Psychrometer with Infrared Thermometer
The Extech HD500 combines the functions of a humidity meter, Type K thermometer, and IR thermometer with laser spot for non-contact surface temperature readings. Measurements are displayed on a large triple LCD backlit display.
Additional Features
This 3-in-1 meter measures Relative Humidity (0 to 100 percent RH), Dew Point (-90.4 to 140 degrees F/-68 to 60 degrees C), and Wet Bulb (-6.88 to 140 degrees F/-21.6 to 60 degrees C). The HD500 also has an IR thermometer with laser spot for non-contact temperature scans -58 to 932 degrees F (-50 to 500 degrees C) with 30:1 distance to target ratio. A built-in Type K Thermometer measures air and contact surface temperature from -148 to 2501 degrees F (-100 to 1372 degrees C). Auto Power Off to conserve battery life.
