GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
HACCP Food Stability pH Indicator is an indicator specially
designed to check pH in foodstuff.
The pH value ranks as one of the most important indicators
of food quality and safety. pH of raw ingredients such as
milk and meat is measured to ensure that quality standards
have been properly met. pH is also monitored at different
stages of food preparation and transformation to guarantee
safety, improve production and enhance quality.

HI 981400 measures and displays the pH value on a
HI 981400HI 981400
liquid cristal display. In addition, a flashing LED will
indicate if the measured pH exceeds the selected limit.
The HANNA range of electrodes includes some models specially made for the food sector, such as
open junction and

mended for meat measurement.
With a built-in hook, you can simply hang the meter right
above the sample to be tested for repetitive measurements.
The meter can be calibrated at one or two points.
You no longer need to worry about battery changes either: the
unit runs without interruption on 12 VDC power supply.

pH ELECTRODE MAINTENANCE
• Any combination pH electrode ending in a BNC connector can be attached to the controller. Choose from the
vast range of HANNA electrodes by consulting our
general catalog.
• Do not be alarmed if white crystals appear around the
electrode protective cap. This is normal with pH electrodes and they dissolve when rinsed with water.
• When not in use, rinse the electrode with water to
minimize contamination and store it with a few drops of
storage (HI 70300) or pH 7 (HI 7007) solution in the
protective cap. Always replace the protective cap after
use.
DO NOT USE DISTILLED OR DEIONIZED WATER FOR
STORAGE 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 at least once o
month. Immerse the tip of the electrode in HI 7061 for
half an hour and then rinse it with tap water.
