pH

MEASUREMENTS

Make sure the electrode and the instrument have been

calibrated together before taking pH measurements.
Submerge the electrode and the temperature
probe approximately 4 cm (1) into the sample
to be tested and stir gently. Allow time for the
electrode to stabilize.
The pH is displayed on the primary LCD and the temperature on
the secondary LCD.
pH
C

If the pH reading is out of range, ---- will be displayed on the

LCD.
6

If measurements are taken successively in different samples, it is

recommended to rinse the electrode thoroughly with deionized water
or tap water and then with some of the next sample in order to
prevent cross-contamination.
The pH reading is affected by temperature. In order to measure the
pH accurately, the temperature effect must be compensated for.
To use the Automatic Temperature Compensation feature, connect
and submerge the HI 7662 temperature probe into the sample as
close as possible to the electrode and wait for a few seconds.
If the temperature of the sample is known, manual temperature
compensation can be performed by disconnecting the temperature probe.
The display will then show the default temperature
of 25 C or the last recorded temperature reading
with the C tag blinking. The temperature can now
be adjusted with the ARROW keys (from -9.9 C to
120.0 C).

TEMPERATURE MEASUREMENTS
Connect the HI 7662 temperature probe to the TEMP
socket and turn the instrument on.
Immerse the temperature probe into the sample and
allow the reading on the secondary LCD to stabilize.
MEMORY FUNCTION
Press and hold down MEM. The last reading will appear on the LCD
along with MEM tag until MEM is released.

Press MR and the previously memorized reading will be displayed

with MEM tag on the LCD.

ORP MEASUREMENTS (H
211 only
(HII 222
only))
An optional ORP electrode must be used to perform ORP measurements
(see Accessories).
Oxidation-reduction potential (REDOX) measurements provide the
quantification of the oxidizing or reducing power of the tested sample.
To correctly perform a redox measurement, the surface
of the ORP electrode must be clean and smooth.
Press RANGE to enter mV range.
Submerge the tip of the ORP electrode 4 cm
(1") into the sample to be tested and allow a
few seconds for the reading to stabilize.
The instrument displays the mV reading on the primary LCD and
the temperature on the secondary LCD.
C

p H CALIBRATION
Calibrate the instrument often, especially if high accuracy is required.
The instrument should be recalibrated:
Whenever the pH electrode is replaced.
At least once a week.
After testing aggressive chemicals.
PREPARATION
Pour small quantities of the buffer solutions into clean beakers. If
possible use plastic or glass beakers to minimize any EMC interferences.
For accurate calibration and to minimize cross-contamination, use two
beakers for each buffer solution: one for rinsing the electrode and one for
calibration.
If you are measuring in the acidic range, use pH 7.01 as first buffer
and pH 4.01 as second buffer. If you are measuring in the alkaline
range, use pH 7.01 as first buffer and pH 10.01 or pH 9.18 as
second buffer.
PROCEDURE
Calibration has a choice of five memorized buffers: pH 4.01, 6.86,
7.01, 9.18 and 10.01.
It is recommended to perform a two-point calibration. However, onepoint calibration is also permitted by the instruments.
TWO-POINT CALIBRATION
Submerge the pH electrode and the temperature probe approximately 4 cm (1") into a
buffer solution and stir gently. The temperature
probe should be close to the pH electrode.
Press CAL. The CAL and messages will appear and
7.01 buffer will be displayed on the secondary LCD.

Note: The instruments will automatically skip the buffer used for the
first point. It also skips 6.86 if 7.01 buffer was used and vice
versa. Likewise, it will skip 9.18 if 10.01 buffer was used and
vice versa.
After the first calibration point is confirmed,
immerse the pH electrode and the temperature
probe approximately 4 cm (1) into the
second buffer solution and stir gently. The
temperature probe should be close to the pH
electrode.
If necessary, press the ARROW keys to select a different buffer value.

The symbol will blink on the LCD until the reading is stable.
When the reading is stable, READY message will appear and
CFM message will blink.
Press CFM to confirm calibration. The instrument
will return to measurement mode.
Notes: If the value measured by the meter is not close to the
selected buffer, WRONG and WRONG messages
will blink alternately. In this case check if the correct buffer
has been used, or regenerate the electrode by following the
cleaning procedure (see page 18). If necessary, change the
buffer or the electrode.
The WRONG message and temperature value are displayed blinking if the temperature reading is out of the
defined temperature range of the buffer. Calibration cannot
be confirmed in this situation.

 Press RANGE to display the temperature reading on the LCD during

calibration (HI 2211 only).
ONE-POINT CALIBRATION
Proceed as described in Two-point calibration section.
Press CAL after the first calibration point
was confirmed.
The instrument will return to measurement mode
and will memorize the one-point calibration data.
Note: Press and hold down CFM and then press CAL. The instrument
sets default calibration parameters, displays CLR message for a
few seconds and then returns to normal measurement mode.

TEMPERATURE CALIBRATION
(for technical personnel only)
All the instruments are factory calibrated for temperature.
Hannas temperature probes are interchangeable and no temperature calibration is needed when they are replaced.
If the temperature measurements are inaccurate, temperature
recalibration should be performed.
For an accurate recalibration, contact your dealer or the nearest
Hanna Customer Service Center, or follow the instructions bellow.
Prepare a vessel containing ice and water and another one
containing hot water (at a temperature of around 50 C). Place
insulation material around the vessels to minimize temperature
changes.
Use a calibrated thermometer with a resolution of 0.1 C as a
reference thermometer.
With the instrument off, press and hold down the CAL & MEM
keys, then power on the instrument. The CAL message will
appear and the secondary LCD will show 0.0 C.

ELECTRODE CONDITIONING &

MAINTENANCE

For refillable electrodes:

If the filling solution (electrolyte) is more than 2 cm (1") below the
fill hole, add HI 7082 or HI 8082 3.5M KCl Electrolyte Solution for
double junction or HI 7071 or HI 8071 3.5M KCl+AgCl Electrolyte
Solution for single junction electrodes.
Unscrew the fill hole screw during measurements.
For AmpHel electrodes:
If the electrode does not respond to pH changes, the battery is dead
and the electrode should be replaced.
MEASUREMENT
Rinse the electrode tip with distilled water. Immerse the tip (bottom
4 cm /1) into the sample and stir gently for a few 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 PROCEDURE
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
or HI 80300 Storage Solution or, in its absence, Fill Solution (HI
7071 or HI 8071 for single junction and HI 7082 or HI 8082 for
double junction electrodes). Follow the Preparation Procedure on page
16 before taking measurements.
Note: NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED
WATER.
PERIODIC MAINTENANCE

PREPARATION PROCEDURE
Remove the protective cap of the pH electrode.
DO NOT BE ALARMED IF SALT DEPOSITS ARE PRESENT. This is normal
with electrodes. They will disappear when rinsed with water.
During transport, tiny bubbles of air may form inside the glass bulb
affecting proper functioning of the electrode. These bubbles can be
removed by shaking down the electrode as you would do with a
glass thermometer.
If the bulb and/or junction is dry, soak the electrode in HI 70300 or
HI 80300 Storage Solution for at least one hour.

16

Inspect the electrode and the cable. The cable must be intact and
well connected. No cracks should be seen 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 refillable electrodes:
Refill the reference chamber with fresh electrolyte (HI 7071 or HI 8071
for single junction or HI 7082 or HI 8082 for double junction
electrodes). Allow the electrode to stand upright for 1 hour.
Follow the Storage Procedure above.

TEMPERATURE CORRELATION
FOR p H SENSITIVE GLASS
The resistance of glass electrodes partially depends on the temperature.
The lower the temperature, the higher the resistance. It takes more 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 25 C.

Since the resistance of the pH electrode is in the range of 50-200 Mohms,

the current across the membrane is in the pico Ampere range. Large
currents can disturb the calibration of the electrode for many hours.
For these reasons high humidity environments, short circuits and
static discharges are detrimental to a stable pH reading.
The pH electrodes life also depends on the temperature. If constantly
used at high temperatures, the electrode life is drastically reduced.
Typical Electrode Life
Ambient Temperature
1- 3 years
90 C
Less than 4 months
120 C

Alkaline Error
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 called
alkaline error and causes the pH to be underestimated. Hannas glass
formulations have the indicated characteristics.

RECOMMENDATIONS FOR USERS

Before using these products, make sure they are entirely suitable for
the environment in which they are used.
Operation of these instruments in residential areas could cause
unacceptable interferences to radio and TV equipment, requiring the
operator to follow all necessary steps to correct interferences.
The glass bulb at the end of the pH electrode is sensitive to
electrostatic discharges. Avoid touching this glass bulb at all times.
During operation, ESD wrist straps should be worn to avoid possible
damage to the electrode by electrostatic discharges.
Any variation introduced by the user to the supplied equipment may
degrade the instruments EMC performance.
To avoid electrical shock, do not use these instruments when voltages
at the measurement surface exceed 24 VAC or 60 VDC.
To avoid damage or burns, do not perform any measurement in
microwave ovens.
