Principle Its working principle is the law of black body radiation The higher the temperature of the object the stronger the infrared radiation ability it emits The temperature data is processed by the chip and displayed on the screen Feature The target temperature measurement range is 40 300℃ and the dynamic refresh rate is 8Hz The resolution of the 32 inch LCD screen is 320 240 The screen can display and track the highest temperature and the lowest temperature at the center point The shell uses FR4 epoxy sheet which can better protect the internal components is not easy to damage and has a long service life mini size easy to carry you can take it anywhere you want to use it Powered by lithium battery the battery life can be up to 10 hours by USB C charging and it is very convenient to use while charging when there is no power The built in SPI Flash chip can store 100 pictures and the data cable can be connected to a computer or mobile phone to view and copy the image files Specification Product size 95 60 20mmProduct weight 130gMaterial epoxy sheet printed circuit boardInfrared sensor MLX90640ESF BABHardware resolution 32 24 pixel far infrared arrayScreen resolution 320240 pixelsTemperature measurement range 40℃ 300℃Measurement accuracy ±2℃Working temperature 0℃ 50℃Working humidity ≤70 Refresh rate 8HzField of view horizontal 55 vertical 35Emissivity 0 95Charging specification USB Type C 5V 1AProduct size 95 6220mm Product weight gP
