Residual Chlorine

Our Residual chlorine include the CL7685, based on potentiostatic principal which uses 2 platinum bands and a reference half cell which responds to Chlorine, Bromine, Chlorine Dioxide and Ozone providing a direct readout in ppm. We also are able to supply model LCL with a traditional amperomertric cell with copper and platinum electrodes and model LDCL which uses an amperomertric type cell with a membrane We also offer a portable chlorine meter with a direct readout , ideal for checking the calibration of the on line instruments.

Applications include measurement of potable waters from water treatment plants, swimming pool waters and borehole waters used for potable or industrial use.
