-Overview-
The MDS-CH061 Online Self-Cleaning Chlorophyll Sensor is a digital water quality monitoring device that adopts the fluorescence method. Equipped with a built-in automatic cleaning brush, it can effectively prevent fouling, adhesion, and bubble interference. It is suitable for long-term online monitoring of various water environments such as rivers, lakes, oceans, and aquaculture water bodies.
The sensor directly outputs RS-485 signals and supports the MODBUS/RTU protocol. It integrates a temperature sensor to realize real-time data collection and automatic temperature compensation. With a sturdy structure and an IP68 protection rating, it supports multiple installation methods, including submerged, floating, and pipeline types, facilitating deployment in different scenarios.
Featuring a self-cleaning system, the sensor is easy to maintain and can work stably for a long time. It applies to the research and investigation of algae and phytoplankton, as well as dynamic water quality monitoring.
-Features & advantages-
The sensor features a self-cleaning system, simplifying maintenance and ensuring continuous and stable operation. It is suitable for research, surveys, and dynamic water quality monitoring of algae and phytoplankton.
Digital sensor, directly outputs RS-485 digital signal, supports WODBUS/RTU, can continuously monitor online, and track water quality dynamics in real time. Includes an automatic cleaning brush to prevent contamination and eliminate air bubbles, and has a built-in temperature sensor.
