COD-210Adopting UV absorption method, gathering years of application development experience in the industry, the sensor is compact in size, integrated with internal self-cleaning, and the surface is treated with anti-corrosion; Fast reaction analysis speed, no need for chemical reagents, using imported deep ultraviolet UV LED cold light source, long luminescence measurement life, and adopting 550nm compensation light source, effectively eliminating the influence of turbidity and chromaticity on sensor measurement, with reliability.
COD sensorCharacteristics:
1. Digital sensor, directly outputs Rs-485 digital signal, supports MODBUS/RTU;
2. Dual optical path measurement; Compensate light sources at 254nm and 550nm to eliminate turbidity and chromaticity effects;
3. Imported UV254 LED cold light source with long lifespan and low drift; Filter design, minimal interference, stable;
4. It can measure parameters such as COD, TOC, turbidity, and temperature without the need for chemical reagents or sample digestion treatment;
5. Small in size, with an integrated automatic cleaning brush inside, effectively preventing biological attachment;
6. Surface anti-corrosion and passivation treatment;
