pH 210, pH 211, pH 212 and pH 213 are guaranteed for two years against
defects in workmanship and materials when used for their intended purpose and
maintained according to instructions. Electrodes and probes are guaranteed for
six months. This warranty is limited to repair or replacement free of charge.
Damage due to accidents, misuse, tampering or lack of prescribed maintenance
is not covered.
If service is required, contact the dealer from whom you purchased the instrument.
If under warranty, report the model number, date of purchase, serial number and
the nature of the problem. If the repair is not covered by the warranty, you will be
notified of the charges incurred. If the instrument is to be returned to Hanna Instruments, first obtain a Returned Goods Authorization number from the Technical
Service department and then send it with shipping costs prepaid. When shipping
any instrument, make sure it is properly packed for complete protection.
The Hanna pH 210, pH 211, pH 212 and pH 213 are microprocessor-
based pH and Temperature bench meters.
pH 211 and pH 213 can also measure 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 7669/2W 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.
Through the RS232 serial port data can be transferred to a PC
(pH 212 and pH 213 only).
Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipping.
If there is any damage, notify your Dealer or the nearest Hanna
Customer Service Center.
Each instrument is supplied with:
• HI 1131B Glass-body Combination pH Electrode
• HI 7669/2W Temperature Probe
• HI 76404 Electrode Holder
• pH 4.01 & 7.01 Buffer Solutions, 20 mL each
• HI 7071S Electrolyte Solution
• 12VDC Power Adapter
• Instruction Manual
Note: Save all packing material until you are sure that the
instrument functions correctly. All defective items must be
returned in the original packing with the supplied accessories.

Plug the 12 VDC adapter into the power supply socket.
Notes: • These instruments use non volatile memory to retain the
pH, mV, temperature calibrations and all other settings,
even when unplugged.
• Make sure a fuse protects the main line.
ELECTRODE AND PROBE CONNECTIONSELECTRODE AND PROBE CONNECTIONS
ELECTRODE AND PROBE CONNECTIONSELECTRODE AND PROBE CONNECTIONS
ELECTRODE AND PROBE CONNECTIONS
For pH or ORP measurements connect an electrode with internal
reference to the BNC connector on the back of the instrument.
For electrodes with a separate reference connect the electrode’s BNC to the
BNC connector and the reference electrode plug to the reference socket.
For temperature measurements and automatic temperature compensation connect the temperature probe to the appropriate socket.

• Turn the instrument on by pressing the ON/OFF
switch.
• All LCD tags are displayed and a beep is heard
while the instruments perform a self test (pH 212
and pH 213 only).

Make sure the instrument has been calibrated before
taking pH measurements.
• Submerge the electrode tip and the temperature
probe approximately 4 cm (1½”) 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.
• If the pH reading is out of range, “----” will be displayed on the
LCD.
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 7669/2W 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,simple 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).

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/
1½") into the sample to be tested and allow a
few seconds for the reading to stabilize.

CFM to confirm or CAL to escape without saving.

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
PREPARATIONPREPARATION
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.

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, one-
point calibration is also provided 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 “

buffer will be displayed on the secondary LCD.
• If necessary, press the ARROW keys to select a different buffer value.
• The “ ” tag will blink on the LCD until the reading is stable.
