1. Small size, convenient for system integration


2. Less water consumption, saving daily operating costs


3. It still maintains high accuracy in the low range and can be applied to the turbidity measurement of drinking water after membrane water purification


4. Long maintenance cycle, automatic sewage discharge, saving daily operation and maintenance costs


The ZDYG-2088 turbidity meter adopts the 90°scattering detection principle, and designs a unique photoelectric receiving structure, as well as an automatic temperature and light compensation method, which greatly improves the accuracy and accuracy of turbidity detection. The sensor has a built-in ARM7 data processor and uses an efficient digital filtering algorithm to avoid noise interference. At the same time, it uses standard Modbus digital signal output and 4-20mA analog output, which is convenient for users to access the computer monitoring system.

This product is a low-range turbidity detection device, mainly used for turbidity monitoring of purified water, swimming pool water, tap water and factory water, municipal pipe networks and peripheral water. The ZDYG-2088 turbidity meter is for online monitoring of drinking water quality. It has the characteristics of ultra-low turbidity detection limit, high-precision measurement, maintenance-free equipment, ultra-saving water work and digital output. It can be widely used in direct drinking water, Turbidity monitoring of membrane filtered water, tap water and pipe network water.
