[High Accuracy]: The object distance ratio is 12:1, allowing for accurate temperature measurement from a distance. High-quality sensors enable measurements in less than 0.5 seconds. Accuracy is 1.5% or 1.5C, suitable for a wide range of everyday applications. [Widely Used]: Ideal for measuring engines, tires, electrical equipment, heating and cooling systems, furnaces, hot water, oil, cooking grills, refrigerators, TVs, air conditioners, and other common household and industrial surfaces. [Unique Functions]: Switch between MAX/MIN/AVG/EMS/CAL modes using the mode button. MAX displays the highest temperature recorded, MIN shows the lowest, AVG automatically displays ambient temperature, EMS allows emissivity adjustment (0.101.00), and CAL enables temperature self-calibration. [Operation and Display]: Features a large LCD with backlight for clear visibility in low-light conditions. The device activates automatically when the measurement button is pressedno power switch required.
