Please ensure that you keep the storage area of the acid well ventilated and ensure you use a suitable container with 
resistance to Hydrochloric Acid. 

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.
