Product Description：
COD-210 is a new type of UV254 COD sensor introduced by DAO Yi, using ultraviolet absorption method, bringing together the industrys many years of application development experience, the sensor is small in size, integrated internal self-cleaning, the surface is treated with anti-corrosion treatment; the reaction analysis speed is fast, no chemical reagents are required, the use of deep UV LED cold light source imported from abroad, the luminescence measurement life is long, while the use of 550nm compensation light source, effectively eliminating the effect of turbidity and chromatography on the sensor measurement, with higher reliability.
Features:
1. Digital sensor, direct output of Rs-485 digital signal, support MODBUS/RTU
2. Dual optical path measurement; 254nm and 550nm compensated light source to eliminate turbidity and chromaticity effects
3. Imported UV254 LED cold light source, long life, small drift; filter film design, small interference, stable
4. Can measure parameters such as COD, TOC, turbidity and temperature, without chemical reagents and sample decomposition
5. Small size, internal integrated automatic cleaning brush, effectively prevent biological adhesion;
6. Surface for anti-corrosion passivation treatment
7. Low sensor power consumption, internal circuit anti-interference design
Sensor 3 months,brush:6months
