Water Quality Monitor

1. Water Quality Monitor Product Introduction

1. Overview

Water Quality Monitor can continuously monitor water quality parameters, which is essential to ensure water resource management, environmental protection and public health.QSZ2Water Quality Monitor is a comprehensive sensor acquisition, display and analysis system based on Internet of Things technology. It is a water supply quality monitoring microsystem, consisting of a steady flow exhaust unit, an analysis and testing unit, a system control unit and a remote communication unit, and has complete power supply, lightning protection, network communication and other functions.

2. Product positioning

QSZ2Water Quality Monitor has automatic monitoring function. The main monitoring items of the integrated extractable micro water quality automatic monitoring station are: PH, temperature, turbidity, conductivity, dissolved oxygen, COD, ammonia nitrogen, suspended solids, total nitrogen, etc. It adopts highly integrated technology and realizes automatic water quality monitoring function in one cabinet.

Water Quality Monitor can be widely used for online water quality monitoring in rivers, urban or village water plants, water supply networks, secondary water supply, user terminals, 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 affairs management, and health supervision.
