IQCOD Chemical Oxygen Demand (COD) Sensor accurately measure the level of organic pollutants by detecting how much UV light is absorbed at a wavelength of 254 nm. The sensor uses two light sources: one ultraviolet light to measure the COD (Chemical Oxygen Demand) content, and another reference light to assess the water’s turbidity.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAdditionally, IQCOD sensor employs a specialised algorithm that compensates for any loss of light along the path and reduces the impact of suspended particles in the water.
