take quick, accurate measurements of relative humidity, dew point, and temperature. It is ideal for applications in water restoration, clean rooms, offices, storage facilities, greenhouses, painting, HVAC, factories and others.

The RH210 measures humidity from 10 to 95%, dew point from -13.5 to 120°F, and temperature from 32 to 122°F. It utilizes a precision capacitance sensor for accurate measurements in all conditions. Test results are displayed on a large, dual LCD display. The meter includes Min/Max and Data Hold functions and auto power off (with disable) to save battery life, which make them perfect for field or home use. These portable meters are easy-to-use, precise, and economically priced to meet your budget.
