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.
HI2221
and
HI2223
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.
Other features include: up to five pH point calibration with seven mem‑
orized buffers (1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45 pH),
logging up to 100 samples (for
HI2221
) and 500 samples (for
HI2223
),
GLP, calibration due alarm, pH reading with manual or automatic
temperature compensation and PC software interface.
