• 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
to rinse thoroughly the electrode with water, and then for some of the next
solution to be measured.

TAKING ORP MEASUREMENTS

pH 209 

can also measure ORP, using an ORP electrode. Hanna Instruments

offers a variety of ORP electrodes for this purpose. Contact your dealer for more
information.

• Connect the ORP electrode to the meter and sub-

merge the tip (4 cm / 1½") into the sample to be
tested.

Note:

ORP measurements are not compensated for temperature variation.

• Press the mV key to enter the mV mode and allow a few minutes for the reading

to stabilize.

• The display will show the ORP (mV) value.

AFTER MEASUREMENTS

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

Power connection

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

Note:

 Make sure the main line is protected by a fuse.

Electrode connection

For 

pH

 or 

ORP

 electrodes with internal reference, connect the electrode to the

BNC socket on the rear panel (#10 on page 4).
For electrodes with separate reference, plug the BNC connector of the electrode
to the BNC socket (#10 on page 4), and the reference electrode to the proper
socket (#11 on page 4) on the rear panel.

Note:

 To prevent damage to the electrode, remove the pH electrode from the

solution before turning the meter off. With the meter OFF, detach the
electrode and immerse it 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

button.

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

sample and shake briefly.

• Take the temperature of the solution with the sup-

plied 

HI 98501

 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.
