PRELIMINARY EXAMINATION
GENERAL DESCRIPTION
HI 8314
is an hand-held pH/mV/°C meter designed for to be
rugged, easy-to-use, reliable and practical.
It is ideal for education and for measurements on the field.
The pH, mV and °C ranges are easily selected using the
membrane keyboard on the front panel.
Calibration procedure is very simple and adjustments are
easily made with two trimmers on the front panel.
The built-in temperature sensor in the pH electrode allows
automatic temperature compensation of pH readings.
Moreover,
HI 8314
features a low battery indicator that
alerts the user when the bettery needs to be replaced.

Recommendations for Users
Before using these products, make sure that they are entirely suitable for the environment in
which they are used. Operation of these instruments in residential area could cause unaccept-
able interferences to radio and TV equipments, requiring the operator to take all necessary
steps to correct interferences. Any variation introduced by the user to the supplied equipment
may degrade the instruments' EMC performance. To avoid damages or burns, do not perform
any measurement in microwave ovens.
