PHH-60 and PHH-80
pH/Conductivity Meter
Overrange conductivity is indicated by
“1” on the display.
4. Calibrate the meter before using the
instrument. Refer to the previous
section.
5. Immerse electrodes in solution to be
measured. For proper operation,
immerse electrodes to half their
length.
6. Agitate electrodes briefly (to mix the
sample) and observe the reading.
7. To change parameters, press the
pH/µS switch one time. The range
sequence on the PHH-80 is
pH-200K-20K-2K.
8. Rinse the electrodes thoroughly and
replace pH soaker bottle and
conductivity cover before folding
into storage compartment (at the
back); fill the bottle with a small
amount of pH4 buffer or pH7 buffer.
9. Remove the battery when the
instrument is to be stored for a long
period of time.
pH Electrode Care
pH Electrodes must be kept moist
. The
pH electrode was shipped stored in a
soaker storage bottle. The storage
solution contained in the bottle is a
potassium chloride solution. Do not be
alarmed if white crystals form at the end
of the electrode. It is simply potassium
chloride. Rinse with distilled water to
dissolve the crystals before using the
electrode.
For storage, place the electrode back in
the soaker bottle.
If the potassium
chloride solution evaporates or is lost,
simply use pH buffer 4.0 or pH buffer 7.0
supplied for storage. DO NOT use
distilled or deionized water as this will
drastically reduce the electrode lifespan.
