COD-160 Online Digital Sensor
(RS-485/ModbusRTU)
Many organic compounds dissolved in water absorb UV light. Therefore, by measuring the degree of absorption of 254nm wavelength ultraviolet light by these organic substances, the total amount of organic pollutants dissolved in the water can be accurately measured.
The COD-160 online digital sensor uses two light sources, one is 254nm ultraviolet light, and the other is 365nm ultraviolet reference light. It can automatically compensate for the attenuation of the optical path and remove the interference of granular suspended impurities to a certain extent, thereby achieving more stable and reliable measurement.
Applications
All types of water treatment (rivers/lakes/drinking water sources/groundwater/marine water), aquaculture, environmental monitoring, CIP and related industries.
Features
● No reagents required, no pollution, more economical and environmentally friendly
● Small size, easier to install, and capable of continuous online water quality monitoring
● Can measure parameters such as COD, turbidity and temperature
● Automatic compensation for turbidity interference
● Comes with cleaning brush to prevent biological adhesion
● Small drift, fast response, and more accurate measurement
● Even with long-term monitoring, it still has good stability
● Maintenance-free, long service life, low cost of use
● Digital sensor, RS-485 interface, Modbus/RTU protocol
● Low power consumption design, anti-interference design
