    Industrial Free-Chlorine Analyzer

Wherever free chlorine is measured to assure water purity, cleanliness or disinfection in hazardous industrial processes and plants, the FM/ATEX/IECEx approved Model FCX80 Free-Chlorine Analyzer from Electro-Chemical Devices (ECD), will help engineers and technicians get the job done in a safe manner. The Analyzer is certified for hazardous locations where combustible gases can be present in water treatment areas, helping prevent hazardous situations that could jeopardize employee safety, plant equipment and the surrounding area. This analyzer is designed for demanding applications, such as raw food processing rinse water, beverage pasteurization, cooling tower and boiler water scale prevention, pulp/paper bleaching operations, wastewater effluent treatment and much more.

Wide temperature range

The panel mounted FCX80 Analyzer is designed to monitor free chlorine in drinking water, rinse water, cooling water or other fresh water samples from 0.05 to 20 ppm chlorine as the standard range or 0.01-5.00 ppm with the optional low range sensor. With its intrinsically safe, explosion-proof barrier design, this analyzer’s Model S88 Free Chlorine Sensor provides accurate and reliable measurement via its advanced digital communications. The sensor’s no-reagent design features amperometric sensing based on polarographic technology relying on gold/silver materials and a PTFE membrane. The sensor operates over a wide temperature range from 0 to 50°C (32 to 122°F). Response time is T90 in 2 minutes. The only maintenance needed is replacing its economical electrolyte solution at intervals of up to 12 months. 

For ease of plant management, the FCX80 Analyzer is compatible with supervisory control and data acquisition (SCADA) systems or large distributed control systems (DCS), including a 4-20 ma output. The standard configuration features two 4-20 mA outputs, three single-pull/double-throw (SPDT) alarm relays and a MODBUS remote telemetry unit (RTU). Digital HART communications is also available.
