1The emissivity is adjustable, can provide better accuracy for different materials, and it is more convenient to test with high and low temperature alarm function. 2Infrared thermometers determine the surface temperature of an object by measuring the infrared energy radiated from the surface of the object. 3It is suitable for quickly measuring the surface temperature of various hightemperature, toxic or difficulttoreach objects. 4Color screen display, / switchable, automatic data retention, backlight LCD, low battery indicator, automatic shutdown function, can basically meet the needs of industrial temperature measurement. 5The shell is made of high-quality ABS material, wear-resistant and durable, not easy to damage, and long service life.
