Continuous water quality monitoring of Residual Chlorine

Providing permanent chlorine residual records normally means purchasing a residual chlorine monitor and connecting the output of the monitor to a separate recorder. The B20 Chlorine Recorder uses ATi’s industry-leading, reliable and accurate chlorine sensor, which is a direct measuring polarographic membraned sensor that eliminates the need for chemical buffers and reagents.

Sensors are available for Free Chlorine measurements or for Combined Chlorine monitoring, where Chloramine treatment is in use. Chlorine sensors require a constant sample flow past the membrane to provide stable and accurate readings. B20 systems are supplied with a constant-head flowcell assembly that automatically maintains the desired flow.  Hose barbs for sample inlet and drain provide for connection of flexible PVC tubing.
