Aseko - Free Chlorine Probe (CLF)

Aseko Free Chlorine Probe (CLF) – Direct Chlorine Sensor

The Aseko Free Chlorine Probe (CLF) is a high-precision amperometric sensor that directly measures the concentration of free chlorine (hypochlorous acid) in pool water. Unlike ORP sensors, the CLF probe provides an actual chlorine value in mg/L (ppm), enabling the Aseko ASIN Aqua PRO system to dose with exceptional accuracy.

Direct free chlorine measurement is the gold standard for professional pool water management, eliminating the uncertainty of indirect ORP readings. The CLF probe ensures the pool maintains safe, effective chlorine levels at all times regardless of pH fluctuations or temperature changes.
