Factory China UV254 COD /BOD / TSS Sensor Chemical Oxygen Demand Meter
Measuring principle
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. COD
sensors use two light sources, one 254nm ultraviolet light and one
550nm infrared light, which can automatically compensate the
optical path attenuation and turbidity effects, thus achieving more
stable and reliable measurement values.
COD Sensor Feature
Digital sensor, RS-485 output, support MODBUS.
Can measure COD, BOD and temperature parameters.
No reagents, no pollution, more economical and environmentally friendly.
Small size and easy to install, water quality monitoring can be
performed online.
It automatically compensates for turbidity interference and has
excellent test performance.
Internal rotation cleaning brush for pipe self-cleaning and submersible self-cleaning
