OPERATIONAL GUIDE
pH ELECTRODE
• Any combination pH electrode provided with a BNC
connector can be attached to the controller.
See our General Catalog for a complete range of Hanna
pH electrodes.
• Do not be alarmed if white crystals appear around the
electrode protective cap. This is normal with pH elec-
trodes and they dissolve when rinsed with water.
• When not in use, rinse the electrode with water and
store it with a few drops of storage (HI 70300) solution
in the protective cap.
NEVER USE DISTILLED OR DEIONIZED WATER FOR STOR-
AGE PURPOSES.
• If the electrode has been left dry, soak the tip in a
storage (HI 70300) or pH 7 (HI 7007) solution for at
least one hour to reactivate it.
• To minimize clogging and provide longer life for the pH
electrode, it is recommended to clean it monthly.
Immerse the tip of the electrode in the HI 7061 solution
for half an hour, then rinse it with tap water.

HI 981400 is a pH indicator specially designed for pH
control in foodstuffs.
The pH value is one of the most important indicators of food
quality and safety. pH of raw ingredients, such as milk and
meat, is measured to ensure the quality standards of
products. pH is also monitored at different stages of food
processing to guarantee safety and enhance quality.
HI 981400 is also provided with a flashing LED that
indicates if the measured pH exceeds the selected limit.
Hanna Instruments offers several pH electrodes specially
designed for the food industry, such as the FC 200B with
open junction, and the FC 230B with stainless steel blade
for direct meat measurement.
Thanks to the built-in hook, the meter can b easily hanged
right above the sample for continuous monitoring.
The meter can be calibrated at one or two points.
You no longer need to worry about battery changes because
the unit runs without interruption on 12 Vdc power supply.
