Potentiostatic free chlorine probe Seko KP-FCL

Free chlorine is the chlorine present in water in the form of hypochlorous acid (HOCl) or hypochlorite ion (OCl-). Its measurement ensures the amount of chlorine available for disinfection or purification purposes. The most robust and reliable measurement technique is the use of a potentiostatic free chlorine sensor.

In fact, when chlorine is added to water, it reacts with the organic compounds and metals present in the liquid, forming combined chlorine. Combined chlorine is not active for disinfection.

SEKO's Kontrol Probe range of chlorine probes covers most major water treatment applications.

Potentiostatic free chlorine probe Seko KP-FCL

The Seko model KP-FCL is a sealed cell free chlorine probe with selective membrane, 4 - 20 mA output and automatic temperature compensation. It has guaranteed accuracy, with a short response time due to active amperometric measurement.

Suitable for the measurement of inorganic free chlorine, the Seko KP-FCL probe has a reduced pH dependence. It is compatible with the presence of iso-cyanuric acid, surfactants and flocculants.

Thanks to the latest generation of membranes, these probes have excellent reliability even in dirty water and excellent measurement stability in the event of variations in flow rate.

Sectors of application:

• Drinking water
• Swimming pools
• Waste water
• Process water
• Seawater
