GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

HI 2222 is a 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.

Other features include: up to two point calibration with seven memorized

buffers (1.68, 3.00, 6.86, 7.01, 9.18, 10.01 and 12.45 pH), logging

up to 100 samples, GLP, calibration due alarm, pH reading with manual

or automatic temperature compensation and PC software interface.
