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 or the nearest Hanna Customer Service Center.
Each instrument is supplied complete with:

• 

HI 1131P

 Glass-body Combination pH Electrode with 1 m (3.3 “) cable

• 

HI 7669/2W

 Temperature Probe

• 

HI 76404

 Electrode Holder

• 

pH 4.01 & 7.01

 Buffer Solutions (20 mL each)

• 

HI 7071S

 Electrolyte Solution

• 12 VDC Power Adapter
• Instruction Manual

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

HI 221

 and 

HI 223

  are  logging microprocessor-based pH/ORP/temperature

bench meters with Calibration Check.
Calibration Check performs a set of diagnostic tests during calibration using the

history of electrode slope and offset to detect problems that can cause loss of

accuracy.
Calibration Check Features are:

• Enhanced Calibration Messages

During calibration the user is warned if one or more parameters are not suitable
to perform an accurate calibration.

• Electrode Condition on LCD Display

Determined from the electrode offset and slope.

• Electrode response time on LCD Display

Determined from electrode performance during calibration.

• Calibration Alarm Time Out

Can be programmed from 1 to 7 days or can be disabled.

Other features include:
One or two point calibration with seven memorized buffers (1.68, 4.01, 6.86,

7.01, 9.18, 10.01 and 12.45 pH), logging up to 100 samples (for 

HI 221

)

and 500 samples (for 

HI 223

), last calibration date and data (GLP), pH

reading with manual or automatic temperature compensation and PC software

interface.
