DS500 series COD sensor is a new generation of environmental protection type COD sensor launched by our company, which is reagent free, pollution-free, more economic and environmental protection. Small size, more convenient installation, online continuous water quality monitoring. Automatic compensation for turbidity interference, with automatic cleaning device, even long-term monitoring still has excellent stability.

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. DS500 series sensors use 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.

Features of DS500 series COD sensor:

1. Digital sensor, RS-485 output, support MODBUS

2. No reagents, no pollution, more economical and environmentally friendly

3. Automatic compensation for turbidity interference for excellent test performance

4. Can Test COD/BOD/TSS at same time

5. Built-in Temperature
