This BENETECH GM1150 Infrared Thermometer (-50℃ - 1150℃) applies the principle of infrared for inducing surface temperature of a object， particularly high temperature object. It is especially widely used in steel casting， machine components， furnace temperature， glass， etc. Sophisticated manufacture makes it feature high precision， high resolution and low repeatability. LCD screen with backlight design enables you to get data easily and clearly even in the dark. This infrared thermometer is a complete combination of maximum / minimum /average value / D-value， high / low temperature alarm setting， data storage function， etc. It is convenient and helpful without contact object directly. What a practical tool!
