Overview

The WTF201 digital UV-COD sensor, based on the Lambert Beer absorption law, uses a specific wavelength of high brightness UV LED to irradiate organic matter in water samples. The absorbed light intensity signal is correlated with the organic matter content. The sensor adopts a digital and intelligent sensor design concept, which can automatically compensate for the impact of light source fluctuations and device aging on measurement values. Directly outputting standardized digital signals enables networking and system integration without the need for a controller.
