KWS-850 on-line multi-parameter sensor for dissolved oxygen and COD measurement
Product Description
The KWS-850 on-line multi-parameter sensor is a technological marvel, purposefully engineered for the precise measurement of dissolved oxygen and COD (Chemical Oxygen Demand). This state-of-the-art device offers unrivalled accuracy and reliability in water quality monitoring.
For dissolved oxygen detection, it utilizes highly sensitive probes that can capture even the minutest fluctuations, which is crucial for maintaining the vitality of aquatic life. In terms of COD measurement, it employs advanced spectroscopic or electrochemical methods, ensuring accurate quantification of organic pollutants.
Its on-line capabilities enable seamless, real-time data transmission, empowering industries and environmental agencies to take prompt action. Whether it's safeguarding the water quality in a fish farm, or ensuring compliance at a sewage treatment plant, the KWS-850 is an indispensable asset. Compact and easy to install, it's designed to meet the demands of modern water management.
Feature
- Digital sensor, RS-485 bus, Modbus/RTU communication protocol.
- Optional digital sensors such as dissolved oxygen, COD, conductivity/salinity, turbidity, ammonia nitrogen, pH, ORP, etc., suitable for long-term online monitoring.
- Integrated design, can measure 8 parameters (including temperature) at the same time.
- Equipped with an automatic cleaning device, it can effectively clean the surface of the sensor, prevent microorganisms from attaching, measure more accurately, and lower maintenance costs.
