PRELIMINARY EXAMINATION

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.

Each meter is supplied complete with:

•HI 1332B plastic-body combination double-junction refillable pH electrode with BNC connector and 1m (3.3') cable;

•Instruction Manual;

•12VDC adapter (HI710005 or HI710006);

•Dust cover.

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.

GENERAL DESCRIPTION

pH 209 bench-top pH meter is designed for simplicity of use.

It features a large easy-to-read liquid crystal display (LCD) and user friendly keyboard.

The pH calibration is made simple through the easy-to-operate front panel knobs for offset and slope adjustment.

A front knob is provided for easy manual temperature compensation of the pH reading.

pH 209 can also measure ion concentration (ISE) and ORP (Oxidation Reduction Potential) in the mV range.

The range selection (pH, mV or C for temperature compensation) is made simple through the front membrane keyboard.

The large LCD is provided with arrows that quickly and clearly indicate the selected range.

It is also available the model pH209R with recorder output feature.

OPERATIONAL GUIDE

Power connection

Plug the 12VDC adapter (HI710005 or HI710006) into the power supply socket (#9 on page 4).

Note: make sure the main 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.
	(1½") 4cm

•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.

6

• 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	(1½") 4cm
to be tested.

Note: ORP measurements are taken without temperature compensation.

•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.
