GENERAL DESCRIPTION
HI 222 is a logging microprocessor-based pH/ORP/temperature bench meter
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 listed below:
• 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 1 or 2-point pH 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, last calibration date and data (GLP), pH reading with manual
or automatic temperature compensation and PC interface software.
The pH 3.00 memorized buffer makes the instrument useful for wine pH
measurements.
