FCA-220 Free Chlorine Analyzer
The reagentless FCA-220 combines Teledyne Analytical's field-proven LXT-220 line-powered controller, pH and chlorine ion electrodes to create a compensated free chlorine measurement independent of pH and flow rate.
The analyzer consists of the LXT-220 controller, probe receptacles and flow-control device mounted to an integrated panel for backplate mounting. Free chlorine exists as a pH-dependent ratio of hypochlorous acid and hypochlorite ion. The free chlorine sensor detects the hypochlorous acid component and calculates the hypochlorite ion level by pH level up to about 9.5 (above which all chlorine exists as hypochlorite ion). No sample conditioning with reagents is required to control pH.
The LXT-220 controller is weatherproof NEMA-4X ½ DIN form factor mounted to the panel. The membrane keypad and backlit LCD display provides an easy-to-use interface with menu-driven functionality. 4-20mA output is provided as standard and configurable alarm contacts can be provided optionally.
