[High Accuracy]: The object distance ratio is 12:1, which can measure the target over a long distance. High quality sensors can be used to complete measurements in less than 0.5 seconds. Measuring accuracy is +/-1.5% or +/-1.5C, suitable for most everyday life. [Household use, etc. Widely used]: measuring engine, tires, electrical equipment, heating and cooling equipment, hot furnaces, etc., measuring the temperature of hot water and oil in life, cooking grill, refrigerator TV air conditioner and other product temperatures [Unique function]: Use the mode switch button to switch between MAX/MIN/AT/EMS/CAL mode, MAX: display the highest temperature during measurement, MIN: display the lowest temperature during measurement, AT: automatically display the current ambient temperature , EMS: Adjust tolerance (0.1~1), CAL: Temperature self-calibration [Operation display]: Large LCD display with high stability and backlit display, which can display dark reading values; no need for power switch, just press the measurement button to start operation A. Digital temperature Introduction This Thermometer is used for measuring the temperature of the object's surface, which is applicable for hot, hazardous or hard toreach objects without contact safely and quickly.
