Product Description

Digital COD Sensor

The total amount of organic pollutants in the water can be measured by

measuring the degree of absorption of these organic substances to 254nm

wavelength ultraviolet light.

The COD 351 digital sensor adopts two light sources, one 254nm ultraviolet

light, and one turbidity compensation, which can automatically eliminate the

interference of suspended substances in the water, so as to achieve more

stable and reliable measurement.

Features

RS-485 output, support Modbus

No reagents, no pollution, environmentally friendly

Can measure COD, TOC, turbidity and temperature

Automatically compensate for turbidity interference

With self-cleaning brush and the maintenance cycle is longer
