GENERAL DESCRIPTION

HI 9033 and HI 9034 multi-range conductivity and TDS meters, have been
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.

HI 9033 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.
HI 9034 measures total dissolved solids (TDS) in three ranges to offer the
highest accuracy when performing measurements in diverse applications
such as HVAC, waste water treatment and reverse osmosis. All three ranges
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.

INITIAL PREPARATION

Each meter is supplied complete with a 9 V battery. Remove the back
cover, unwrap the battery and install it while paying attention to its
polarity its (see "Battery Replacement" section).

Connect the probe to the meter securely by
aligning the pins with the socket, pushing

3

4

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).

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.

ON/OFF

If the LCD displays only 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 selected.

TEMPERATURE EFFECT

m

HI 76302W 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 the clean the probe cleaned (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.

ON/OFF

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
HI 7030 (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 HI 9033

• 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).

ON/OFF

19.99mS/c

• 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

/l

read the solution conductivity value @25°C.
For example if using HI 7030, turn the trimmer to read

12.88 mS/cm @ 25°C.

mS

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 com-

pensated to 20°C (68°F), by simply adjusting the trimmer to
the calibration solution value at 20°C (68°F). For example, for
HI 7030 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 HI 9034

• 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).

• 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 HI 7032, 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 com-

pensated to 20°C (68°F), by simply adjusting the trimmer to
the calibration solution value at 20°C (68°F). For example, for
HI 7032 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.

CONDUCTIVITY VS. TEMPERATURE

TDS VS. TEMPERATURE

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 conduc­tivity. 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.

PROBE MAINTENANCE

BATTERY REPLACEMENT

After evry series of measure­ments, 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 nonabra­sive 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.

The meters are supplied with the ad­vanced BEPS (Battery Error Prevention
System) technology, which detects a low

V

battery condition and warn the user by
displaying the "V" symbol.

When the low battery indicator appears, the battery can support
approximately 5 hours of use.

When the battery level becomes too low to ensure reliable readings,
the instrument automatically shuts off.

Battery replacement must only take place in a safe area and using a
9V alkaline battery.

To replace the rundown battery, remove
the two screws on the rear cover of the
instrument and replace the battery with
a new one, while paying attention to
the correct polarity.

After battery replacement, always
recalibrate the meter.
