[High Accuracy]: The object distance ratio is 12:1, which can measure the over a long distance. 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//CAL mode, MAX: display the highest temperature during measurement, MIN: display the lowest temperature during measurement, AT: automatically display the current temperature , : Adjust tolerance (0.1~1), CAL: Temperature self-calibration[Operation display]: 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 operationA.
