Digital COD Sensor
Description
The total amount of organic pollutants in the water can be measured by measuring the degree of absorption of these organic substances to 254nmwavelength 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
