Introduction:
COD sensor is a UV absorption COD sensor, combined with a lot of application experience, based on the original basis of a number of upgrades, not only the size is smaller, but also the original separate cleaning brush to do one, so that the installation is more convenient, with higher reliability.
It does not need reagent, no pollution, more economic and environmental protection.On-line uninterrupted water quality monitoring.Automatic compensation for turbidity interference, with automatic cleaning device, even if long-term monitoring still has excellent stability.
Testing principle:
Many organic compounds dissolved in water are absorbent to ultraviolet light. Therefore, the total amount of organic pollutants in the water can be measured by measuring the extent to which these organics absorb ultraviolet light at 254nm.
Sensor features:
Digital sensor, RS-485 output, support Modbus
No reagent, no pollution, more economic and environmental protection Automatic compensation of turbidity interference, with excellent test performance
With self-cleaning brush, can prevent biological attachment, maintenance cycle more
