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.
Features
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
