OPERATIONAL GUIDE

pH ELECTRODE MAINTENANCE

• Any combination pH electrode ending in a BNC connec-

tor 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 elec-
trodes 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.

Note: Conserve all packing material until the instrument

has been observed to function correctly. Any defective
item must be returned in its original packing.

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

HI 981400

HI 981400 measures and displays the pH value on a
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 spe-
cially made for the food sector, such as FC 200B

FC 200B

FC 200B with an

open junction and FC 230B

FC 230B

FC 230B with a cutting blade recom-

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.
