The HI5221 is an advanced research grade benchtop pH/mV
meter that is completely customizable with a large color LCD,
capacitive touch keys, and USB port for computer connectivity.
The HI5221 features a universal BNC connection for use
with the expansive line of pH and ORP electrodes that Hanna
Instruments o!ers. The meter is supplied with the HI1131B glass
body, double junction, combination pH electrode that operates
over a wide temperature range from 0 to 100°C. All readings
are automatically compensated for temperature variations with
the separate HI7662-T temperature probe that is included.
The HI5221 can be calibrated up to #ve points with a choice of
eight pre-programmed bu!ers or #ve custom bu!ers. The HI5221
features Hanna’s exclusive CAL Check™ to alert the user of
potential problems during the pH calibration process. Indicators
displayed during calibration include “Electrode Dirty/Broken”
and “Bu!er Contaminated.” The overall probe condition based on
the o!set and slope characteristic of the electrode is displayed
as a percentage after calibration is complete. The calibration
data including date, time, bu!ers used, o!set and slope can be
accessed at any time along with the current measurement by
selecting the Good Laboratory Practice (GLP) display option.
Three selectable logging modes are available: automatic,
manual and AutoHold logging. Up to 100,000 data points
can be recorded in 100 lots with 50,000 records max/lot and
exported to a computer for data review and storage.
