KWS-150 Online COD Sensor_Low Power

Many organic compounds dissolved in water absorb UV light. Therefore, by measuring the degree of absorption of 254nm wavelength ultraviolet light by these organic substances, the content of dissolved organic pollutants in water can be accurately measured.

KWS-150 online COD sensor uses two light sources, one ultraviolet light is used to measure the COD content in water, and one reference light is used to measure water turbidity. In addition, a specific algorithm is used to compensate for the attenuation of the light path and eliminate granularity to a certain extent. interference from suspended impurities, thereby achieving more stable and reliable measurement.
