Product Description

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
