Free Chlorine Meters

Residual Chlorine or Free Chlorine is the measure of the amout of available Chlorine remaining in a system after the chlorine demand has been sastisifred.

Our Residual chlorine instruments include the CL7685. This Free Chlorine meter is based on the 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.

Another of the Residual Chlorine Instruments we are able to supply includes model CL7635 with a traditional amperomertric cell with copper and platinum electrodes and model BC7635 which uses an amperomertric type cell with a membrane.

We also offer a portable "Free 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.
