GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

The Hanna HI 2210 and HI 2211 are microprocessor-based pH and
temperature bench meters.

HI 2211 can also be used for ion concentration (ISE) and Oxidation
Reduction Potential (ORP) in the mV range.

pH measurements are compensated for temperature effect manually or
automatically with the HI 7662 temperature probe.

The instrument is equipped with a large easy-to-read LCD which shows
the pH (or mV) and temperature simultaneously, together with graphic
symbols.

The calibration process is guided step by step through clear indications on
the LCD. A stability indicator makes the calibration procedure error-free.

Hanna Instruments reserves the right to modify the design,

construction and appearance of its products without advance notice.

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

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.

PREPARATIONPREPARATION

PREPARATION

PREPARATIONPREPARATION

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.

PROCEDUREPROCEDURE

PROCEDURE

PROCEDUREPROCEDURE

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.

• Submerge the pH electrode and the tempera­ture probe approximately 4 cm (1½") into a
buffer solution and stir gently. The temperature
probe should be close to the pH electrode.

• Press CAL. The “CAL” and “

“7.01” buffer will be displayed on the secondary LCD.

• 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 and close to the selected buffer,
“READY” message will appear and “CFM” message will blink.

• Press CFM to confirm calibration.

• The calibrated value is then displayed on the
primary LCD and the secondary LCD will display
the second expected buffer value.

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 (1½”) 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.

All the instruments are factory calibrated for temperature.
Hanna’s temperature probes are interchangeable and no tempera-

ture 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 ºC). Place
insulation material around the vessels to minimize temperature
changes.

• Use a calibrated thermometer with a resolution of 0.1 ºC 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 ºC.

• Immerse the temperature probe in the vessel with ice and water
as near as possible to the reference thermometer. Allow a few
seconds for the probe to stabilize.

• Use the ARROW keys to set the reading on the secondary LCD to
that of ice and water, measured by the reference thermometer.

• When the reading is stable and close to the selected calibration
point, “READY” message will appear and “CFM” message will blink.

• To confirm press CFM. The secondary LCD will show 50.0 ºC.

• Immerse the temperature probe in the second vessel as near as

point, “READY” tag will appear and “CFM” tag will blink.

• Press CFM to confirm. The instrument returns

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 electrode’s 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 Less than 1 month

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. Hanna’s 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 instrument’s 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.
