Note: For better accuracy, calibrate the meter
using a calibration solution at the same
temperature of the liquid to be measured.
If calibration is performed at a different
temperature, the error is approx.
0.0035pH for each 1°C difference multiplied by the difference between the pH
of the measured liquid and pH7;
e.g. meter calibrated at 25°C/measured
liquid: pH 4 / liquid temperature: 35°C;
the error is approx.:

TAKING REDOX MEASUREMENTS
To make correct redox measurements the
following conditions must prevail:
Redox measurements allow the quantification of the oxidizing or reducing power of a
solution, and are commonly expressed in
mV.
Oxidation may be defined as the process
during which a molecule (or an ion) loses
electrons and reduction as the process by
which electrons are gained.
Oxidation is always coupled together with
reduction so that as one element gets oxidized, the other automatically is reduced,
therefore the term oxidation-reduction is frequently used.
Redox potentials are measured by an electrode capable of absorbing or releasing electrons without causing a chemical reaction
with the elements with which it comes into
contact.
The electrodes most usually available for
this purpose have gold or platinum surfaces;
gold possesses a higher resistance than platinum in conditions of strong oxidation, while
platinum is preferred for the measurements
of oxidizing solutions containing halides and
for more general uses.
When a platinum electrode is immersed in
an oxidizing solution a monomolecular layer
of oxygen is developed on its surface. This
layer does not prevent the electrode from
functioning, but it increases the response
time. The opposite effect is obtained when
the platinum surface absorbs hydrogen in
the presence of reducing mediums. This phenomenon is rough on the electrode.
16
- The surface of the electrode must be
cleaned and smooth.
- The surface of the electrode must undergo a preventive treatment depending whether the solution to be measured has oxidizing or reductive characteristics.
Because the Pt/PtO system depends on the
pH, the pretreatment of the electrode may
be determined by the pH and the redox
potential of the solution to be measured.
As a general rule, if the ORP mV reading
corresponding to the pH solution value is
higher than the value in the Table below, an
oxidizing pre-treatment is necessary; otherwise a reducing pre-treatment is necessary:
pH m V pH mV pH mV pH mV pH m V
0 990 1 920 2 860 3 800 4 740
5 680 6 640 7 580 8 520 9 460
10 400 11 340 12 280 13 220 14 160
Reducing pre-treatment: immerse the electrode for a few minutes in HI 7091.
Oxidizing pre-treatment: immerse the electrode for a few minutes in HI 7092.
If pre-treatment is not performed, the electrode will take a significantly longer time to
respond.
When working with electrodes of the refilling type, the electrolyte used for filling must
be constantly kept at an adequate level (no
less than 2½ centimeters from the filling
hole) and topped up if necessary with HI 7071
refilling solution.
17
In the event that measurements are performed with solutions containing sulfides or
proteins, the cleaning of the diaphragm of
the reference electrode must be performed
(see page 21, "Cleaning Procedure").
ELECTRODE CONDITIONING
AND MAINTENANCE
In order to have a correct functioning of the
ORP electrode, immerse it into HI 7020 and
measure the response; the obtained value
should be within 200 and 275 mV.
After this functional test, it is suggested to
wash the electrode thoroughly with water
and proceed to the oxidizing or reducing
pre-treatment before taking measurements.
When not in use, the electrode tip should be
kept moist and far from any type of mechanical stress which might cause damage.
For this reason , the use of the protective
cap supplied with the electrode is advised.

PREPARATION
Remove the protective cap.
DO NOT BE ALARMED IF ANY SALT DE-
POSITS ARE PRESENT.
This is normal with electrodes and they will
disappear when rinsed with water.
During transport tiny bubbles of air may have
formed inside the glass bulb. The electrode
19
cannot function properly under these conditions. These bubbles can be removed by
"shaking down" the electrode as you would
do with a glass thermometer.
If the bulb and/or junction are dry, soak the
electrode in HI70300 Storage Solution for at
least one hour.
For refillable electrodes:
If the fill solution (electrolyte) is more than
1 cm (½") below the fill hole, add HI7082
3,5M KCl Electrolyte Solution for double
junction or HI7071 3,5M KCl+AgCl Electro-
lyte Solution for single junction electrodes.
For a faster response unscrew the fill hole
screw during measurements.
Follow the Preparation Procedure above before taking measurements.
Note: NEVER STORE THE ELECTRODE
IN DISTILLED WATER OR DRY.
PERIODIC MAINTENANCE
Inspect the electrode and the cable. The
cable used for the connection to the meter
must be intact and there must be no points
of broken insulation on the cable or cracks
on the electrode stem or bulb.
Connectors must be perfectly clean and dry.
If any scratches or cracks are present, replace the electrode. Rinse off any salt deposits with water.
For AmpHel® electrodes:
If the electrode does not respond to pH
changes, the battery is run down and the
electrode should be replaced.
MEASUREMENT
Rinse the electrode tip with distilled water.
Immerse the tip (4 cm / 1½") in the sample
and stir gently for approx. 30 seconds.
For a faster response and to avoid cross
contamination of the samples, rinse the electrode tip with a few drops of the solution to
be tested, before taking measurements.
STORAGE
To minimize clogging and assure a quick
response time, the glass bulb and the junction should be kept moist and not allowed to
dry out.
Replace the solution in the protective cap
with a few drops of HI 70300 Storage Solu-
tion or, in its absence, Filling Solution
(HI7071 for single junction or HI7082 for
double junction electrodes).

20
For refillable electrodes:
Refill the electrode with fresh electrolyte
(HI7071 for single junction or HI7082 for
double junction electrodes). Allow the electrode to stand upright for 1 hour.
Follow the Storage Procedure above.
CLEANING PROCEDURE
General
Soak in Hanna HI7061 Gen-
eral Cleaning Solution for approximately 1 hour.
Removal of films, dirt or deposits on the
membrane/junction:
Protein
Soak in Hanna HI7073 Protein
Cleaning Solution for 15 minutes.
Inorganic
Soak in Hanna HI7074 Inor-
ganic Cleaning Solution for 15
minutes.
Oil/grease
Rinse with Hanna HI7077 Oil
and Fat Cleaning Solution.
21
IMPORTANT: After performing any of the
cleaning procedures rinse the electrode thoroughly with distilled water, drain and refill
the reference chamber with fresh electrolyte, (not necessary for GEL filled electrodes)
and soak the electrode in HI 70300 Storage
Solution for at least 1 hour before taking
measurements.
TROUBLESHOOTING
Evaluate your electrode performance based
on the following.
• Noise (Readings fluctuate up and down)
could be due to:
- Clogged/Dirty Junction: Refer to the
Cleaning Procedure above.
- Loss of shielding due to low electro-
lyte level (in refillable electrodes only):
refill with HI7071 for single junction or
HI7082 for double junction electrodes.
• Dry Membrane/Junction: Soak in Stor-
age Solution HI70300 for at least 1 hour.
ter and then follow the Cleaning Procedure above.
• For ORP Electrodes: polish the metal
tip with a light abrasive paper (paying
attention not to scratch the surface) and
wash throughly with water.
• Drifting: Soak the electrode tip in warm
Hanna Solution HI7082 for one hour and
rinse tip with distilled water. Refill with
fresh HI7071 for single junction electrodes
and HI7082 for double junction electrodes.
• Low Slope: Refer to the cleaning proce-
dure above.
• No Slope: Check the electrode for cracks
in glass stem or bulb (replace the electrode if cracks are found).
• Slow Response/Excessive Drift: Soak
the tip in Hanna Solution HI7061 for 30
minutes, rinse thoroughly in distilled wa-

CORRELATION FOR HANNA
pH SENSITIVE GLASS
The resistance of glass electrodes partially
depends on the temperature. The lower the
temperature, the higher the resistance. It
takes longer time for the reading to stabilize
if the resistance is higher. In addition, the
response time will suffer to a greater degree
at temperatures below 10°C.

Since the resistance of the pH electrode is
in the range of 200 Mohm, the current across
the membrane is in the pico Ampere range.
Large currents can disturb the calibration of
the electrode for many hours.
Typical Electrode Life
Ambient Temperature 1- 3 years
90 °C Less than 4 months
120°C Less than 1 month
High concentrations of sodium ions interfere
with readings in alkaline solutions; the pH at
which the interference starts to be significant depends upon the composition of the
glass. This interference is the alkaline error
and causes the pH readings to be underestimated. Hanna's glass formulations have the
indicated characteristics.

For these reasons high humidity environ-
ments, short circuits and static discharges are detrimental for a stable pH
reading.
The pH electrode's life also depends on the
temperature. If constantly used at high temperatures, the electrode life is drastically
reduced.

SUGGESTED INSTALLATIONS
SHORT DISTANCE, INDOOR INSTALLATION
Due to the high impedance of the pH and
ORP electrode's glass membrane (usually
more than 100 MΩ), a very high grade of
insulation is required.

AmpHel® electrodes have a micro-amplifier
in the electrode cap to boost the signal,
drastically reducing susceptibility to noise
and drift.
With all of the components sealed in the
electrode body, moisture up to 100% RH
will not effect the signal.
MEDIUM DISTANCE,
INDOOR/OUTDOOR INSTALLATION
Since the introduction of AmpHel® these distances are no longer a problem. You are
now able to connect your meter directly to
an AmpHel® electrode, saving the cost of a
transmitter or costly coaxial cable.
The standard cable length of the AmpHel
electrode is 5 m (16.5'). Additional lengths
of regular cable up to 50 m (165'), can be
installed without special connectors.
