Built-in rechargeable lithium battery, Micro USB interface, no need to worry about power. The refresh rate is 8Hz, the target temperature measurement range is -40~+300, and the operating environment is 10~50. Emissivity is adjustable from 0.1 to 0.99. Sensor probe field of view, default 75 degrees * 110 degrees MLX90640ESF-BAA probe. The 2.4-inch LCD screen has a resolution of 320*240, and the screen displays the highest temperature, the lowest temperature, the temperature of the central point, and each coordinate point. There are two color modes to choose from: Iron Red and Rainbow. With camera function, built-in memory, can take 100 photos, no need to use other tools, use Micro USB cable to directly connect to computer, you can browse, copy, delete pictures. It can be applied to human body temperature detection, PCB component heating temperature detection, floor heating temperature detection, auto parts temperature detection, electrical switch temperature detection, air conditioner microwave oven detection, etc. Note: It is recommended to fully charge the thermal imager before connecting it to the computer, and then connect it to the computer after turning it off. packing list: 1 * thermal imager 1 * USB data cable 1 * Lanyard Specification: Material: ABS Color: blue+red Resolution: 32*24 1.
