• Press the pH key to display the pH measurement.

• The display shows the pH value of the test solution compensated
for temperature.

If measurements are taken in different samples successively, it is
recommended that the electrode be rinsed thoroughly for better condi­tioning and to eliminate cross-contamination of the sample.

For the rinsing process, it is recommended to use a liberal amount of
the next solution to be measured.

TAKING ORP MEASUREMENTS

pH 209 has the capability to take ORP measurements, using an ORP
electrode. Hanna Instruments offers a variety of ORP electrodes for this
purpose (see accessories). Contact your Dealer for more information.

• Connect the ORP electrode to the meter and
submerge the tip (4 cm / 1½") into the sample
to be tested.

Note: ORP measurements are taken without temperature compensa-

tion.

• Press the mV key to enter the mV mode. Allow a few
minutes for the reading to stabilize.

• The display will indicate the mV value (positive or negative).

AFTER MEASUREMENTS

• Press the ON/OFF switch again to switch the instrument off.

Power connection

Plug the supplied 12 Vdc adapter into the power supply socket (#9
on page 4).

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

Electrode connection

For combination pH or ORP electrodes (with internal reference)
connect the electrode's BNC to the socket provided (#10 on page 4).

For an electrode with a separate reference, connect the measuring
electrode's BNC to the BNC socket (#10 on page 4) and the reference
electrode's jack to the socket provided (#11 on page 4).

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.

TAKING pH MEASUREMENTS

Make sure that the instrument has been calibrated for pH before
taking pH measurements.

• Switch the instrument on by pressing the ON/OFF
switch.

• Immerse the electrode tip (4 cm/1½") into the
sample and shake briefly.

• Take the temperature of the solution with a
ChecktempC or a glass thermometer (e.g.25°C).

• Press the °C key to display temperature setting on the LCD and
adjust the temperature knob to display the temperature of the
sample.

IMPORTANT

The instrument's pH range should be re-calibrated:

• When the meter is new.

• Whenever the pH electrode is replaced.

• At least once a month.

• After use in aggressive chemicals.

• After cleaning procedure and changing the reference electrolyte.

• For greatest accuracy.

INITIAL PREPARATION

Pour small quantities (up to 4cm / 1½" level)
of pH 7.01 (HI 7007) and pH4.01 (HI 7004)
or pH 10.01 (HI 7010) solution into clean
beakers. If possible use plastic beakers to
minimize any EMC interferences.

If you are measuring in the acid range, use pH 4.01 as second
buffer; if you are measuring in the alkaline range, use pH 10.01 as
second buffer.

For accurate calibration, use two bea­kers for each buffer solution; the first
for rinsing the electrode, the second
for calibration. In this way, contami­nation of the buffer is minimized.

Note: The electrode should be submerged approximately 4 cm (1½")

into the solution.

Note: If you need to calibrate to NBS standards, use pH 6.86 (HI

7006) and pH 9.18 (HI 7009) instead of pH 7.01 and 10.01

respectively.

Use a ChecktempC or a glass thermometer as reference.

PROCEDURE

• Switch the instrument on by pressing the
ON/OFF button.

• Rinse and immerse the pH electrode into
pH 7.01 buffer and shake briefly. Wait for
the reading to stabilize.

pH CALIBRATION

• Note the temperature of the buffer solution using
a ChecktempC or a glass thermometer
(e.g.20°C).

• Press the °C key to select temperature setting.

• Adjust the Temperature knob until the LCD shows the noted
temperature.

• Press the pH key to select pH measurement.

• Wait a couple of minutes and adjust the OFFSET knob until
display shows the pH value at the noted temperature (see the pH
versus temperature chart).

• Rinse and immerse the pH electrode in pH 4.01/pH 10.01 buffer
and shake briefly.

• Wait a couple of minutes and adjust the SLOPE knob until
display shows the pH value at the noted temperature (see the pH
versus temperature chart).

• The pH calibration is now complete.

ELECTRODE CONDITIONING

AND MAINTENANCE

PREPARATION

Remove the protective cap.
DO NOT BE ALARMED IF SALT DEPOSITS ARE PRESENT. This is normal
with electrodes and 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
storage solution for at least one hour.

pH VALUES AT VARIOUS TEMPERATURES

Temperature has an effect on pH. The calibration buffer solutions are
affected by temperature changes to a lesser degree than normal
solutions.

For manual temperature calibration please refer to the following chart.

For instance, if the buffer temperature is 25°C, the display should
show pH 4.01, 7.01 or 10.01 at pH 4, 7 or 10 buffers, respectively.

At 20°C, the display should show pH 4.00, 7.03 or 10.06. The meter
reading at 50°C will then be 4.06, 6.98 or 9.82.

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.

Follow the Storage Procedure above.

CLEANING PROCEDURE

General Soak in HI 7061 general cleaning solution for approxi-

mately 30 minutes.

Removal of films, dirt or deposits on the membrane/junction:

- Protein Soak in HI 7073 protein cleaning solution for 15 min.

- Inorganic Soak in HI 7074 inorganic cleaning solution for 15
minutes.

- Oil/grease Rinse with HI 7077 Oil & Fat cleaning solution.

IMPORTANT: After performing any of the cleaning procedures rinse
the electrode thoroughly with distilled water, 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 electrolyte level (in refillable

electrodes only): refill with fresh HI 7071 for single junction or
HI 7082 for double junction electrodes.

• Dry Membrane/Junction: soak in HI 70300 storage solution for

at least 1 hour.

• Drifting: soak the electrode tip in warm (approx. 50-60°C)

Hanna HI 7082 solution for one hour and rinse the tip with
distilled water. Refill with fresh HI 7071 for single junction
electrodes and HI 7082 for double junction electrodes (refillable
electrodes only).

• Low Slope: refer to the cleaning procedure above.

• No Slope: check the electrode for cracks in glass stem or bulb

and replace the electrode.

• Slow Response/Excessive Drift: soak the tip in HI 7061

solution for 30 minutes, rinse thoroughly in distilled water and
then follow the Cleaning Procedure above.

For refillable electrodes:

If the filling solution (electrolyte) is more than 2½ cm (1") below the
fill hole, add HI 7082 3.5M KCl electrolyte solution for double junction
or HI 7071 3.5M KCl+AgCl electrolyte solution for single junction
electrodes.

For a faster response, unscrew the fill hole screw during measure­ments.

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 (bottom 4
cm /1½") in 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

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 protective cap with a few drops of HI 70300 storage
solution or, in its absence, electrolyte solution (HI 7071 for single
junction, or HI 7082 for double junction electrodes). Follow the
Preparation Procedure above before taking measurements.

NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED WATER.

PERIODIC MAINTENANCE

Inspect electrode and cable. The cable used for 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.

For refillable electrodes:

Refill the reference chamber with fresh electrolyte (HI 7071 for single
junction or HI 7082 for double junction electrodes). Allow the electrode
to stand upright for 1 hour.

TEMPERATURE-RESISTANCE 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.

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

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 to be underestimated. Hanna's glass
formulations have the indicated characteristics.
