[Product Overview]
The FST100-SZXT04 float water quality monitoring system can achieve simultaneous measurement of multiple water quality parameters, including dissolved oxygen pH、ORP、 Conductivity and turbidity, etc., are collected directly by external DTU issuing collection instructions to the sensors. The returned data from sensors at different addresses are transmitted, and users can obtain real-time monitoring data. The water quality monitoring system based on buoys is an integration of chemical analysis instruments and various water quality sensors, combined with modern data acquisition and processing technology, data communication technology, buoy design and manufacturing technology. It is an effective technical means to achieve automation, networking, and online monitoring of environmental water quality.
[Product Features]
●Universal RS485 interface, Modbus/RTU protocol
●Easy to connect to third-party devices such as industrial control computers, general controllers, recording instruments, PLCs, DCS, etc;
●Double high impedance differential amplifier, strong anti-interference and fast response speed;
●Direct input installation. The installation of the buoy system does not require land occupation, reducing the cost of land occupation;
●All sensors are easy to disassemble, reducing subsequent maintenance and repair costs;
●Protection level IP68
[Scope of Application]
Fluorescent dissolved oxygen sensors are widely used in water quality monitoring scenarios such as aquaculture, sewage treatment, rivers, lakes, and drinking water.
