The YST909B-CH980 equipment from Dalian Yister has been running continuously for more than a year with strong stability, small deviation between data and laboratory testing, and automatic cleaning function that reduces 80% of manual maintenance workload. The effluent compliance rate has increased from 95% to 99.8%

A technician from a certain water supply plant said: "The residual chlorine data of the YST909B-CH980 model can be uploaded to the smart water management platform in real time, accurately capturing the decay law of residual chlorine in the pipeline network. The disinfection dosage is more reasonable, which not only ensures water supply safety but also saves drug costs. ”

Logistics management personnel of a certain hospital: "The composition of medical wastewater is complex, and the anti-interference ability of Dalian Yister's YST909B-CH980 model exceeds expectations. The residual chlorine monitoring data is accurate and stable, meeting the strict requirements for medical wastewater discharge. ”

The person in charge of a smart rural water project: "The YST909B-CH980 model is small in size, easy to install, supports solar energy and 4G transmission, and can also achieve real-time monitoring of water supply points in remote towns. The compliance rate of residual chlorine in rural drinking water has been greatly improved. ”

A certain chemical wastewater treatment engineer said: "The monitoring effect of YST909B-CH980 model on high salt wastewater is very ideal, with stable data accuracy, which helps us optimize the disinfection process and save about 300000 yuan in annual drug costs. ”
