Turbidity detector

Introduction:

Hengmei’s new optical turbidity sensor, fiber optic sensing technology, adopts the 90° scattered light measurement principle, complies with ISO7027 international standards, customized optical devices, small size, easy installation and maintenance, not easily disturbed by ambient light, and has better repeatability and stability. Make turbidity measurement more accurate, more stable, faster and more convenient.

With backlit display and operation keyboard, comprehensive functions and simple operation, simple interface, automatic recognition of turbidity fiber optic sensor, reading and storage of measurement data, sensor calibration and other functions, and USB data export to achieve more high-end functions. The pursuit of high cost performance is our consistent pursuit.

It has a wide range of applications and can be used for water quality detection in multiple scenarios such as surface water, sewage, seawater, tap water, etc. to meet customer needs.
