USER MANUAL
PORTABLE
pH METER
MODEL: MW100

OPERATION:
• The meter is supplied complete with a
9V battery. Slide off the battery
compartment cover on the back of the
meter. Install the battery into the battery
clip connector while observing polarity.
• Always remove the electrode
protective cap before taking any
measurement. If the electrode has been
left dry, soak the tip (bottom 2.5 cm) in
rinse solution (M10000B) for a few
minutes to reactivate it.
• Connect the pH electrode to the BNC socket on the top of
the meter.
• Make sure that the meter has been calibrated before taking
any measurements (see Calibration Procedure).
• Immerse the tip (2.5 cm) of the pH electrode into the sample.
• Turn the instrument on by pressing the ON/OFF key.
• Allow the reading to stabilize before taking measurements.
• After measurements, switch the meter off and store the
electrode with a few drops of storage solution
(MA9015) in the protective cap.
CALIBRATION PROCEDURE:
• Remove the protective cap from the electrode.
• Rinse tip off with distilled water or a small
quantity of pH 7.
• Immerse the electrode tip into a new sachet
of pH7 calibration solution and allow the reading
to stabilize.
• Adjust the pH7 (OFFSET) calibration trimmer to
display "7.0 pH".
• Open a new sachet of pH4 calibration solution
and use a small quantity to rinse the electrode.
• Immerse the electrode tip inside the pH4 sachet
and allow the reading to stabilize.
• Adjust the pH4/pH10 (SLOPE) calibration
trimmer to read "4.0 pH".
• The calibration is now complete and the
meter is ready to take measurements.
• It is suggested the meter be calibrated at least
once a month, after a prolonged period of
inactivity, and after electrode replacement.
BATTERY REPLACEMENT:
When the battery becomes weak the meter
will display " ".
When the low battery indicator appears, the
battery has only about 50 hours of working
time left. A low battery will result in
unreliable measurements.
Prompt battery replacement is required.
Battery replacement must only take place in
a non-hazardous area using an alkaline 9V
battery.
Turn the meter off, slide the battery
compartment cover located at the rear of the
meter off and replace the 9V battery with a
new one. Make sure the battery contacts are fully engaged in
the connector, seat the battery in its compartment and replace
the cover.
