The Oakton 03313-70 pH basic wall-mount thermohygrometer has a 4.1-inch size for areas with limited space. Thermohygrometers are used to monitor relative humidity and temperature in laboratories, offices, greenhouses, food storage rooms, and computer rooms. This thermohygrometer has a humidity adjustment function for ease of use and an alcohol-filled thermometer for safety. Batteries or external power are not required.

The 03313-70 thermohygrometer is a basic, wall-mount unit with relative humidity range 20 to 99%, resolution of 1%, accuracy + or - 3% from 20 to 50 degrees C; + or - 8% from 90 to 100%, with synthetic hair sensor. Its temperature range is -20 to 50 degrees C (-4 to 120 degrees F), resolution 1 degree C (2 degrees F), accuracy + or - 2 degrees C (3.6 degrees F), with alcohol-filled glass thermometer sensor. Its dimensions are 4.1 (D) x 0.7 (W) inches.

A thermohygrometer is a combination thermometer to measure temperature, and hygrometer to measure humidity. It monitors relative humidity and temperature in lab, office, home, and greenhouse applications.
