D. Cleaning Sensors
1. Conductivity/TDS/MIN
/
SALT
The conductivity cell cup should be kept as clean as possible. Flushing
with clean water following use will prevent buildup on electrodes.
However, if very dirty samples — particularly scaling types — are
allowed to dry in the cell cup, a film will form. This film reduces accuracy.
When there are visible films of oil, dirt, or scale in the cell cup or on the
electrodes, use isopropyl alcohol or a foaming non-abrasive household
cleaner. Rinse out the cleaner and your P
ool
P
ro
is ready for accurate
measurements.
2. pH/ORP
The unique pH/ORP sensor in your P
ool
P
ro
is a nonrefillable
combination type that features a porous liquid junction (see Figure 29).
It should not be allowed to dry out. If it does, the sensor may sometimes
be rejuvenated by first cleaning the sensor well with Isopropyl alcohol or
a liquid spray cleaner such as Windex™ or Fantastic™ and rinsing well.
Do not scrub or wipe the pH/ORP sensor.
Then use one of the following methods:
1. Pour a HOT salt solution ~60°C/140°F, preferably potassium
chloride (KCI) solution (Myron L pH/ORP Sensor Storage
Solution) — HOT tap water with table salt (NaCl) will work fine
— in the sensor well and allow to cool. Retest.
or
2. Pour DI water in the sensor well and allow to stand for no more
