surface of the object, with the measurement ranges of -50℃ to 550℃. 【LCD Display】: LCD display with backlight, you can see the measurement data clearly, easy to use even under poor illumination. 【Multifunctional Design】: Support the measurement of max value, min value, AVG value, the difference between the maximum value and the minimum value. With high temperature alarm, low temperature alarm, low battery alarm, 6s no operation automatic shutoff and data hold funtion. 【Laser Target Positioning】: Support laser target aiming and positioning quickly lock to the measurement ranges, and the measurement value is more accurate. 【12:1 Object Distance Ratio】: Accurate positioning measurement, the ratio of the measurement distance to the diameter of the measurement target (the object distance ratio is D:S) is 12:1. 【℃ and °F Switch Function】: Two temperature measurement units (Celsius C°/ Fahrenheit°F) one button to switch, more convenient measurement according to real-time needs.
