I. Product Overview

The multi-parameter water quality online analyzer is a conventional five-parameter water quality monitor. The five conventional parameters are pH, temperature, dissolved oxygen, conductivity and turbidity. The monitor uses a modular design: the analyzer controller is connected to pH, dissolved oxygen, conductivity and turbidity sensors. The five conventional parameters directly and comprehensively reflect the degree to which a water body is polluted by organic and inorganic substances as well as some of its physical indicators, and they are also listed as mandatory items in the monitoring programmes of the national environmental protection authorities.

II. Key Features

1. TFT colour screen with a Chinese interface, making operation simple and convenient.

2. Imported TI chip and anti-interference circuit for higher precision and greater stability.

3. Photoelectrically isolated 4–20 mA current output and RS-485 / RS-232 communication interface.

4. Adjustable hysteresis (dead band) prevents the relay from switching too frequently.

5. Built-in watchdog; data retention after power failure exceeds 10 years.

6. 24-hour real-time online monitoring; IoT access for viewing, analysis and report generation.

7. Sensors with built-in temperature compensation.

8. Centralised acquisition and centralised measurement for convenient observation.

9. Replaces several separate instruments, reducing field wiring, instrument boxes and mounting brackets; small footprint and lower cost.

10. Special functional requirements can be customised.
