Probe Maintenance
To obtain the highest accuracy for measurements
it is important to follow these tips:
• Calibration is only as good as the buffers being used.
The pH buffers value change over time once the sachets
are opened. Fresh buffer should be used for each
• The probe should be rinsed with purified water each
time before pla cing in buffer or sample to be tested.
• When the meter is not in use it is important to add
several drops of storage solution to a sponge in the
protective cap to keep the probe hydrated. If storage
solution is not available, then pH 4.01 or pH 7.01 buffer
can be used.
• For improved accuracy it is recommended to calibrate
in two points. It is important to use buffers that bracket
the expected value of the sample to be tested. For
example, if the expected value is pH 8, the meter should
be calibrated using pH 7.01 and pH 10.01 buffers.
• It is important to calibrate and measure samples at the
same temperature. A dramatic change in temperature
between buffer solutions and samples to be tested will
give inaccurate readings.
Battery Replacement
When the battery becomes weak, the instrument
automatically switches the display off. It is recommended to
replace the battery immediately.
Replacement must only take place in a safe area using an
alkaline 9V battery. Remove the battery cover and replace
the old battery with a new one, while paying attention to
its polarity.
Note: After changing the battery, recalibrate the meter.
Recommendations for Users
Before using Hanna products, make sure that they are
entirely suitable for your specific application and for the
environment in which they are used. Operation of these
instruments may cause unacceptable interferences to
other electronic equipment. Take all necessary steps to
correct such interferences. Avoid touching the probe at
all times. Any variation introduced by the user to the
supplied equipment may degrade the instrument’s EMC
performance. Do not put the instrument in a microwave
oven to avoid burns or damage to equipment. Do not use
or store the instrument in hazardous environments.
This meter is warranted for two years against defects
in workmanship and materials when used for their
intended purpose and maintained according to instructions.
Electrodes are warranted for six months. This warranty is
limited to repair or replacement free of charge. Damage
due to accidents, misuse, tampering or lack of prescribed
maintenance are not covered. If service is required, contact
the dealer from whom you purchased the instrument.
If under warranty, report the model number, date of purchase, serial number and the nature of the problem. If the
repair is not covered by the warranty, you will be notified
of the charges incurred. If the instrument is to be returned
to Hanna Instruments, first obtain a Returned Goods Authorization Number from the Customer Service department and
then send it with shipment costs prepaid. When shipping
any instrument, make sure it is properly packaged for
complete protection.
Hanna Instruments reserves the right to modify the design,
construction, or appearance of its products without advance notice.

For better accuracy, a frequent calibration of the meter is recommended. 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.
• 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.
• 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 (2nd calibration point); stir
• 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.
Before taking measurements, make sure the meter is
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.
