The Wöhler 1388 infrared thermometer (IR) enables a contactless temperature measurement on e.g. wall surfaces or even in inaccessible places. Thermal bridges can be detected with this IR thermometer. Temperature differences are detected in real-time using infrared radiation at small but also large distances.
The operation of the measuring device is very easy: at the beginning, the emission factor has to be selected directly at the IR-thermometer, then you mark the temperature measuring point with the spot laser beam. The temperature can be read directly from the color display of the infrared thermometer and stored.
