The 889A digital thermometer can perform non-contact measurements of surface temperatures. The most attractive features of the digital thermometer are its clear laser point, the wide temperature range and the adjustable emissivity (depending on the material). Thanks to its high distance-to-spot ratio of 30:1, you can measure an object's temperature from a substantial distance. When standing near to the object to be measured, it is also possible to determine the temperature of small construction parts, due to the small measuring point diameter. The adjustable emissivity allows you to perform more accurate measurements ondifferent materials.
