GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
The HI 93753 meter measures the chloride (Cl–) content in
water and wastewater in the 0 to 20 mg/L (ppm) range.
Themeter usesan exclusivepositive-locking systemtoensure
that the cuvet is in the same position every time it is placed
into the measurement cell.
The reagents are in liquid form and are supplied in bottles.
The amount of reagent is precisely dosed to ensure maxi-
mum repeatability.
Display codes aid the user in routine operations.
The meter has an auto-shut off feature that will turn the
instrument off after 10 minutes of non-use.

Method Adaptation of the mercury(II)
thiocyanate method. The chloride ion
displaces thiocyanate ion from
mercury(II).The iron(III) present forms
with thiocyanate an orange colored
complex. The intensity of color is
proportional to the chloride ion
concentration.

This indicates that the meter is in a
ready state and zeroing can be per-
formed.
Sampling in Progress. This prompt ap-
pears each time the meter is performing
a measurement.
This indicates that the meter is in a
zeroed state and measurement can be
performed.
A zero reading was not taken. Insert a
sample before adding reagent and press
ZERO.
Under range. A blinking "0.00" indicates
that the sample absorbs less light than
the zero reference. Check the procedure
and make sure you use the same cuvet
for reference (zero) and measurement.
Over range. A flashing value higher than
the maximum range (see specifications)
indicates that the sample absorbs too
much light and that the concentration is
too high. Dilute the sample.
Light over range. The cuvet is not in-
serted correctly and an excess ambient
light is reaching the detector. If the cover
is properly installed, then contact your
dealer or the nearest Hanna Customer
Service Center.
Light under range. The zero sample is
too dark for proper zeroing. If this is not
the case, contact your dealer or the
nearest Hanna Customer Service Center.
The "V" indicates that the battery volt-
age is getting low and the battery needs
to be replaced.
This indicates that the battery is dead
and must be replaced.
Note: once this indication is displayed,
the meter will lockup. Change the bat-
tery to restart.

MEASUREMENT PROCEDURE
• Turn the meter on by pressing
ON/OFF.
• Whenthe LCD displays "- - -",itis
ready.
• Fill one cuvette (#1) with 10 mL
ofdistilled 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
cuvetby turningthe cuvetteupside
downforapproximately30 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.

OFF
• Replacethe caps and mix each
cuvet by turning the cuvette
upsidedown for approximately
30seconds.
• Place the cuvet with the reacted
distilled water (#1) into the
instrument.
• PressREADTIMEDandthedisplaywillshowthecountdown
prior to zeroing the blank or, alternatively, wait for 2
minutes and press ZERO. In both cases "SIP" will
appear during measurement.
• Waitfora few seconds and the
displaywill show"-0.0-”. Now
the meter is zeroed and ready
formeasurement.
• 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.
• Theinstrumentdirectlydisplaysconcentrationinmg/Lof
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,itmustbe 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.
• Shakingthe cuvette can generate bubbles in thesample,
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.

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.
