I. Product Overview

The turbidity analyzer is an online monitoring instrument designed to measure the suspended solids concentration of municipal sewage and industrial wastewater. It can be used to monitor turbidity changes during biological treatment and provides continuous and accurate results. The innovative multi-beam mutual compensation technology eliminates the measurement error caused by fouling of the sensor optical window, which noticeably improves accuracy, reduces maintenance work and increases reliability.

II. Key Features

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

2. High-precision 24-bit ADC signal acquisition 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. Optional upper-computer online acquisition software from our company for data acquisition and analysis.

5. One-key calibration with standard solution; built-in watchdog with data retention exceeding 10 years after power failure.

6. Dual-relay upper and lower limit alarm output.

7. The sensor is temperature-compensated, which corrects the influence of temperature on the measured value.

8. Special functional requirements can be customised.
