Accessories
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.
Recommendations for Users
IST8010V 06/16
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
calibration.
• 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.
Probe Maintenance

Portable pH Meter
Hanna Instruments reserves the right to modify the design,
construction, or appearance of its products without advance notice.
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.
Warranty
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 pur-
chase, 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 Autho-
rization 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.
