GENERAL DESCRIPTION

HANNA instruments® has designed these two rugged
waterproof salinity and sodium meters for regular use
in the lab, as well as in harsh processing
environments.
HI 931100 is an ion-selective meter that uses a sodium
electrode to read the salt (NaCl) content of a solution.
HI 931100 autoranges (4 scales available) from sample
to sample allowing an extremely wide range of
measurements without recalibration.
HI 931101 employs the FC 300B combination
sodium electrode to provide sodium readings from 15.0
mg/L to 60 g/L.
The calibration is automatic at 2 points, the first is at

2.3 g/L while the second can be either at 0.23 g/L (low
range) or at 23.0 g/L (high range).
A separate temperature probe, HI 7662, provides tem­perature readings from 0 to 80ºC.

INITIAL PREPARATION

Each meter is supplied com­plete with four 1.5V AA batter­ies.

Remove the back cover, unwrap
the batteries and install them
while paying attention to their
polarity.

PROBE CONNECTION

Connect the FC300B sodium
electrode to the BNC socket on
the top of the instrument.

Connect the HI 7662 tempera­ture probe to the RCA socket.

SODIUM

ELECTRODE

TEMPERATUR
PROBE

For accurate readings, calibration should be per­formed (or verified) every day if measuring the same
type of samples (e.g. cheese), or every time the
sample type is changed (e.g. cheese, meat, sea
water, etc.).

The recommended working temperature is around
20-25°C (68-77°F). For greater accuracy, perform
the calibration with standard solutions at a tempera­ture as close as possible to the temperature of the
sample.

TAKING SODIUM MEASUREMENTS

Remove the protective cap from the
FC300B sodium electrode and, if
possible, rinse it with some of the
sample to be measured.

The temperature probe can be
used independently to take tem­perature measurements.

If the probe is not plugged in,
the secondary display shows

NaCl

gm

"25°C" with the "°C" indicator
blinking.

To switch the instrument on,
press and hold the ON/OFF key
for a fraction of a second.

These meters have a built-in protection against elec­tromagnetic interferences and the holding of the
keys is to ensure that the commands are not mis­taken for erroneous signals.

In order to take accurate measurements, make
sure the instrument is calibrated before use
(see "Calibration" sections for details).

Shift downwards the rubber sleeve
(see picture) to have a properly work­ing junction.

°C

Immerse the tip of the FC300B elec­trode (at least 2.5 cm/1") into the
sample to be tested while making
sure that the electrode junction is
completely immersed, and without
touching the bottom of the beaker.

Wait for approximately 10 to 15 minutes to allow
for the electrode to adjust and stabilize, i.e. until
no drifting is observed for at least a couple of
minutes.

During measurement, if possible,
the sample should be gently
stirred (100 rpm).

less), store it dry. Before using it again, let it
condition overnight in HI 7081 (30.0 g/L NaCl) or HI

7086 (23 g/L Na 1M)
To avoid very long response time, do not store

or rinse the electrode with deionized water. Do
not rub the electrode.

Note: The temperature is always

displayed on the secondary

SPEED

2. Pour a quantity (X g) in a glass beaker. Add
(X) x 10 mL of deionized water (note: ignoring
water content of cheese and meat).

3. Cover the beaker to prevent any spilling during
stirring, place the beaker on a hot plate stirrer
and agitate the sample at 40-50°C (104-122°F)
for 15-20 minutes.

4. Let the sample cool to the ambient temperature,
then filter it.

5. Dip the FC 300B sodium electrode into the fil-
tered sample. The tip of the electrode should be
immersed for approximately 2.5 cm/1" (i.e. the
electrode junction must be completely immersed)
without touching the bottom of the beaker. Dur­ing measurement, the sample should be gently
stirred (100 rpm).

6. Wait for the reading to stabilize, i.e. no drift
should be observed for at least a couple of
minutes. Note the measured value.

7. Since the dilution rate is 1/10, the reading in the
g/L range has to be divided by 100 to get the
actual reading of NaCl (per gram of cheese or
meat), or the value can be considered directly
expressed in % of NaCl.

Note: A response time of 10 to 15 minutes for the

first measurement of cheese or meat, is the
correct expected time for the electrode to
stabilize. Next measurements of cheese or
meat samples will require shorter response
time (less than 2 minutes). Do not rinse the
sodium electrode between subsequent mea­surements since contamination is negligible.

IONIC STRENGTH ADJUSTER (ISA)

When the NaCl concentration of the sample is lower
than 5 g/L, it is recommend to use the HI 7090 ISA
solution. In such case, calibration should be per­formed with standard solution containing 2% of ISA.

ISA (Ionic Strength Adjuster) = 50% of NH4Cl 4M +
50% of NH4OH 4M (use 2 mL of ISA every 100 mL
of sample).

1918

TEMPERATURE

The best working temperature is around 20-25°C
(68-77°F).

TEMPERATURE CALIBRATION

(for Technical Personnel only)

For greatest accuracy, it is recommended to cali­brate the meter with standard solution at a tempera­ture as close as possible to the temperature of the
sample (±1°C/±2°F).

Na CONCENTRATION WITH HI 931100

It is always possible to determine the Na concentra­tion by using the formula:

XNa = X

• (23 / 58.4)

NaCl

where

XNa = concentration of Na

and

X

= concentration of NaCl

FC300B CONDITIONING & MAINTENANCE

PREPARATION

Remove the protective cap.
DO NOT BE ALARMED IF ANY

SALT DEPOSITS ARE PRESENT.
This is normal with sodium electrodes
and they will disappear when rinsed
with water.

During transport tiny bubbles of air
may have formed inside the glass
bulb. The electrode cannot function
properly under these conditions.
These bubbles can be removed by
"shaking down" the electrode as you
would do with a glass thermometer.

If the bulb and/or junction
are dry, soak the elec­trode in HI 7081 (NaCl

30.0 g/L) solution over­night before use with

HI931100. Soak it in
HI7086 (Na 23 g/L) solu-

tion overnight before use
with HI931101.

If the electrolyte solution
is more than 1cm (½")
below the filling hole, add
HI 8093 1M KCl+AgCl
electrolyte solution.

Shift downwards the rub­ber sleeve during mea­surements and calibra­tion.

SODIUM MEASUREMENT

Rinse the sodium electrode tip with
some of the sample to be tested,
then immerse the tip (approx. 2.5
cm /1") in the sample and stir gen­tly.

2322

The sensitive bulb should not touch the bottom of
the beaker.

The Hanna HI 76405 electrode
holder can be used for this
purpose.

During measurement, the
sample should be gently
stirred (approx. 100 rpm). The
Hanna HI190M stirrer can be
used for this purpose.

STORAGE

When used frequently, the electrode should be stored
in a solution with a Na or NaCl concentration similar
to the sample to be measured. For longer periods of
storage, the electrode should be sored with a few
drops of appropriate solution in the protective cap.

For frequent use in different samples (1 or 2 times
per week), store the electrode in HI7081 (30.0 g/L
NaCl) solution if used for NaCl measurements with
HI 931100.

Store the electrode in HI 7080 (2.3 g/L Na) solution
if used for Na measurements with HI931101.

For occasional use (once a month or less) store the
electrode dry and let it conditioning overnight in
HI7081 (30.0 g/L NaCl) or HI7086 (23 g/L Na)
solution before use.

Note: NEVER STORE OR RINSE THE ELECTRODE

IN DISTILLED OR DEIONIZED WATER.

PERIODIC MAINTENANCE

Inspect electrode and cable. The cable used for
connection to the meter must be intact and there
must be no points of broken insulation on the cable
or cracks on the electrode stem or bulb. Connec­tors must be perfectly clean and dry.

If any scratches or cracks are present, replace the
electrode.

Rinse off any salt deposits with water.
Refill the electrode with fresh electrolyte (HI 8093)

and let it stand upright for 1 hour.
Follow the Storage Procedure above.

CLEANING PROCEDURE

General Soak in Hanna HI 7061 general clean-

ing solution for approximately 1 hour.

Removal of films, dirt or deposits on the membrane/
junction:

-

Protein

Soak in Hanna HI 7073 protein clean­ing solution for 15 minutes.

-

Inorganic

Soak in Hanna HI 7074 inorganic clean­ing solution for 15 minutes.

-

Oil/grease

Rinse with Hanna HI 7077 or Oil & Fat
cleaning solution.

IMPORTANT: After performing any of the clean­ing procedures rinse the electrode thoroughly
with a solution containing 2% ISA, refill (if
necessary) the reference chamber with fresh
electrolyte (HI8093) and soak the electrode in

a solution very close to the next sample to
be measured for at least 1 hour before taking

measurements.

TROUBLESHOOTING

Evaluate the performance of your electrode based
on the following.

• Noise (readings fluctuate up and down) could be
due to:

- Clogged/Dirty Junction: refer to the Cleaning

Procedure above.

- Loss of shielding due to low electrolyte level:

refill with HI 8093 solution

• Dry Membrane/Junction: soak it overnight in
HI7081 (30.0 g/L NaCl) or HI7086 (23 g/L Na)

solution before use.

• Drifting: soak the electrode tip in warm HI8093
solution for one hour. Refill with fresh HI 8093
electrolyte solution.

• Low Slope: refer to the Cleaning Procedure.

• No Slope: check the electrode for cracks in

glass stem or bulb and, if necessary, replace
the electrode.

• Slow Response/Excessive Drift: soak the tip
in HI 7061 solution for 30 minutes, rinse thor-
oughly in a solution with 2% of ISA, and then
follow the Cleaning Procedure.
