Overview
Hospitality Enviro Tech Digital Wastewater Treatment Turbidity Sensor Many organic compounds dissolved in water are absorbent to ultraviolet light. Therefore, the amount of dissolved organic pollutants in the water can be accurately measured by measuring the extent to which these organics absorb UV light at 254nm. The COD-408 online COD sensor adopts two light sources; one is ultraviolet light for measuring COD content in water and the other is reference light for measuring turbidity in water.
Features
- No reagents, no pollution, more economical and environmental protection
- Small size, easy installation, and continuous water quality monitoring
- Measure COD, turbidity, and temperature parameters
- Automatic compensation for turbidity interference
- With a cleaning brush to prevent bio-adhesion
- Small drift, fast response, more accurate measurement
- Excellent stability even for long-term monitoring
