Key Features & Advantages

90° Infrared Measurement

Uses 90° infrared scattering to measure suspended particles, supporting consistent turbidity monitoring in varied water-quality applications.

0.01-400 NTU Measuring Range

Measures from 0.01 to 400 NTU with ±5% F.S. accuracy, covering low-turbidity water and wastewater duties.

IP68 Rugged Construction

POM and 316 stainless-steel construction with IP68 sealing protects the sensor in submerged field and process installations.

Flexible Process Installation

Supports immersed, threaded and flow-through arrangements, allowing deployment in tanks, channels, pipelines and sampling systems.

Stable Modbus Transmission

Digital Modbus output resists interference, maintains stable signals and supports long-distance transmission to remote monitoring and control systems.
