1. Overview
• The device comprises the entire online water quality monitoring system, integrating sampling, analysis, recording, data statistics, and remote data transmission into a unified system. It is composed of a data acquisition and control unit, a communication unit, and an auxiliary unit. The auxiliary unit primarily includes subsystems such as power supply/distribution, lightning protection, and security protection. The water quality data is transmitted to the monitoring system via wireless communication for real-time monitoring and analysis.

• The device is widely utilized in water supply systems, source wells, water treatment plant, monitoring stations, surface water, and industrial water. It adopts electrode-based measurement techniques, offering advantages such as ease of installation, compact footprint, and high measurement accuracy.

2. Function

1) Water quality monitoring

The water quality monitoring instrument is designed with high-precision sensors, enabling comprehensive detection and analysis of parameters such as pH, residual chlorine, turbidity, COD (Chemical Oxygen Demand), and conductivity. It supports multiple sampling methods,including immersion,flow-through,pump suction,and buoy-mounted,while providing real-time display of water quality data and device status information via monitoring screen.

2) Automatic processing

The water quality monitoring instrument is equipped with integrated pre-treatment and storage units, which enable automated sample pre-treatment and analysis/storage of detection data.Users can directly view real-time data and export reports through the instrument.

3) Remote transmission

The water quality monitoring instrument employs multiple data transmission methods, including Ethernet, 4G, and Wi-Fi, which can achieve remote data transmission and provide effective systematic monitoring data for the water supply management department.

4) Remote configuration

The water quality monitoring instrument is equipped with an Access Point (AP) and configuration software, enabling remote adjustment of sampling and data transmission intervals.It supports remote modification and monitoring of sensor types, attributes, ID, and connectivity, while being designed for easy operation and low maintenance.

3. Installation

• For wall-mounted installation of the water quality monitor, maintain at least 70cm clearance between the back of the device and the wall to facilitate future maintenance.

• The equipment should be independently grounded. It is recommended to drive an 80cm steel pipe into moist soil and connect it to the chassis grounding terminal using a wire with a cross-sectional area of at least 4mm².otherwise it may cause unstable measurement data or damage to the electronic parts of the instrument.If the installation site has a comprehensive lightning protection and grounding system, the device can be directly connected to the existing system.

• The equipment should be equipped with lightning protection. It is recommended to connect a lightning protection module to the 220V input terminal for mains power supply. For wind solar complementary power supply, lightning protection treatment should be carried out on the pole, otherwise it may cause lightning damage.
