This infrared thermometer is made of ABS material, built-in high accurate temperature and humidity sensor, quick response, the results will be given quickly. It determines the surface temperature of the object by measuring the energy reflected on the surface of the object, with the measurement ranges of -50 to 550. LCD display with backlight, the laser target and the 12:1 object distance ratio are designed for accurate positioning. With and F switchable, low battery alarm, automatic shutoff and data hold funtion. Features: Quick Measurement: ABS housing, built-in high accurate temperature and humidity sensor, with 6-14m spectral response and 500ms response time, the results will be given quickly, no need to wait anymore. High-precise Infrared Thermometer: It determines the surface temperature of the object by measuring the energy reflected on the 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/ FahrenheitF) one button to switch, more convenient measurement according to real-time needs.
