Water quality online monitor

The multi-parameter water quality monitor is designed for continuous online water quality measurement and intelligent control. It integrates five key water quality measurements—pH, ORP, residual chlorine, turbidity, and temperature—into one monitoring platform.

The sensor system combines constant-voltage and optical detection technologies with an optimized photoelectric receiving structure. Automatic temperature and light compensation help maintain measurement accuracy under changing operating conditions. A digital filtering algorithm further suppresses noise and other signal interference.

With standard Modbus digital communication, the monitor can be connected to external monitoring, control, and management platforms, making it suitable for centralized water quality management and remote monitoring applications.

Key Product Features

Measured Parameters

The five parameters can be monitored simultaneously through the integrated display system, providing a centralized view of current water quality conditions.

Detection Technology

The monitoring system combines constant-voltage detection and optical measurement principles according to the characteristics of the monitored parameters.

An optimized photoelectric receiving structure improves the collection of optical signals, while automatic temperature compensation helps reduce measurement deviations caused by temperature changes. Light compensation is also incorporated to improve measurement stability under different ambient lighting conditions.

The built-in digital filtering algorithm helps reduce the influence of noise and other electrical signal interference, supporting more stable data acquisition during continuous operation.

Display and User Interface

• 7-inch high-definition touchscreen

• Optional 10-inch high-resolution color touchscreen

• Chinese and English interface support

• Real-time display of monitored parameters

• Manual control functions

• Intuitive operating interface

The touchscreen provides centralized access to monitoring information and control functions, reducing the need for separate instruments for individual parameters.

Intelligent Dosing Control

The monitor can be configured with intelligent dosing control for automated water treatment operations.

A 5-way waterproof socket is provided for connection with corresponding dosing equipment. Based on configured control conditions, the system can assist with automated dosing management.

Intelligent dosing can reduce unnecessary water replacement and help lower operating and maintenance costs.

Remote Cloud Monitoring

The system supports online real-time monitoring through a cloud platform.

Users can remotely access current water quality information without being physically present at the installation site. This is particularly useful for distributed water treatment facilities and projects that require centralized monitoring.

Remote functions include:

• Real-time water quality viewing

• Cloud-based data management

• Remote monitoring

• Abnormal-condition notification

• Multi-site monitoring support

Network and Communication

The monitor provides multiple network connection options and reserves communication interfaces on the host controller for system integration.

A standard Modbus digital signal output enables connection with external monitoring or control platforms, allowing measured data to be incorporated into existing automation and water quality management systems.

The API can also be used to transmit relevant monitoring data to designated external platforms, including health supervision systems where required by the project.

Alarm and Notification Functions

The monitor provides configurable alarm functions for abnormal or out-of-limit water quality conditions.

Depending on the system configuration, notifications can be delivered through:

• SMS

• Email

• WeChat push notifications

This allows operators to identify abnormal water quality conditions promptly and take appropriate corrective action.

International Standard Support

The system provides selectable standard parameter configurations to accommodate different project requirements.

Supported standard configurations include:

• Chinese standards

• Russian standards

• EU standards

The applicable configuration can be selected according to the target market, project specification, and monitoring requirements.

Project Payment Reminder Function

A built-in project payment reminder function is available for project-based deployments.

The operating duration can be configured according to project requirements, providing an additional management function for equipment supplied under staged payment or project-based commercial arrangements.

Installation

The monitor is designed for straightforward wall-mounted installation.

Its integrated display and control architecture reduces the need for multiple separate monitoring devices, helping simplify installation and system management.

Measurement Accuracy and Signal Stability

The system uses high-precision signal acquisition and amplification circuits to process sensor signals.

Combined with temperature and light compensation and digital filtering, the measurement architecture is designed to provide stable and accurate monitoring during continuous operation.
