Hanna publishes a wide range of catalogs and

handbooks for an equally wide range of applications.

The reference literature currently covers areas such

as:

• Water Treatment

• Process

• Swimming Pools

• Agriculture

• Food

• Laboratory

• Thermometry

and many others. New reference material is constantly

being added to the library.

For these and other catalogs, handbooks and leaflets,

Recommendations for Users

Before using this product, make sure that it is entirely suitable for the environment in which it is

used.

Operation of this instrument in residential areas could cause unacceptable interferences to radio and

TV equipment, requiring the operator to take 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 this instrument when voltages at the measurement surface

exceed 24VAC or 60VDC.

To avoid damages or burns, do not perform any measurement in microwave ovens.

PRELIMINARY EXAMINATIONPRELIMINARY EXAMINATION

PRELIMINARY EXAMINATION

The Hanna pH 210, pH 211, pH 212 and pH 213 are micropro-

cessor-based bench meters for pH and temperature measurements.

pH 211 and pH 213 can also measure ion concentration (ISE) and

ORP (Oxidation Reduction Potential) in the mV range.

The pH measurements are compensated for temperature effect manu-

ally or automatically with the HI 7669/2W temperature probe.

The meter comes 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 make the calibration procedure error-

free.

Through the RS 232C serial port you can transfer the data to a PC

(pH 212 and pH 213 only).

OPERATIONAL GUIDEOPERATIONAL GUIDE

OPERATIONAL GUIDE

Power connection

Plug the 12VDC adapter into the power supply socket (#10 on page

4; #11 on page 6).

Note: pH 212 and pH 213 use an EEPROM to retain the pH, mV

and temperature calibrations as well as the serial communica-

tion setting. The instrument will retain the data after a

calibration or serial communication setting, even when it is

unplugged.

Note:Note:

Note: Make sure the main line is protected by a fuse.

Electrode and Probe connections

For combination pH or ORP electrodes (with internal reference)

connect the electrode's BNC to the socket on the back of the meter

(#11 on page 4; #12 on page 6).

For electrodes with a separate reference, connect the single cell

electrode's BNC to the BNC socket (#11 on page 4; #12 on page 6)

and the reference electrode plug to the reference socket (#12 on

page 4; #13 on page 6).

For temperature measurements and automatic temperature compen-

sation connect the temperature probe to the appropriate socket

(#13 on page 4; #14 on page 6).

Note: to prevent damage to the electrode, remove the pH electrode

from the solution before turning the meter off.

If the meter is OFF, detach the electrode from the meter before

immersing the electrode in the storage solution.

pH MEASUREMENTS

Make sure that the instrument has been calibrated before taking pH

measurements.

• Switch the instrument on by pressing the ON/OFF

switch.The meter automatically defaults to the pH mea-

surement mode.

• Submerge the tip (4cm/1½") of the elec-

trode and the temperature probe into the

sample to be tested. Allow time for the

electrode to stabilize.

• pH is displayed on the primary display and temperature on the

secondary one.

• With pH 211 and pH 213 it is also possible to view the mV

reading by pressing the "RANGE" key.

If measurements are taken successively in different samples, it is

recommended to rinse the electrode thoroughly with deionized water

or, if not available, tap water first and then with some of the next

sample to condition the electrode before immersing it in the sample.

The pH reading is affected by temperature. In order for the meter to

measure the pH accurately, temperature must be taken into consid-

eration. To use the Automatic Temperature Compensation feature,

connect and submerge the HI 7669/2W temperature probe into the

sample as close to the electrode as possible and wait for a couple of

minutes.

If the temperature of the sample is known or tests are always

performed at the same temperature you can simply manually

compensate for it. For this purpose the temperature

probe must be disconnected.

The display will then show the default temperature

of 25C or the last recorded temperature reading

with the "C" symbol blinking.

Note the temperature of the sample using a

ChecktempC or an accurate reference thermometer.

The temperature can now be adjusted with the VC and WC keys.

ORP MEASUREMENTS (pH211 and pH213 only)

An optional ORP electrode must be used to perform ORP measurements

(see accessories).

Oxidation-reduction potential (REDOX) measurements provide the quan-

tification of the oxidizing or reducing power of the sample tested.

To correctly perform a redox measurement, the surface of the ORP

electrode must be clean and smooth.

• Switch the meter on and press the "RANGE" key to

enter the mV mode.

• Submerge the ORP electrode tip (4cm/1½") into

the sample. Allow a few minutes for the reading

to stabilize.

• The meter displays the mV reading on the primary display.

• If readings are out of range, "---" will appear on the LCD.

TAKING TEMPERATURE MEASUREMENTS

Taking a temperature measurement is very easy.

Connect the HI 7669/2W temperature probe and

turn the instrument on. Dip the temperature probe

in the sample and allow the reading on the second-

ary display to stabilize.

HOLD FUNCTION

Press and hold MEM. The last reading will be frozen on the display

until MEM is released. During this operation, the MEM indicator is also

shown on the LCD.

Press MR and the previously memorized reading will be

displayed with the MEM indicator on the LCD.
