PRELIMINARY EXAMINATION

material and examine it carefully to make

returned in the original packing materials
together with the supplied accessories.
Hanna Instruments microprocessor-based So-
dium (HI931101) / Sodium Chloride
(HI 931100/HI 931102) analysers, are housed
in rugged, lightweight material designed for
single-handed use.
To assure trouble-free operations, the meters'
circuitry has a built-in protection against elec-
tromagnetic interference.
All meters come equipped with a large and
easy-to-read LCD, which shows sodium/so-
dium chloride and temperature values simul-
taneously and guides the user through the
calibration procedure with easy-to-follow
graphic symbols.
In addition, HI 931101 and HI 931102 provide
pNa or % NaCl readings respectively through
the MODE key.
Automatic calibration, rundown batteries indi-
cator and water-resistant housing are the fea-
tures which make these meters easy to use
and versatile both in the laboratory and in
the field applications.
