DearCustomer,
Thank you for choosing a Hanna product. This manual will
provide you with the necessary information for the correct
operation of the meter. Please read it carefully before using
the meter. If you need additional technical information, do
not hesitate to e-mail us at [email protected].
This instrument is in compliance with directives.
Remove the instrument from the packing material and
examine it carefully to make sure that no damage has
occurred during shipment. If there is any damage, notify
your Dealer.
Each Ion Specific Meter is supplied complete with
• 9V Battery
• Two Sample Cuvets and Caps
• One Transport Cap
Note: Conserve all packing material until the instrument
has been observed to function correctly. Any defective
item must be returned in its original packing.
The HI 93713 meter measures phosphate (PO43–) content in
water, wastewater and seawater in the 0.00 to 2.50 mg/L
(ppm) range.
Themeter usesan exclusivepositive-lockingsystem toensure
that the cuvet is in the same place every time it is placed
into the measurement cell.
The reagents are in powder form and are supplied in
packets. The amount of reagent is precisely dosed to ensure
maximum repeatability.
Display codes aid the user in routine operations.
The meters have an auto-shut off feature that will turn the
instrument off after 10 minutes of non-use.

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
themaximum concentrationreadable (see
specifications) indicates that the sample
absorbs too much light, meaning 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.
• When the LCD displays
"- - -", it is ready.
• Fill the cuvet up to 1.5 cm
(¾") below the rim with 10
mL of sample and replace
the cap.
• Place the cuvet into the
holder and ensure that the
notch on the cap is
positioned securely into the
groove.
• Press ZERO and "SIP" will appear on the display.
• Wait for a few seconds and
thedisplaywillshow"-0.0-".
Now the meter is zeroed
andready formeasurement.
• Remove the cuvet and add
the content of one packet of
HI 93713 reagent.
• Replace the cap and shake
gently.

READ
DIRECT
• Reinsert the cuvet into the
instrument.
• PressREADTIMEDandthedisplaywillshowthecountdown
prior to the measurement, or, alternatively wait for 3
minutesand press READ DIRECT. In both cases "SIP"will
appear during measurement.
• Theinstrument directly displays concentration in mg/L of
phosphate on the Liquid Crystal Display.
• To convert the PO43– ion concentration to P2O5
concentration, multiply the reading by a factor of 1.49.
• To convert the PO43– ion concentration to Phosphate P
concentration, multiply the reading by a factor of 0.33.
INTERFERENCES
Interference may be caused by:
Iron above 50 mg/L
Silica above 50 mg/L
Silicate above 10 mg/L
Copper above 10 mg/L
Hydrogen sulfide, arsenate, turbid sample and highly
buffered samples also interfere.
READ
TIMED
The instruction listed below should be carefully followed
during testing to ensure best accuracy.
• Do not touch the cuvet walls with hands.
• In order to maintain the same conditions during the
zeroing and the measuring phases, it is necessary to
close the cuvet to prevent any contamination.
• Do not let the test sample stand too long after reagent
is added or accuracy will be lost.
• Whenever the cuvet 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 cuvet 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 cuvet 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 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 attach a fresh
9V battery while paying attention to the correct polarity.
Replace the battery and the cover.

Recommendationsfor 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 unaccept-
able 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 micro-
wave ovens.
