2. PUMP DESCRIPTION
The Henden pH Dosing Pump is characterised by its ability
to measure pH value (between 0 and 14) with its probe
placed on the filtration system that analyses the pool water.
Depending of the measured value, the pump will inject
the required amount of product needed to maintain the
balance of the pool water.
The pump works in acid (pH-) or basic (pH+) dosage.
