MEASUREMENT PROCEDURE
• Turn the meter on by pressing
ON/OFF.
• When the LCD displays "- - -", it is
ready.
• Fill one cuvette (#1) with 10 mL
of distilled water (up to the mark).
• Fill another cuvette (#2) with 10
mL of sample (up to the mark).
Note: for low chloride ions
concentration, rinse the cuvette a couple of times with
sample before filling it with 10 mL of sample (up to the
mark).
Note: for most accurate results, use two graduated
pipettes to deliver exactly 10 mL of distilled water and
10 mL of sample to the cuvets.
• Using the 1 mL syringe, add 0.5 mL of HI 93753A-0
Displacing Reagent to each cuvet.
Note: to dose exactly 0.5 mL of reagent with the
syringe, push the plunger completely into the syringe
and insert the tip into the HI 93753A-0 Displacing
Reagent bottle. Pull the plunger out until the lower
edge of the seal is on the 0.0 mL mark of the syringe.
Then hold the syringe above the cuvet and push the
plunger down to the 0.5 ml mark.
• Replace the caps and mix each
cuvet by turning the cuvette upside
down for approximately 30 seconds.
• Remove the caps and use the second 1 mL syringe to
add 0.5 mL of HI 93753B-0 Complexing Reagent to
each cuvet.
ON
OFF
• Replace the caps and mix each
cuvet by turning the cuvette
upside down for approximately
30 seconds.
• Place the cuvet with the reacted
distilled water (#1) into the
instrument.
• Press READ TIMED and the display will show the countdown
prior to zeroing the blank or, alternatively, wait for 2
minutes and press ZERO. In both cases "SIP" will
appear during measurement.
• Wait for a few seconds and the
display will show "-0.0-”. Now
the meter is zeroed and ready
for measurement.
• Remove the cuvette.
• Place the other cuvet with the
reacted sample (#2) into the
instrument.
• Press READ DIRECT and "SIP" will blink on the LCD
during measurement.
• The instrument directly displays concentration in mg/L of
chloride on the Liquid Crystal Display.
• To convert the reading to mg/L of Sodium Chloride
(NaCl), multiply the reading by a factor of 1.65.
The instructions below should be carefully followed during
testing to ensure best accuracy.
• Do not touch the cuvette walls with your fingers.
• In order to maintain the same conditions during the
zeroing and the measuring phases, it is necessary to
close the cuvette to prevent any contamination.
• Do not let the test sample stand too long after adding
the reagents or accuracy will be compromised.
• Whenever the cuvette is placed into the measurement
cell, it must be completely free of fingerprints, oil or dirt.
Wipe it thoroughly with
HI 731318
or a lint-free cloth
prior to insertion.
• It is important that the sample does not contain any
debris. This would corrupt the readings.
• It is possible to take multiple readings in a row, but it
is recommended that a zero reading be taken for each
sample and that the same cuvette is used for zeroing
and measurement.
• It is important to discard the sample immediately after
the reading is taken because the glass might become
permanently stained.
• Shaking the cuvette can generate bubbles in the sample,
causing higher readings. To obtain accurate measure-
ments, remove such bubbles by swirling or by gently
tapping the vial.
• All the reaction times reported in this manual are
referred to 20°C (68°F). As a general rule of thumb,
they should be doubled at 10°C (50°F) and halved at
30°C (86°F).

BATTERY REPLACEMENT
Battery replacement must only take place in a non-hazard-
ous area using a 9V alkaline battery.
Simply slide off the battery cover on
the back of the meter. Detach the
battery from the terminals and at-
tach a fresh 9V battery while paying
attention to the correct polarity. Re-
place the battery and the cover.

Recommendations for
Users
Before using these products,
make sure that they are
entirely suitable for the
environment in which they
are used.
Operation of these
instruments in residential
area could cause
unacceptable interferences
to radio and TV
equipments, requiring the
operator to take all
necessary steps to correct
interferences.
Any variation introduced by the user to the supplied equipment may degrade the
instruments' EMC performance.
To avoid damages or burns, do not perform any measurement in microwave ovens.

INTERFERENCES
The pH of sample after addition of reagents should be about
2. For alkaline samples, neutralize before adding reagents.
Intensely colored samples will cause interference, therefore
they should be adequately treated before performing the
test. Suspended matter in large amounts should be re-
moved by prior filtration.
ACCESSORIES
• 2 syringes (1 mL), included in the HI 93753 reagents
set.
