RS485 COD sensor For Industrial Waste Water Treatment

1. Applications

The COD sensor is Kacise's new generation of environmentally friendly COD / TOC sensors. It does not require reagents, is non-polluting, is more economical, and is more environmentally friendly. The water volume is small, easy to install, and water quality monitoring can be performed online. Automatically compensates for turbidity disturbances and is equipped with an automatic cleaning device that maintains excellent stability even over long periods of time.

2. Feature 

• Digital sensor, RS-485 output, support MODBUS
• No reagents, no pollution, more economical, more environmentally friendly
• Can measure SAC, COD, TOC and other parameters
• Automatically compensates for turbidity interference for outstanding test performance

3.Measuring principle

Many organic substances dissolved in water absorb ultraviolet light. Therefore, by measuring the absorption of these organic substances by ultraviolet light at a wavelength of 254 nm, the total amount of organic pollutants in water can be measured. The kacise COD series sensor uses two light sources, one 254nm ultraviolet light and one 850nm infrared light, which can automatically compensate the optical path attenuation and turbidity effects, thus achieving more stable and reliable measurement values.
