Analytical Technology B20 Residual Chlorine Recorder0 pages
Residual Chlorine Recorder .......
Introduction
Providing permanent chlorine residual records normally means purchasing
a residual chlorine monitor and connecting the output of the monitor to a
separate recorder. ATI’s B20 provides an integrated solution to this problem,
combining both the analyzer and recorder functions in a single package.
This means simpler installation, easier operation, and lower cost. And
best of all, the system uses our direct measuring membraned sensor for reliable
measurement with minimal maintenance.

Series B20
Sensor and Flowcell
Series B20 chlorine recorders use the same reliable chlorine sensor
supplied for years as part of our Series A15 monitoring systems. The
sensor is a direct measuring polarographic membraned sensor that
eliminates the need for chemical buffers and other 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.
