Online cod sensor rs485 cod probe Chemical Oxygen Demand Waste Water Treatment bod cod sensor
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 for the optical path attenuation and turbidity effects, thus achieving more stable and reliable measurement values.
The optical method online COD sensor (Chemical oxygen demand sensor) is more economical and environmentally friendly than the traditional chemical method. Small in size, easy to install, and can be used for continuous online water quality monitoring. Automatic compensation for turbidity disturbances, with automatic cleaning device, optional titanium alloy (corrosion resistant).
COD sensors are mainly used for monitoring rivers, lakes, sewage, and other types of surface water, etc., and can be easily integrated into water quality monitoring systems to meet customer needs.
* Digital sensor, RS-485 output, support MODBUS
* No reagents, no pollution, more economical and environmentally friendly
* Can measure SAC, COD, TOC, and other parameters
* Automatic compensation for turbidity interference for excellent test performance
