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.
Hanna Instruments microprocessor-based So-
dium (HI 931101) / Sodium Chloride
(HI931100/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.

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 20-
25°C (68-77°F). For greater accuracy, per-
form the calibration of the meter with stan-
dard solution at a temperature as close as
possible to the temperature of the sample
(± 1°C/±2°F).

TAKING SODIUM MEASUREMENTS
Remove the protective cap
of the FC300B sodium-sen-
sitive electrode and, if pos-
sible, rinse it with some of
the sample you are going to
measure.
Lower the rubber sleeve to
get the junction to work prop-
erly.
Immerse the tip of the
FC300B electrode (2.5 cm/
1" i.e. the electrode junc-
tion must be completely im-
mersed) 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)
measurements
Press the MODE key during measurement to
convert the displayed value of HI 931101 to
pNa.
pNa = -log aNa
where aNa is the activity of ion Na.
Press the MODE key during measurement to
convert the displayed value of HI 931102 to
%.

TAKING TEMPERATURE MEASURE-
MENTS
To take temperature measure-
ments, connect the tempera-
ture probe, turn the instrument
on and dip the liquid/general
purpose temperature probe
HI 7662 into the sample. Al-
low the reading to stabilize.
Note: the temperature is al-
ways displayed on the
secondary display.
AFTER USE
Turn the meter off by press-
ing the ON/OFF key again.
For a faster and accurate mea-
sure, the electrode should be
stored in a solution with a Na/
NaCl concentration similar to
the sample to be measured.
Upper the rubber sleeve after
use.
For infrequent use (once a
month or less) store the elec-
trode dry. Before using it
again, let it condition over-
night in HI7081/HI8081 (30.0
g/L NaCl) or HI7086/HI8086
(23 g/L Na 1M)
To avoid very long re-
sponse time, do not store
or rinse the electrode with
deionized water. Never rub
or blot the electrode.

Na CALIBRATION (HI 931101)
The calibration is performed by immersing
the FC 300B sodium-sensitive electrode in 2
different standard Na solutions to achieve ac-
curate 2 point calibration.
It is also possible to calibrate just the offset
(2.3 g/L Na) following the single point calibra-
tion procedure described below.
For best accuracy, a two-point calibration is
recommended (see below).
PREPARATION
• Pour small quantities of
HI7080 or HI8080 (2.3
g/L Na) solution and
HI7087 or HI8087 (0.23
g/L Na) or HI7086 or
HI8086 (23 g/L Na) into
two clean beakers.
To obtain accurate readings, use HI7080/
HI8080 and HI7087/HI8087 if you are go-
ing to measure samples with low sodium
content (below 2.3 g/L) or HI7080/HI8080
and HI7086/HI8086 if you are going to
measure samples with high sodium con-
tent (over 2.3 g/L).
• For accurate calibra-
tion use two bea-
kers for each buffer
calibration, the first
one for rinsing the electrode, the second
one for calibration. This way, contamina-
tion of the buffer is minimized. Whenever
possible use plastic beakers to minimize
any EMC interferences.
• Turn the meter on by
pressing the ON/OFF key.

• Remove the protective cap of the

• Lower the rubber sleeve to get the

SINGLE POINT CALIBRATION (OFFSET)
• Dip the FC 300B sodium

Note: the electrode

mersed approxi-
mately 2.5 cm (1")

• Press the CAL key. The "CAL" and "BUF"
indicators will be displayed with the "BUF"

• As soon as the standard
solution is recognized,
the BUF symbol stays
still while the " "

blink indicating that the
electrode is stabilizing.
The value of the stan-

will be displayed on the

• If the CAL key is pressed

TWO POINT CALIBRATION
• Proceed as described in "Single Point Cali-
bration" but do not quit calibration by press-
ing the CAL key.
• After the first point is con-
firmed, immerse the
FC 300B electrode into the
second buffer solution at
0.23 g/L Na (HI7087/
HI 8087)or 23 g/L Na
(HI 7086/HI8086).
Note: the electrode should
be immersed ap-
proximately 2.5 cm
(1") into the solu-
tion.
• Select the buffer value by
pressing the BUF key.
Make sure that the buffer
value selected through the
BUF key corresponds to
the one being used for the
second point calibration.

will stay still on the dis-

the meter is stabilizing its

• Once stabilized "CON"

Wait for a couple of min-
utes and press the CFM

NaCl CALIBRATION (HI931100/HI931102)
The calibration is performed by immersing
the FC 300B sodium-sensitive electrode in 2
different standard NaCl solutions to achieve
accurate 2 point calibration.
It is also possible to calibrate just the offset
(3.00 g/L NaCl) following the single point cali-
bration procedure described below.
For best accuracy, a two-point calibration is
recommended (see below).
PREPARATION
• For HI931100 and HI931102:
Pour small quantities of
HI 7083 or HI 8083 (3.00 g/L
NaCl) solution and HI 7085
or HI 8085 (0.30 g/L) or
HI 7081 or HI 8081 (30 g/L)
into two clean beakers.
To get accurate readings use HI 7083/HI 8083
and HI 7085/HI8085 if you are going to mea-
sure samples with low sodium chloride con-
tent (below 3 g/L) or HI 7083/HI8083 and
HI 7081/HI8081 if you are going to measure
samples with high sodium chloride content
(over 3 g/L).
• For accurate calibra-
tion, use two bea-
kers for each buffer
calibration, the first
one for rinsing the electrode, the second
one for calibration. This way, contamina-
tion of the buffer is mini-
mized. Whenever possible

mize any EMC interferences.
