Overview

Optical turbidity sensor uses the 90° scattering light method to monitor water cleanliness and suspended particulate matter content, with a measurement range of 0~1000 NTU and an accuracy of ±5%. SUCH turbidity sensor has an IP68 protection rating and supports RS485 (MODBUS) communication for easy integration with various monitoring systems. The turbidity sensor can operate normally under conditions of 0~50℃ and a maximum pressure of 5 bar, with a power supply range of DC 9~24V and an operating current of less than 50mA, making it suitable for water treatment, environmental monitoring, and various industrial applications.

Feature

Uses custom quartz optical components with a compact, durable design for easy installation and maintenance.
Requires no reagents, offering zero pollution, long service life, and low operating cost for an eco-friendly solution.
Supports standard Modbus protocol with built-in calibration parameters and precise factory calibration.

optical turbidity sensor works as expected

I use this optical turbidity sensor in my water monitoring setup. The installation process was simple, and the readings look consistent during normal use. The first few days I spent some time checking the data and cleaning the sensor, but that is expected with this type of product. Overall, it works well and does what I need.
