PRELIMINARY EXAMINATION

HI5221 and HI5222 are professional bench meters with a color graphic LCD for pH (with Calibration

Check), ORP (Oxidation Reduction Potential), ISE (HI5222 only) and Temperature measurements.

The display can be configured as a single channel or dual channel display (HI5222 only). Each channel

can be configured as pH, mV, Relative mV or ISE (HI5222 only).

The main features of the instruments are:

• Single (HI5221) or two (HI5222) input channels;

• Capacitive touch keypad;

• pH calibration using up to five pH buffers: choose from the list of Hanna Instruments buffers

(pH 1.68, 3.00, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) or custom buffers (up to 5 custom

buffers);

• ISE calibration using up to five standards: choose from the list of nominal standard values

(e.g. for ppm: 0.010, 0.100, 1.00, 10.0, 100, 1000, 10000 ppm) and/or from 5 user-supplied

custom standard values (up to 5 custom solutions);

• AutoHold feature to freeze first stable reading on the LCD;

• Two selectable alarm limits;

• User Selectable logging modes: Automatic logging, Manual logging with or without AutoHold;

• Continuous Lot logging directly on meter, with selectable log interval: Store up to 100,000 total

data points;

• Up to 100 logging lots; a single lot can have up to 50,000 data points; HI5222 (same for each

measurement channel). Log files include GLP information;

• Basic Measurement can be viewed with detailed GLP information, or with a Graph or a Log History;

• User-friendly interface on large color graphic LCD (240 x 320 pixels) with user selectable color

palette;

• PC interface via USB; download logged data to PC or use for Real time logging (HI92000

PC application required);

• Dedicated Help key with contextual message;

• Profile feature: store up to ten different user setup (HI5222 - five on each channel).

POWER CONNECTION

Plug the 12 Vdc adapter into the power supply socket.

Notes: These instruments use non-volatile memory to retain the pH, ISE calibrations and all

other settings, even when unplugged.

Make sure a fuse protects the main line.

ELECTRODE AND PROBE CONNECTIONS

For pH or ORP measurements, connect a pH/ORP electrode with internal reference to the BNC

connector located on the rear panel of the instrument (to the desired channel - HI5222 only).

For ISE measurements, (HI5222 only) connect, to the desired channel, an ISE electrode with internal

reference to the BNC connector located on the rear panel of the instrument.

For electrodes with a separate reference, connect the electrode’s BNC to the BNC connector and the

electrode’s reference to the reference input socket.

For temperature measurement and automatic temperature compensation, connect the temperature

probe to the appropriate socket (to desired channel - HI5222 only).

INSTRUMENT START UP

• Please ensure that the capacitive keypad is not covered by hand or other objects at the meter

power on.

• Turn the instrument on from the power button located on the rear panel of the instrument.

• Please wait until the instrument finishes the initialization process.

Note: It is normal for the loading process to take a few seconds. If the instrument doesn’t

display the next screen, restart the meter using the power button. If the problem persists,

contact your local Hanna Instruments Office.
