ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.


CM-230s conductivity meter is an upgrade of the old CM-230, is an economic intelligent industrial online conductivity meter
1. full range (0~20/200/2000) automatic switching, intelligent digital temperature compensation;
2. display unit can be changed: uS/cm or ppm
3. conductivity & temperature can be displayed on the same screen


This series instruments are widely used for online pH/ORP monitoring in environment protection water treatment, pure water treatment, industrial process and so on.


Digital Laser Turbidity online analysis sensor,It can be used for on-line monitoring of water quality in different water bodies such as waterworks and membrane filtrate,The sensor internally completes all measurement calculation compensation


Measure range :TUR-6101 (0~5NTU) ;TUR-6102 (0~100NTU)


Single stage RO controller used for conductivity monitoring and process program control .
