The replacement membrane for the CLF (free chlorine) probe with a diameter of 80 mm separates the measured water from the measuring electrodes and electrolyte, thereby protecting the sensitive parts of the sensor from contamination.
The membrane is extremely sensitive to mechanical damage — never apply pressure to it or clean it mechanically with abrasive agents.
Rinse it solely under a stream of cold clean water, or in the acid designated for cleaning membranes.
The use of unsuitable caustics or incorrect acids is strictly prohibited, as it would cause irreversible damage to the membrane and probe.
Regular replacement of the membrane is essential for maintaining measurement accuracy and the correct operation of automatic pool water treatment.
