OPERATIONAL GUIDE
INITIAL PREPARATION
The instruments are supplied complete with batteries. For placing the
batteries inside the meter, see page 14.
To prepare the instrument for use, connect the sodium sensitive
electrode FC300B to the input socket on the top of the instrument.
Connect the temperature probe to the temperature socket too. The
temperature probe can be used independently to take temperature
measurements. If the probe is disconnected, 25.0 °C (72.0 °F) is
displayed with °C or °F symbol blinking.
Turn the instrument ON by pressing On/Off.
At start-up the display will show all
the used segments for a few seconds (or
while the button is held), followed
by the percentage indication of the
remaining battery life. The meter is
now ready to operate.
After measurement switch the instrument off, and remove the electrodes.
For a fast and accurate measurement, 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.
The auto-off feature turns the instrument off after a set period
(default 20 min) to save battery life. To set another period or to
disable this feature, see SETUP menu on page 11.
In order to take accurate measurements, make sure the instrument is calibrated before use (see page 11 for HI 931101 and
page 13 for HI 931100 & HI 931102).
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, 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).

TAKING SODIUM MEASUREMENTS
Remove the protective cap of the FC300B
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
(2.5cm/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)
measurements
Press the MODE key during measurement to convert the displayed
value of HI931101
to pNa.
pNa = -log a
Na
where a
Na
is the activity of ion
Na.
Page 10
10
Press the MODE key during measurement to convert the displayed value of
HI931102
to %.
Press the same key to return to g/L
measurements.
AFTER USE
Turn the meter off by pressing the ON/OFF
key again.
For a faster and accurate measure, 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 electrode dry. Before using it again,
let it condition overnight in HI7081/HI8081
(30.0 g/L NaCl) or
HI7086/HI8086 (23 g/
L Na 1M).
To avoid very long response time, do not store or rinse the
electrode with deionized water. Never rub or blot the electrode.
TEMPERATURE MEASUREMENT
The temperature can be measured independently.
• Immerse the temperature probe at
least 1 cm (½”) in the prepared sample.
• Wait for the reading to stabilize. The
temperature of the solution will be shown
on the lower part of the display.
Notes: • If the temperature is out of
range, the last range value
will be displayed and the
“°C” (“°F”) tag will blink.
• If the temperature probe is not connected, the 25.0 °C
value will be displayed together with the blinking tags
“No Temp Probe” and “°C” (“°F”).
Page 11

CALIBRATION
In order to obtain accurate measurements, frequent calibration is
recommended.
For better results, calibrate at a temperature close to that of the
solution to be tested (no more than ±3°C apart).
The instrument can be calibrated in 1 or 2 points. Two-point
calibration is always recommended for better accuracy.
The user can select the calibration stability criteria in Setup menu in
accordance with the application. “ACCU” - accurate is recommended.
Note: For best results, it is recommended to prepare two beakers for
each calibration point: the first one to rinse the probes and
the second one to calibrate.
Note: It is recommended to use clean plastic beakers.

It is also possible to calibrate just the offset (2.3 g/L Na) following
the single point calibration 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 going 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 content (over 2.3 g/L).
• For accurate calibration use two
beakers for each buffer calibration, the first one for rinsing the
electrode, the second one for calibration. This way, contamination 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.

HOW TO MEASURE SODIUM CHLORIDE IN CHEESE AND
MEAT (HI931100 & HI931102)
1. Take a sample of cheese or meat to be
analyzed.
2. Grind the sample.
3. Pour a quantity of X g in a glass beaker.
Add (X)x10mL of deionized water (note:
ignoring water content in cheese and meat).

4. Cover the beaker to prevent any spilling during stirring, place
the beaker on the top of a hot plate stirrer and agitate the
sample at 40-50°C (104-122°F) for 15-20 minutes.
5. Let the sample cool to the ambient temperature, then filter it.
6. Dip the sodium electrode FC300B into the filtered sample. The
tip of the electrode should be immersed for approximately
2.5cm/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).
7. Wait for the reading to stabilize, i.e. no drift for at least a
couple of minutes.
Take note of the measured value.
8. 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 it can be considered the value
directly expressed in % of NaCl.
NoteNote
NoteNote
Note: 10 to 15 minutes as response time, in the first measure-
ment taken in samples of cheese or meat, is the right
amount of time needed by the electrode to stabilize. The
next measurements in cheese or meat samples will have a
shorter response time (less than 2 minutes). Do not rinse
the sodium electrode between measurements since contamination is negligible.

TEMPERATURE CALIBRATION
(for technical personnel only)
IONIC STRENGTH ADJUSTER (ISA)
It is recommend the use of HI7090 ISA solution when the NaCl
concentration of the sample is lower than 5 g/L. In such case, the
calibration of the meters should be performed with standard solution
containing 2% of ISA.
ISA (Ionic Strength Adjuster) = 50% of NH4 Cl 4M +50% of NH
4
OH 4M (use 2mL of ISA every 100 mL of sample).
TEMPERATURE
The best working temperature is around 20-25°C (68-77°F).
For greatest accuracy, we suggest to 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).
Na CONCENTRATION WITH HI 931100 AND HI 931102
It is always possible to determine the Na concentration by using the
formula:
XNa = X
NaCl
• (23 / 58.4)
where
XNa = Na concentration
and
X
NaCl
= NaCl concentration
All the instruments are factory calibrated for temperature.
Hanna’s temperature probes are interchangeable and no tempera-
ture calibration is needed when they are replaced.
If the temperature measurements are inaccurate, temperature
recalibration should be performed.
For an accurate recalibration, contact your dealer or the nearest
Hanna Customer Service Center, or follow the instructions below.
• Prepare a vessel containing ice and water and another one containing
hot water (at approximately 50 ºC or 122 ºF). Place insulation
material around the vessels to minimize temperature changes.
• Use a calibrated thermometer with a resolution of 0.1 ºC as a
reference thermometer. Connect the HI 7662 temperature probe
to the appropriate socket.
• With the instrument off, press and hold down the CAL & Setup
keys, then power on the instrument. The “CAL” tag will appear
and the secondary LCD will show “0.0 ºC”. The primary LCD will
display the measured temperature or the ”----” message, if the
measured temperature is out of range.
Page 19
19
• Submerse the temperature probe into the vessel with ice and
water as close as possible to the reference thermometer. Allow a
few seconds for the probe to stabilize.
• Use the Select key to set the reading on the
secondary LCD to that of ice and water, measured
by the reference thermometer. The value can be
changed in a circling way in the ±2.0 °C
interval, around the selected point. When the
reading is stable and close to the selected calibration point, “CFM” tag will blink.
• Press CFM to confirm. The secondary LCD will
display “50.0 ºC”.
• Submerse the temperature probe into the sec-
ond vessel as close as possible to the reference
thermometer. Allow a few seconds for the probe
to stabilize.
• Use the Select key to set the reading on the
secondary LCD to that of the hot water. The
value can be changed in a circling way in the
±2.0 °C interval, around the selected point.
• When the reading is stable and close to the
selected calibration point, “CFM” tag will blink.
• Press CFM to confirm. The instrument returns to
measurement mode.
Note: If the reading is not close to the selected point, “WRONG” tag
will blink. Change the temperature probe and restart calibration.

If the batteries become weak, the display will flash the battery symbol
to advise the user that approx. 1 hour of working time is left.
It is recommended to replace the batteries soon.
To replace the batteries, follow the next steps:
• Turn the instrument OFF.
• Open the battery compartment cap (located on the top of the
instrument).

The instrument is provided with the BEPS (Battery Error Prevention
System) feature, which automatically turns the instrument off when
the batteries level is too low to ensure reliable readings. At start up
the display will show “0 bAtt” message for a few seconds, then the
instrument automatically turns off.

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 overnight in HI 7081 NaCl
30.0 g/L solution before using with the
HI 931100 or HI931102 sodium meter.
Soak it overnight in HI7086 or HI8086 Na
23 g/L solution before using with the
HI931101 sodium meter.
If the fill solution (electrolyte) is more than
1cm (½") below the fill hole, add HI8093
1M KCl+AgCl Electrolyte Solution.
Lower the rubber sleeve during measurements and calibration.
SODIUM MEASUREMENT
Rinse the sodium electrode tip with
some of the sample to be tested to
remove any contamination.
Immerse the tip (2.5 cm /1") in
the sample and stir gently.
The sensitive bulb should not touch
the bottom of the beaker.
The Hanna HI76405 electrode
holder can be used for this purpose
(see page 35).
During measurement, the sample
should be gently stirred (approx.
100 rpm). The Hanna HI190M
stirrer can be used for this purpose
(see page34).

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
capped with a few drops of appropriate solution.
For frequent use in different samples (1 or 2 times per week), store
the electrode in HI 7081 or HI 8081 (30.0 g/L NaCl) if used for NaCl
measurements (in conjunction with HI 931100 or HI 931102).
Store the electrode in HI 7080 or HI 8080 (2.3g/L Na) if used for
Na measurements (in conjunction with HI 931101).
For occasional use (once a month or less) store the electrode dry and
let it conditioning overnight in HI 7081 or HI 8081 (30.0 g/L NaCl)
or HI 7086 or HI 8086 (23 g/L Na) before use.
Note: NEVER STORE OR RINSE THE ELECTRODE IN DIS-
TILLED OR DEIONIZED WATER.
PERIODIC MAINTENANCE
Inspect the electrode and the 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 (HI8093) and let it stand
upright for 1 hour.
Follow the Storage Procedure above.
CLEANING PROCEDURE
General Soak in Hanna HI7061 or HI8061 General
Cleaning Solution for approximately 1 hour.
Removal of films, dirt or deposits on the membrane/junction:
- Protein Soak in Hanna HI7073 or HI8073 Protein
Cleaning Solution for 15 minutes.
- Inorganic Soak in Hanna HI7074 or HI8074 Inorganic
Cleaning Solution for 15 minutes.
- Oil/grease Rinse with Hanna HI7077 or HI8077 Oil and
Fat Cleaning Solution.
IMPORTANT: After performing any of the cleaning procedures rinse the
electrode thoroughly with a solution containing 2% ISA (see page 22),
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.
NEVER RUB OR BLOT DRY THE ELECTRODE.
