The main advantage of this operating choice is to guarantee in all cases (even in the case of a power
failure) the same normal or reverse production times and, as a result, to ensure the est possi le
descaling of the cell (enhancing production quality and equipment dura ility).
PH REGULATION
pH or the potential Hydrogen measures the degree of acidity of the water. Its value is etween 0 and
14. A solution whose pH is equal to 7 is neutral. If it is less than 7, the solution is acid and if it is
greater than 7, the solution is said to e a ase or alkaline solution.
For ather comfort, treatment efficiency and installation relia ility, the pH of the pool water must e
maintained around 7.
A pH etween 6.8 and 7.6 is generally considered to e correct.
A water which is too acid (pH <6.8) is aggressive for
mucosae, favours the corrosion of metal parts and can
damage plastics (liners).
A water which is too ase (pH>7.8) can also e
aggressive (caustic) and significantly reduce the
efficiency of chlorine. Thus, when the pH increases
from 7.2 to 8.2, the percentage of active chlorine
decreases from 70% to 20%.
In addition, pH has systematically a tendency to
increase due to the presence of salt in the water,
making pH regulation particularly useful.
To o tain the est treatment efficiency, it is therefore indispensa le to maintain the pH of the water
etween 7.0 and 7.6.
For information, the ta le to the right allows
determining the required production time
versus the asin volume, the pH for a water
temperature of 25°C.
Since the water temperature varies during the
season, the filtration time has to e adjusted
to increase production when the water
temperature rises and to decrease production
when the temperature drops.
To avoid any possi le measurement errors, it is recommended to check the calibration of the
probe once a month. To do this, simply follow the instructions in the CALIBRATION section.
EQUIPMENT DESCRIPTION
ELECTROLYSIS CELL FLOW DETECTOR PH PROBE
Your system’s essential element,
the cell, is equipped with solid
plates made of titanium treated
with ruthenium oxide. It is specially
designed to offer a maximum
service life and to limit
maintenance operations.
The flow detector delivered
with
Limpido EZ Duo
prevents the electrolyser
from operating in the
a sence of flow or during a
ackwashing. It prevents
any risk of hydrogen
accumulation or excessive
heating and thus reinforces
the device’s safety.
The pH pro e is made up of
electrodes which apply a voltage
proportional to the water’s pH. The
pH pro e is fragile and must e
carefully handled. It must e kept
immersed in an aqueous solution.
