COD传感器如何在高污染场景中“站稳脚跟”
This sensor employs ultraviolet absorption spectroscopy (254 nm wavelength) and, based on the Lambert-Beer law, calculates the COD value by measuring the absorption intensity of ultraviolet light by the water sample. It requires no chemical reagents, produces no secondary pollution, and has a response time of only a few seconds, truly achieving "measure and obtain immediately," completely eliminating the cumbersome process of traditional laboratory digestion methods.
