Free Chlorine Analyzer

The LXT330FCA is a panel mounted, ready to use Free Chlorine Analyzer. It is designed to monitor free chlorine in seawater , drinking water, rinse water, cooling water or other fresh water samples from 0.05ppm to 20 ppm chlorine as the standard range or 0.01 to 5ppm with the low range sensor. The LXT330FCA is compliant with EPA method 334.0 for measuring drinking water.

The LXT330FCA features a plug and play design that incorporates a constant head flow control device, a pH sensor, a chlorine sensor and the LXT330 analyzer/transmitter  conveniently mounted on a PVC panel. Connect the sample and drain lines, connect the power and outputs and it is ready to use. Calibration is accomplished by DPD comparison.

Free chlorine exists in solution as a pH dependent ratio of hypochlorous acid  (~100% at  pH  5)  and  hypochlorite ion (~100% at pH 10). The Free Chlorine Sensor measures only the hypochlorous acid component of  the free chlorine and the analyzer calculates the balance using either the measured pH or a user defined fixed value. The use of the pH sensor provides accurate compensation for samples between pH 6 and pH 9 eliminating the need for expensive sample conditioning systems to control the pH of the solution.
