The COD sensor is a new generation of environmentally friendly COD
sensor launched by our company. It requires no reagents,
no pollution, and is more economical and environmentally
friendly. Small size and easy installation, water quality
monitoring is available online. Automatic compensation for
turbidity disturbances, with automatic cleaning, for excellent
stability even for long-term monitoring.
Measuring Principle
Many organic substances dissolved in water absorb ultraviolet
light. Therefore, the total amount of organic pollutants in water
can be measured by measuring the absorption of these organic
substances by ultraviolet light at a wavelength of 254 nm. COD
sensors use two light sources, one 254nm ultraviolet light and one
550nm infrared light, which can automatically compensate the
optical path attenuation and turbidity effects, thus achieving more
stable and reliable measurement values.
