Small Size UV254 Cod Bod Tss Analyser online Environmentally Friendly
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
