HI9033,HI9034, HI9039, HI9130,HI 933100and HI 9635are
multirangeconductivity/TDSmeters withAutomaticTemperature Com-
pensation. These meters utilize the latest in four-ring potentiometric
technology which has been proven to provide higher accuracy than
the common amperometric method.
HI 9033, HI 9130, HI 933100 and HI 9635 have a range of 0 to
199900 µS/cm (µmho/cm); HI 9034 has a range of 0 to
19990mg/L (ppm). HI 9635 can also take TDS measurements in
the 0 to 100,000 mg/L range, and temperature measurements in
the 0.0 to 60.0°C range. Thanks to this wide measurement range,
these meters can be used to analyze any sample from deionized
water to brine.
In particular, HI 9130 with its white casing and easy operation has
been specifically designed for the food industry.
HI 9039 can measure conductivity, temperature and two different
types of fertilizer concentrations (F1 and F2) for applications in
agriculture and horticulture. To measure the fertilizer content, simply
standardize the two different fertilizer ranges. To monitor the quality
of the water used with the fertilizer, the conductivity must be checked.
Thisalso helps inthe selection of water to be mixed with the fertilizer.
The temperature of all conductivity/TDS measurements is automati-
Remove the instrument from the packing material and examine it to
make sure that no damage has occurred during shipping. If there is
any damage, notify your Dealer.
Each meter is supplied complete with:
• HI 76302W Conductivity Probe with 1 m (3.3') screened cable
•9 V battery (except HI 933100 and HI 9635 which are
supplied with 4 x 1.5VAA)
•Soft carrying case (HI 9130 only)
•Hard carrying case (except for HI 9130)
Note: Save all packing materials until you are sure that the
instrument functions correctly. Any defective item must be
returned in the original package together with the supplied
accessories.

cally compensated for by the ATC circuitry of the meters. The stainless
steel rings of the probe have a large surface for better response and
easy cleaning. The detachable probe can be changed without
returning the unit to the factory. The probe cable is screened and 1
m (3.3') long.
The meters are constructed with a waterproof, rugged housing to
provide the versatility required for both laboratory and field use.
Another feature of the meters is the Battery Error Preventive System
(BEPS) which prevents erroneous readings due to low battery voltage.
Moreover, HI 9039,HI 933100 and HI 9635 are equipped with a
large LCD that helps the user through operation and calibration with
large comprehensive symbols. Besides displaying the selected range,
the LCD simultaneously displays the temperature. These meters are
microprocessor-based and perform buffer recognition and calibration
automatically.
For continuousmonitoring HI 933100andHI 9635are suppliedwith
built-in 12VDC sockets protected behind a waterproof cover.
The temperature coefficient of HI 933100 and HI 9635 is user-
selectable from 0.0 to 3.0%. The TDS/conductivity ratio (factor) of
HI 9635 can be set to 0.7 (F1) or 0.5 (F2).

INITIAL PREPARATION
Each meter is supplied complete with battery(ies). Remove the back
cover, unwrap the battery(ies) and install it (them) while paying
attentiontopolarityits(their)(see page 31).
Connect the probe to the meter securely by
aligning the pins with the socket, pushing
the plug in and tightening the threaded ring.
Make sure that the sleeve is properly inserted on the probe, with the
holes towards the top of the probe (the end nearest to the cable).
Make sure that the meter has been calibrated before taking any
measurements (see page 15).
TAKING CONDUCTIVITY/TDS MEASUREMENTS
To take a measurement, place the probe
into the solution to be tested with the holes
completely submerged. Tap and stir the
probe to remove all air bubbles that may be
trapped inside the PVC sleeve.
Turn the instrument on by first pressing the
ON/OFF key and then selecting the desired range
(not HI 933100 and HI 9635).
With HI 9039, press RANGE to choose the range. "F1" and "F2" will
appear to show the first or the second fertilizer range.
With HI 9635, press RANGE to select the desired
mode, which can be one of the following:

• TDS1 mode: TDS with 0.7 factor (shown
on the secondary display)
• TDS2mode:TDSwith 0.5factor(shown
on the secondary display)
In the TDS mode, by pressing FACTOR the secondary display shows
the temperature of the solution .
HI 933100 and HI 9635 are auto-ranging conductivity meters, and
the reading automatically switches from one resolution to the next.
With HI 9033, HI 9034 and HI 9130, if the
LCD displays a "1" on the far left hand side,
the meter is out of range and the solution
measured exceeds the selected range. In this
case, the next (higher) range should be se-
lected.
With HI 9039, HI 933100 and HI 9635 the
out of range prompt is given by four hyphens.
TEMPERATURE EFFECT
HI 76302W conductivity probe has a built-in temperature sensor and
automaticallycompensates forany temperature differences.Wait for a
few minutes for the temperature sensor to attain thermal equilibrium
with the test solution before taking the measurement. If the tempera-
ture of the conductivity probe and the solution is drastically different,
a longer time should be allowed before taking readings.
Once the reading stabilizes, the measurement is complete. If further
measurements are desired, rinse the probe with tap water and test
the next sample.
MANUAL TEMPERATURE COMPENSATION (FOR
HI933100 AND HI 9635)
To perform manual temperature compensation, use HI 933100
and HI 9635 with HI 76301W conductivity probe instead of the
supplied HI 76302W.
Connect HI 76301W to the meter.

The secondary LCD figure will display a default
temperature of 25°C or the last recorded tem-
perature reading with a blinking "°C" symbol.
Change the reading by pressing the UP or
DOWN keys. Hold down the UP or DOWN keys
to force the reading to change in 0.5°C steps
(HI 933100) or 1°C (HI 9635) instead of
0.1°C.
Note: IfHI76302Wisconnectedto HI933100
or HI 9635 and the °C mode is se-
lected, the secondary LCD will continue
to display the measured temperature ,
and the "°C" symbol will not blink.
PressingUP or DOWN will alsonot alter
the temperature readings.
TEMPERATURE COEFFICIENT SELECTION (FOR
HI933100 AND HI 9635)
Press FACTOR again to select the TC (Temperature Coefficient). The
secondary LCD will display the temperature coefficient (e.g. 2.0% per
°C).
This value is adjustable from 0.0 to 3.0%/°C
by pressing UP or DOWN.
AFTER MEASUREMENTS
When all measurements are completed the meter
should be turned OFF and the probe cleaned (see
page 30).
Note: The probe body and sleeve are made of PVC and are
susceptible to damage due to temperatures exceeding 60°C
(140°F). If the probe is exposed to high temperature, the
bond between the rings and the probe body may become
impaired and the probe will not function properly, in which
case, it has to be replaced.

For best results in calibrating your meter, choose a conductivity/TDS
solution that is closest in value to the sample to be measured.
For example if your measurements are in the 2 to 20 mS/cm range,
ideallyusetheHI7030 or HI8030(12880µS/cm=12.88 mS/cm)
conductivity calibration solution.
For accurate calibration, use
two beakers for each solution:
the first one for rinsing the
probe and the second one for
calibration. In this way, contamination of the calibration solutions is
minimized.
In order to minimize any EMC interference, use plastic beakers for the
solutions,whereverpossible.
A complete list of the Hanna calibration solutions is given in the
Accessoriessection(page32).
PROCEDURE FOR HI 9033 AND HI 9130
•Filla beaker with8 cm (3¼")of conduc-
tivity calibration solution (if possible fill
two beakers and use one as rinse and
the other for calibration).
•Make sure that the probe is connected to
the meter securely by aligning the pins
with the socket, pushing the plug in
and tightening the threaded ring.
•Immerse the probe into the beaker. The
level of solution must be higher than the
holes on the PVC sleeve.
•Turn the instrument on by pressing the ON/OFF key and select
the appropriate range (e.g. 19.99 mS/cm).
•Tap the probe repeatedly on the bottom of the beaker and stir it
to ensure that no air bubbles are trapped inside the sleeve.
•If the temperature of the probe is close to that of the solution, the
display will stabilize quickly and provide you with temperature
compensated conductivity measurements. However, allow a few

minutes if there is a temperature difference of 5°C (9°F) or more
for the ATC circuitry to compensate completely.
•When the reading stabilizes, turn the calibration trimmer until
the display reads the proper conductivity value @25°C.
For example with HI 7030/HI 8030 turn the trimmer to read
12.88 mS/cm@ 25°C.
Note: It is also possible to standardize the calibration to have
readings compensated to 20°C (68°F) rather than 25°C
(77°F). During the calibration, as explained above, simply
adjust the trimmer to the calibration buffer reading at 20°C
(68°F). For example, for HI 7030 / HI 8030 this value is
11.67 mS/cm and can be found on the conductivity vs.
temperature chart on page 22.
The calibration is now complete and the instrument is ready for use.
All subsequent measurements will now be compensated to 25°C
(77°F).
If the instrument cannot be calibrated refer to the Probe Maintenance
section (page 30).
You can calibrate the instrument using any other Hanna calibration
solution in exactly the same way. For example with HI 7031 /
HI 8031 turn the trimmer to obtain 1413 µS/cm @25°C.
PROCEDURE FOR HI 9034
•Fill a beaker with 8 cm (3¼") of TDS
calibration solution (if possible fill two
beakers and use one as rinse and the
other for calibration).
•Make sure that the probe is connected to
the meter securely by aligning the pins
with the socket, pushing the plug in and
tightening the threaded ring.
•Immerse the probe into the beaker. The
level of solution must be higher than the
holes on the PVC sleeve.

•Turn the instrument on by pressing ON/OFF and select the
appropriate range (e.g. 1999 mg/L).
•Tap the probe repeatedly on the bottom of the beaker and stir it
to ensure that no air bubbles are trapped inside the sleeve.
•If the temperature of the probe is close to that of the solution, the
display will stabilize quickly and provide you with temperature
compensatedTDS measurements.However, allowa few minutes if
there is a temperature difference of 5°C (9°F) or more for the ATC
circuitry to compensate completely.
•When the reading stabilizes, turn the calibration trimmer until
the display reads the proper TDS value @25°C.
For example, when calibrating with HI 7032 turn the trimmer to
read 1382 mg/L @25°C.
Note: It is also possible to standardize the calibration to have
readings compensated to 20°C (68°F) rather than 25°C
(77°F). Simply adjust the trimmer to the calibration buffer
reading at 20°C (68°F). For example, for HI 7032 this value
is 1251 mg/L and can be found on the TDS vs. temperature
chart on page 23.
The calibration is now complete and the instrument is ready for use.
All subsequent measurements will now be compensated to 25°C
(77°F).
If the instrument cannot be calibrated, refer to the Probe Mainte-
nance section (page 30).
You can calibrate the instrument using any other Hanna calibration
solution in exactly the same way. For example with HI 7038 turn the
trimmer to obtain 6.44 g/L @25°C.

PROCEDURE FOR HI 9039
•Fillabeakerwith8cm(3¼") of HI7039
or HI 8039 conductivity calibration solu-
tionat 5000µS/cm @25°C(if possible
fill two beakers and use one as rinse and
the other for calibration).
•Make sure that the probe is connected to
the meter securely by aligning the pins
with the socket, pushing the plug in and
tightening the threaded ring.
•Immerse the probe into the beaker. The
level of solution must be higher than the
holes on the PVC sleeve.
•Turn the instrument on by pressing ON/OFF and select the
conductivity measurement mode by pressing RANGE.
•Tap the probe repeatedly on the bottom of the beaker and stir it
to ensure that no air bubbles are trapped inside the sleeve.
•Press CAL to display "5000 µS" together with the "CAL" symbol
and an intermittent "BUF" indicator.
•If the reading is within 15% of the theoretical value, the meter
automatically recognizes the standard solution and the "BUF"
symbol will stop flashing.
•"" will disappear from the display
when the reading is stable and the
"CON" symbol will start blinking.
•Press CFM to confirm the calibration reading.
Calibration is now complete and the instrument is
ready for use. All subsequent measurements will
now be compensated to 25°C (77°F). If the
instrument cannot be calibrated refer to the
Probe Maintenance section (page 30).
Press CAL to quit the calibration mode.
