Water Quality

Self-cleaning fiber optic turbidity sensor with 90° scattered light detection — 0~4000 NTU, RS-485 / Modbus, IP68, for long-term online water quality monitoring.
The self-cleaning turbidity sensor applies optical fiber technology to the turbidity sensor, and the principle of scattered light detection at a 90° angle has better repeatability and stability, and is not easily affected by ambient light. The automatic cleaning brush with the sensor can effectively eliminate air bubbles and reduce the influence of dirt on the measurement. It has a longer maintenance period and maintains excellent stability for long-term online use.
