HI9033andHI9034multi‑rangeconductivityandTDSmeters,havebeen
designed for extended use in wet, humid, dusty and muddy conditions.
These meters utilize the latest in four‑ring potentiometric technology
which has been proven to provide higher accuracy than the common
amperometric method.
HI9033 can measure conductivity in four ranges. This allows the user to
analyze samples from deionized water to brine without having to switch
or recalibrate the probe.
HI9034 measures total dissolved solids (TDS) in three ranges to offer the
highest accuracy when performing measurements in diverse applications
suchasHVAC,wastewatertreatmentandreverseosmosis.Allthreeranges
can be activated at the touch of a button without having to change the
probe.
Both meters perform measurements with ATC (automatic temperature
compensation) which adjusts for the effects of temperature.
These portable instruments also feature BEPS (Battery Error Prevention
System) technology that alerts the user when low batteries could affect
the readings.

OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied complete with a 3x1.5V batteries. Remove the
back cover, unwrap the battery and install it while paying attention to
its polarity (see "Battery Replacement" section).
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 (i.e. the end nearest to the cable).
Make sure that the meter has been calibrated before taking any
measurements (see "Calibration" section for details).
If probe is not connected, the LCD will displays ''‑‑‑'' on both LCD lines.
TAKING MEASUREMENTS
To take measurement, place the probe into
the solution to be tested while making sure
that the holes are completely submerged. Tap
and stir the probe to remove any air bubbles
trapped inside the PVC sleeve.
Turn the instrument on by pressing the
ON/OFF key, and then select the desired range
by pressing the corresponding key.
The instrument will display all used tags for
few seconds followed by the battery capacity.

10
If the probe is not connected the instrument will
display dash lines.
If the LCD displays range limit blinking, the meter
is out of range and the solution measured exceeds
the selected range. In this case, the next (higher)
range should be selected.
TEMPERATURE EFFECT
HI76302W conductivity probe features
a built‑in temperature sensor that allows
automatic compensation of the reading for
any temperature differences.
Wait for a few minutes for the temperature sensor to reach the thermal
equilibrium with the test solution before taking measurements. If the
temperature of conductivity probe and solution is drastically different,
a longer time should be allowed.
AFTER MEASUREMENTS
When all measurements are completed, turn the meter OFF and clean
the probe (see "Probe Maintenance" section for details).
Note: 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 this case, the probe will need to be replaced.

11
CALIBRATION
For best results, choose a calibration solution with a conductivity or TDS
value as close as possible to the sample to be measured.
For example, for measurements in the 2 to 20 mS/cm range, use the
HI7030 (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.
If possible, use plastic beakers to minimize any EMC interference.
For a complete list of Hanna Instruments calibration solutions see the
"Accessories" section.
PROCEDURE FOR HI9033
•Fill a beaker with 8 cm (3¼") of conduc‑
tivity calibration solution (if possible fill
two beakers, one for rinsing the probe and
one for calibration).
•Connect the probe 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, while
paying attention that the holes on the PVC
sleeve are completely submerged.
•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 remain trapped inside the sleeve.
•If the probe temperature is close to the solution temperature, the
display will stabilize quickly and show the temperature compensated
conductivity measurement.
However, the ATC circuitry needs a few minutes for temperature
compensation if the temperature difference is about 5 °C (9 °F).

12
• When the reading is stable, adjust the calibration trimmer to read
the solution conductivity value @25 °C.
For example if using HI7030, turn the trimmer to read
12.88 mS/cm @25 °C.
The calibration is now complete and the instrument is ready for use.
All subsequent measurements will be compensated to 25 °C (77 °F).
Note: Calibration can also be standardized to have readings
compensated to 20 °C (68 °F), by simply adjusting the trimmer
to the calibration solution value at 20 °C (68 °F). For example,
for HI7030 adjust the trimmer to read 11.67 mS/cm (see
"Conductivity vs. Temperature" section).
If the instrument cannot be calibrated, refer to the "Probe Maintenance"
section.
PROCEDURE FOR HI9034
•Fill a beaker with 8 cm (3¼") of TDS
calibration solution (if possible fill two
beakers, one for rinsing the probe and
one for calibration).
•Connect the probe 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, while
paying attention that the holes on the PVC
sleeve are completely submerged.
•Turn the instrument on by pressing the
ON/OFF key and select the appropriate
range (e.g. 1999 mg/L).

13
•Tap the probe repeatedly on the bottom of the beaker and stir it
to ensure that no air bubbles remain trapped inside the sleeve.
•If the probe temperature is close to the solution temperature, the
display will stabilize quickly and show the temperature compensated
conductivity measurement.
However, the ATC circuitry needs a few minutes for temperature
compensation if the temperature difference is about 5 °C (9 °F).
• When the reading is stable, adjust the calibration trimmer to read
the solution conductivity value @25 °C.
For example if using HI7032, turn the trimmer until the display
shows 1382 mg/L @25 °C.
The calibration is now complete and the instrument is ready for use.
All subsequent measurements will be compensated to 25 °C (77 °F).
Note: Calibration can also be standardized to have readings
compensated to 20 °C (68 °F), by simply adjusting the trimmer
to the calibration solution value at 20 °C (68 °F). For example,
for HI7032 adjust the trimmer to read 1251 mg/L (see "TDS
vs. Temperature" section).
If the instrument cannot be calibrated, refer to the "Probe Maintenance"
section.

The conductivity of an aqueous solution is the measure of its ability to
carry an electrical current by means of ionic motion.
The conductivity increases with increasing temperature. In fact, it is
affected by the type and number of ions in the solution, and by the
viscosity of the solution itself.
Both parameters are temperature dependent.
The dependency of conductivity on temperature is expressed as a relative
change per degree Celsius at a particular temperature, commonly as
percent per degree Celsius (%/°C).

The TDS value in aqueous solutions is directly proportional to conduc‑
tivity. The ratio between the two parameters depends on the solution
and it is usually set to a factor of 0.5 (corresponding to a solution of
CaCO3). This means that 1 µS/cm is equal to 0.5 mg/L (ppm) of TDS.

After every series of mea‑
surements, rinse the probe
with tap water.
If a more thorough cleaning
is required, remove the PVC
sleeve and clean the probe
with a cloth or a nonabra‑
sive detergent.
When reinserting the sleeve
onto the probe, be sure that
the sleeve is in the right
direction with the four holes
towards the cable end.
After cleaning the probe,
always re‑calibrate the
instrument.
The probe body is made
of PVC. For this reason it
must never come into close
contact with a heat source.
If the probe is exposed
to high temperatures, the
rings might become loose
or detached, resulting in a
serious impairment of probe
functioning. In such cases,
probe needs to be replaced.
PROBE MAINTENANCE

17
When the battery level is low, ''BATT'' log is displayed blinking on the LCD
to advise the user that approx. 1 hour of working time is left.
It is recommended to change the batteries as soon as the battery
indicator blinks (lower frequency).
To replace the batteries, follow the next steps:
• Turn OFF the instrument.
• Open the battery compartment cap (located on the top of the
instrument).
• Remove old batteries.
• Insert three new 1.5V AAA batteries in the battery compartment,
following the instructions on the rear of the instrument.
• Reattach the battery compartment cap.
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.
