Describe the product: The ECD Model FC80 Free Chlorine analyzer is designed to measure the concentration of Free Chlorine in drinking water, industrial cooling water, rinse water or other samples of fresh water that use chlorine in the range of 0-20 ppm as a disinfectant. Chlorine exists in water as a pH dependent mixture of hypochlorous acid and hypochlorite ion. The sum of these two components is referred to as Free Chlorine, sometimes Residual Free Chlorine.

The FC80 is a complete system for measuring Free Chlorine. The panel mounted system includes a Constant Head Flow Controller (#1), Free Chlorine sensor (#3) and Flow Cell, pH sensor (#2) and Flow Cell, Spray Cleaner (#5)and the T80 Transmitter (#4). Simply supply power to the T80 Transmitter and plumb the sample line in and the drain line out and the FC80 is ready to use.

The CHFC maintains a constant sample flow to the pH and Chlorine flow cells. Pressure regulators and rotameters are not needed to maintain a constant flow rate, the CHFC provides trouble free sample conditioning between 10 and 80 gal/hr.

The Free Chlorine Sensor (FCS) is an amperometric sensor with a PTFE membrane, gold cathode and a silver/silver chloride anode. 

The T80 analyzer applies a fixed voltage across the chlorine electrode and measures the current flow. Hypochlorous acid (HOCl) diffuses through the PTFE membrane and is reduced (gains electrons) by the gold cathode to chloride ion. Silver on the anode is oxidized (donates electrons) to silver chloride completing the current loop. With stable temperature and sample flow, the current flow is proportional to the free chlorine concentration.

Many competitive chlorine sensors require service on a monthly or bimonthly basis. The FCS uses a large surface area anode, combined with a large volume of electrolyte and a small cathode to provide operational cycles of up to a year without refilling.

The replaceable PTFE membrane is also designed for long term stability. A special support grid maintains a constant tension between membrane and the cathode minimizing effects caused by varying pressures and flow. Replacing the PTFE membrane and recharging the electrolyte is easily accomplished without the use of tools.

The Model T80 transmitter can be 24 VDC powered or 100-240 VAC line powered. The standard configuration has two 4-20 mA outputs, an RS485 serial communication port with MODBUS®RTU and 3 Alarm relays.
