PMH-2 and SWIMMING POOLS.
Maintaining a swimming pool with PMH-2 controllers is simple and cost
effective.
(Fig.11)
The PMH-2 monitoring a metal electrode controls the
liquid chlorine for the pool. Chlorine is a caustic liquid and increases the
pH level when added to the pool water. The PMH-2 connected to a pH
electrode maintains pH at 7.2 to 7.6 by dosing acidic neutraliser. The
electrodes are installed in a drain configuration, drawing off a small
amount of pool water. This method has proved to work better than a
conventional by-pass installation.
