The company has many years of experience in developing and manufacturing infrared function and infrared blackbody temperature correction equipment, and has been successfully developed by Zhongshan Scientific Research Institute. In recent years, the infrared emissivity measuring device developed at 34 ℃ has been able to accurately measure the infrared emissivity of objects. The far-infrared radiation rate measured at 34 ℃ in line with the human body surface temperature is objective, fair and reliable. In the future, when Chinese people buy far infrared materials in the market, they can provide a correct choice of materials with high radiation rate at 34 ℃ to manufacture products with normal infrared radiation rate.
