Online Water Quality Monitor

1.Introduction to Online Water Quality Monitor

1.Overview

Online Water Quality Monitor is commonly used in municipal water treatment plants to monitor the quality of water provided to the public and can monitor multiple water qualities simultaneously.QSZ2 Online Water Quality Monitor is a comprehensive sensor acquisition, display and analysis system based on Internet of Things technology, and a micro-system for water quality monitoring.It consists of a steady-flow exhaust unit, an analysis and testing unit, a system control unit and a remote communication unit.It has complete power supply, lightning protection, network communication and other functions.

2.Product Positioning

QSZ2Online Water Quality Monitor has automatic monitoring function.The main monitoring items of integrated extraction micro water quality automatic monitoring station are: PH, temperature, turbidity, conductivity, dissolved oxygen, COD, ammonia nitrogen, suspended substances, total nitrogen, etc.It uses highly integrated technology to realize automatic water quality monitoring function in one cabinet.

Online Water Quality Monitor can be widely used in online monitoring of water quality such as rivers, urban or rural water plants, tap water pipe networks, tap water secondary water supply, user endings, indoor swimming pools, large water purification equipment and direct drinking water.It is an indispensable online analysis equipment in the fields of water plant production process control, water conservancy and water management, sanitation supervision, etc.
