Introduction to turbidity sensor
The online turbidity analyzer is a patented product with independent intellectual property rights developed specifically for online monitoring of drinking water quality. It has the characteristics of ultra-low turbidity detection limit, high-precision measurement, long-term maintenance free equipment, water-saving work, and digital output. It supports cloud platform and mobile data remote monitoring, as well as RS485 Modbus communication. It can be widely used in turbidity online monitoring scenarios such as water plant inlet and outlet, secondary water supply, pipe network end water, direct drinking water, membrane filtered water, swimming pools, and surface water.
Sensor features:
The online turbidity analyzer adopts the standard 90 ° scattering method detection principle, self-developed optical path and detection structure, and real-time compensation algorithm to achieve high-precision turbidity measurement;
The sensor comes with a cleaning brush, which can effectively clean the light window and meet the long-term stable online monitoring needs;
Our self-developed defoaming and measuring unit effectively eliminates water bubbles, ensures water stability, and further improves measurement accuracy.
