Any natural object will radiate infrared radiation to its surroundings. Thermal imaging technology refers to the use of optical imaging objective lens and infrared detector to receive the infrared radiation energy of the measured target and reflect it to the photosensitive e-lement of the infrared detector,so as to obtain a circular figure of the thermal distribution on the surface of the object. This thermal imager corresponds to the thermal distribution field on the object. Generally speaking, infrared thermal imaging is to transform the invisible infrared engergy emitted by an object into a visible thermal i-mage, that is, the i-mage of temperature distribution on the target surface. Features: The thermal imaging s-ensor can capture the infrared resolution of 220-150, which makes it easy to judge the exact exit point. 7 color imaging modes. Built-in rechargeable battery, USB charging design, you don't need to worry its battery. Large capacity storage. Standard 16GB mini memory card with large capacity can store various measurement i-mages. USB to read i-mages quickly. The captured pictures saved in the instrument can be viewed and exported by connecting to a computer, which is convenient and quick.
