Water Quality Monitor

1. Water Quality Monitor product introduction

1.Overview

Water Quality Monitor is a general water quality multi-parameter online monitor, which can display the measured value and sensor status in real time.QSZ2Water Quality Monitor is a comprehensive sensor collection, display, and analysis system based on Internet of Things technology.It is a water supply water quality monitoring microsystem.It consists of a steady flow exhaust unit, an analysis and test 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

QSZ2Water Quality Monitor has an automatic monitoring function.The main monitoring items of the integrated extraction micro water quality automatic monitoring station are: PH, temperature, turbidity, conductivity, dissolved oxygen, COD, ammonia nitrogen, suspended solids, total nitrogen, etc.It uses highly integrated technology to implement automatic water quality monitoring functions in a cabinet.

Water Quality Monitor can be widely used for online monitoring of water quality in rivers, urban or village water plants, tap water pipeline networks, secondary tap water supply, user terminals, indoor swimming pools, large water purification equipment and direct drinking water.It is an important tool for water plant production process control., water conservancy and water management, sanitation supervision and other fields are essential online analysis equipment.
