Calibration Procedure
For better accuracy, a frequent calibration of the meter is rec-
ommended. Moreover, the instrument should be calibrated:
a) when the pH electrode or the battery is replaced;
b) at least once a month;
c) after testing aggressive chemicals;
d) where extreme accuracy is required.
Preparation
• Pour small quantities of pH 7.01 (HI7007) and pH
4.01 (HI7004) solutions into two clean beakers.
• For accurate calibration use two beakers for each
solution: the first one for rinsing the electrode, the
second one for calibration.
• For accurate readings, use pH 7.01 (HI7007) and pH
4.01 (HI7004) if samples to be measured are acidic,
or pH 7.01 (HI7007) and pH 10.01 (HI7010) for
alkaline measurements.
• If calibration to NBS standards is required, use
pH 6.86 (HI7006) instead of pH 7.01 and pH 9.18
(HI7009) instead of pH 10.01.
Procedure
• Remove the protective cap from the electrode, rinse
and immerse it in pH 7.01 buffer and stir gently. Wait
a couple of minutes for the reading to stabilize.
• Measure the solution temperature with a HI98501,
e.g. 20 °C.
• Set the rotary knob to the °C position to display the
manual temperature setting and adjust the °C trimmer
until the LCD shows the measured temperature.
• Set the rotary knob to the pH position, wait for the
reading to stabilize and with a small screwdriver adjust
the AP trimmer until the LCD shows the pH value at
the above temperature (see pH vs. temperature chart
on the buffer bottle).
• Rinse and immerse pH electrode and thermometer in
pH 4.01 or pH 10.01 buffer (2
nd
calibration point); stir
gently.
• Wait a few minutes, then adjust the pH trimmer until
the LCD shows the pH value at the noted temperature
(see pH vs. temperature chart on the buffer bottle).
Operational Guide
• Slide off the battery compartment cover on the back
of the meter and install the supplied 9V battery, while
paying attention to its polarity.
• Connect the pH electrode to the BNC socket on the top
of the meter and remove the electrode protective cap.
• Immerse the electrode (at least 4 cm/1.5’’) and an
accurate thermometer (eg. HI98501) in the sample to
be tested, as close as possible one to the other.
• Turn the rotary knob to the °C position to display the
temperature setting. With the provided screwdriver,
adjust the °C trimmer to read on the LCD the
temperature measured by the thermometer.
• Turn the rotary knob to the pH position, shake the
electrode briefly and allow the reading to stabilize. The
display will show the pH value compensated for the
manually adjusted temperature.
• After measurements, switch the meter OFF by turning
the rotary knob to the OFF position, disconnect the
electrode from the meter and store it with a few drops
of HI70300 solution in the protective cap.
Notes:
Before taking measurements, make sure the meter is
calibrated.
If the electrode has been left dry, soak the tip in
HI70300 storage solution for at least one hour to
reactivate it.
For a faster response time when using refillable
electrodes, unscrew the refill hole cap.
• If measurements are taken in different samples
successively, it is recommended to clean the electrode
thoroughly to eliminate cross-contamination. After
cleaning, rinse the electrode with some of the sample
to be measured.
