PRELIMINARY EXAMINATION
GENERAL DESCRIPTION
HI 9214 is a compact, stick-type, microprocessor-based pH/°C
meter designed to be easily carried anywhere.
Main features are: interchangeable plastic-body electrode,
simple controls on the front panel, low battery detector, simple
calibration procedure and lightweight ABS plastic housing.
The HI 12170 pH-electrode has a built-in temperature sensor
for quick and accurate temperature measurements, and auto-
matic temperature compensation.
The meter has three memorized buffer values (pH 4.01, pH
7.01, pH 10.01) and automatic buffer recognition to avoid
errors during calibration. There are no trimmers making
calibration an easy process, even for non-technical personnel.
The electrode screws directly onto the meter’s housing without
requiring cables or separate temperature probes.
The electrode Ultem
®
body is rugged and will stand up to
the effects of most chemicals in the lab and industry.
