The Testo 110 (0560 1108) 1 -Channel NTC Thermometer is a highly accurate, universally applicable temperature measuring instrument. The 110 NTC Thermometer is especially designed for measurements in refrigerated rooms and buildings, and in outdoor areas. In addition to a wide selection of classical probes, a wireless radio probe can simultaneously be used (when the optional wireless module is used in the instrument). As the user, you can set your own upper and lower limit values in the instrument; as soon as these values are violated, an audible alarm sounds. In addition to this, the minimum and maximum values are clearly shown in the 2-line backlit display.
