Chlorine sensor launch

5th April 2018


Designed with polarographic technology, the FC80 Free Chlorine Sensor from Electro-Chemical Devices eliminates the need for expensive reagents while providing highly accurate free chlorine measurement performance.

The advanced FC80 Free Chlorine Sensor monitors free chlorine in municipal drinking water from 0.05 – 20 ppm chlorine as the standard range or 0.01 - 5.00 ppm with the low range sensor. The FC80 is compliant with EPA Method 334.0 for measuring drinking water. It also supports a wide variety of industrial process and plant applications including rinse water, cooling water or other fresh water sampling tasks.

It includes digital communication capabilities and features amperometric sensing based on polarographic technology relying on gold/silver materials and a PTFE membrane. It 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 required is the replacement of its economical electrolyte solution at intervals of up to 12 months.

Free chlorine for disinfection applications exists in solution as a pH dependent ratio of hypochlorous acid (~100% at pH 5) and hypochlorite ion (~100% at pH 10). Chlorine has been a popular disinfectant for water treatment to ensure public health. Disease causing organisms such as Cholera, Hepatitis A, Typhoid Fever and Dysentery are eliminated with Chlorine, along with slime bacteria, algae and moulds that can grow in water storage facilities such as reservoirs and storage tanks.
