COD Analyzer

Based on the Lambert Beer absorption law, high-brightness UV LEDs of specific wavelengths are used to irradiate the organic substances in the water sample. The intensity signal after absorption is related to the content of organic substances. The sensor adopts a digital and intelligent sensor design concept, which can automatically compensate for the influence of light source fluctuations and device aging on the measurement values. It directly outputs standardized digital signals, and can achieve networking and system integration without a controller.
