PRELIMINARY EXAMINATION
Remove the instrument from the packing
material and examine it carefully to make
sure that no damage has occurred during
shipping. If there is any noticeable damage,
notify your Dealer.
Each meter is supplied complete with 4 x 1.5V
AA size batteries and rugged carrying case.
Note: Save all packing materials until you
are sure that the instrument functions
correctly. All defective items must be
returned in the original packing materials
together with the supplied accessories.
GENERAL DESCRIPTION
Hanna Instruments microprocessor-based Sodium (HI 931101) / 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 electromagnetic interference.
All meters come equipped with a large and
easy-to-read LCD, which shows sodium/sodium chloride and temperature values simultaneously 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 indicator and water-resistant housing are the features which make these meters easy to use
and versatile both in the laboratory and in
the field applications.

For greatest accuracy, calibration should be
performed (or at least verified) every day for
measurements taken in the same type of
samples (e.g. cheese) or every time the
sample type is changed (e.g. cheese, meat,
sea water, etc.).
The best working temperature is around 2025°C (68-77°F). For greater accuracy, perform the calibration of the meter with standard solution at a temperature as close as
possible to the temperature of the sample
(± 1°C/±2°F).

Remove the protective cap
of the FC 300B sodium-sensitive electrode and, if possible, rinse it with some of
the sample you are going to
measure.
Lower the rubber sleeve to
get the junction to work properly.
Immerse the tip of the
FC300B electrode (2.5 cm/
1" i.e. the electrode junction must be completely immersed) into the sample to
be tested without touching
the bottom of the beaker.

Wait for up to 10 to 15 minutes to allow for
the electrode to adjust and stabilize, i.e.
until there is no drifting for at least a couple
of minutes.
During measurement, if possible, the sample
should be gently stirred (100 rpm).
pNa (for HI931101) and NaCl% (for HI931102)

Press the MODE key during measurement to
convert the displayed value of HI 931101 to
pNa.
pNa = -log a
