1、Water Quality Monitor System Product Introduction
1. Overview
A Water Quality Monitor System is a facility that measures water quality pollutants, such as chemical oxygen demand (COD), total phosphorus (TP), total nitrogen (TN), etc.Water Quality Monitor System is a water quality monitoring micro-system based on Internet of Things (IoT) technology. It consists of a flow stabilization and venting unit, an analysis and testing unit, a system control unit, and a remote communication unit, possessing comprehensive power supply, lightning protection, and network communication functions.
2. Product Positioning
Water Quality Monitor System features automatic monitoring capabilities. This integrated, extractive micro-water quality automatic monitoring station primarily monitors: pH, temperature, turbidity, conductivity, dissolved oxygen, COD, ammonia nitrogen, and suspended solids. It employs highly integrated technology, achieving automatic water quality monitoring within a single cabinet.
Water Quality Monitor System can be widely used for online water quality monitoring in rivers, urban or rural waterworks, water supply networks, secondary water supply systems, end-user systems, indoor swimming pools, large-scale water purification equipment, and direct drinking water systems. It is an indispensable online analysis device in water plant process control, water conservancy and water affairs management, and health supervision.

2、Water Quality Monitor System System Composition
The water quality monitoring microsystem consists of a power supply unit, a pump control unit, an analysis and testing unit, a display unit, a pump unit, a remote communication unit, and an integrated box main unit.
1. Power Supply Unit
Power supply: AC220V.
2. Pump Control Unit
Intelligent self-priming pump, maximum head: 25m, open flow rate: 1.8m³/h
3. Analysis and Testing Unit
The analysis and testing unit mainly consists of pH, dissolved oxygen, conductivity, turbidity, ORP, and temperature sensors. These sensors are fixed to the flow tank via threads or tight-fitting fasteners. The main parameters of the sensors are as follows:

| pH | 0~14 (pH) | Electrochemistry (Salt Bridge) | ±0.1PH, ±0.1℃ | |||
| 8 | cod | 0~1000mg/L | UV254 Absorption Method | ±5%, ±0.3℃ | Cod turbidity integrated; equipped with an automatic cleaner to prevent biofouling and avoid optical window contamination, ensuring long-term monitoring remains stable; automatic cleaning time and frequency can be set, power consumption is 0.7W. | |
| Turbidity | 0~400NTU | Light scattering method | ±1%, ±0.3℃ | |||
| 9 | Suspended matter | 0~2000mg/L | Light scattering method | ±5% (depending on sludge homogeneity) | ||
| 10 | Chlorophyll | 0~400ug/L | Fluorescence method | R2>0.999 | Equipped with an automatic cleaner to prevent biofouling and avoid light window contamination, ensuring long-term monitoring remains stable; the automatic cleaning time and frequency can be set, with a power consumption of 0.7W. |
Note: The sensor must not be installed upside down or horizontally; it must be installed at an angle of at least 15 degrees. The above water quality sensor operates in an environment of 0-50℃ and <0.3Mpa.
