ROC-8221 Single Stage Double Channels RO Controller
ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.

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

Meter, time clock dual mode. In flow mode, the internal flow transmitter realizes the function of setting water volume as required. After setting regeneration water volume and cleaning water volume of exchange tank, the period of softening water amount (ton) according to the hardness of the raw water, each station decreases to “0” according to the set value, and stops decreasing and maintains when the water is out of service or no water.


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

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

Flexible 7 or 12 day time clock or meter initiated regeneration
Fully adjustable, 5-cycle control delivers upflow back wash, downflow brining, slow rinse, rapid rinse and down flow service
Designed for single tank or multi-tank systems, alternating or interlocking
Continuous flow rate of 250 GPM


Fluorescence quenching principle, no need for internal filling, no oxygen consumption, and easy maintenance;
The service life of the fluorescent membrane cap is more than one year (under ideal conditions);
Original altitude, atmospheric oxygen partial pressure, temperature compensation, to improve the authenticity of the data;

Salt and water savings by using 100% capacity of the tank in service before switching to the second tank
Regenerates immediately when needed for continuous soft water
Corrosion-free fiber-reinforced polymer valve body
