PRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipping.
If there is any noticeable damage, notify your Dealer or the nearest
Hanna office immediately.

Each meter is supplied with:

• Conductivity probe with 1 m (3.3') cable

• Calibration screwdriver (HI 933000 only)

• 9V battery and instruction manual

Note: Save all packing materials until you are sure that the

instrument functions correctly. Any damaged or defective item
must be returned in its original packing materials together
with the supplied accessories.

GENERAL DESCRIPTION

HI 8033 and HI 933000 are some of the most complete and versatile
portable conductivity meters ever manufactured.

Designed with utmost precision and simplicity, these meters provide for
up to 3 or 4 measurement ranges.

The conductivity of a solution depends on the temperature and for
this reason measurements are carried out with reference to a
standard temperature of 25°C.

If the solution measured has a different temperature than 25°C,
compensation must be performed.

HI 8033 compensates for temperature manually, while HI 933000,
with a built-in temperature sensor and circuitry, automatically com­pensates for temperature changes.

The temperature coefficient is fixed at 2%.

OPERATIONAL GUIDE

CALIBRATION

• Each meter is supplied complete with a 9V battery. Slide off the
battery compartment cover on the back of the meter and install
the battery while paying attention to its polarity (see "Battery
Replacement" section for details).

• Connect the probe to the meter by aligning the pins with the
socket and pushing the plug in. With HI 933000, tighten the
threaded ring.

• Make sure that the meter has been calibrated before taking any
measurements (see "Calibration" section for details).

• Immerse the conductivity probe into the
sample, making sure that the holes on
the shaft are completely submerged.

If possible, use plastic beakers to minimize
any EMC interference.

• Tap the probe lightly on the bottom of the beaker to remove any
air bubbles which may be trapped inside the sleeve.

• Turn the instrument on by pressing the ON/OFF key or by setting
the rotary switch (HI 8033) to the desired measurement range.

• For HI 8033:

°C

Measure the solution temperature with a
ChecktempC or another accurate ther­mometer, and set the temperature knob
to the measured value (e.g. 20°C).

• Select the appropriate measurement range.

Note: If the display shows only a "1", the

meter is out of range. Select the next
(higher) range.

• For HI 933000:

Before taking any measurement, wait a couple of minutes for the
temperature sensor to reach thermal equilibrium with the sample.

When the temperature of the sample is lower than 20°C or higher
than 30°C, allow more time for the thermal equilibrium to be
achieved.

• After measurements, switch the instrument off and clean the
probe (see "Probe Maintenance" section for details).

The instrument should be re-calibrated at least once a month, or
after probe or battery replacement.

For more accurate results, it is recommended to use a calibration
solution with a conductivity value close to the range to be measured.
See the "Accessories" section for a wide selection of conductivity
solutions.

PROCEDURE FOR HI 8033

• Pour the conductivity calibration solution
(e.g. HI 7030) into a beaker while mak­ing sure that the holes on the probe are
completely submerged. If possible, use
plastic beakers to minimize any EMC in­terference.

• Immerse the conductivity probe and the
ChecktempC in the solution.

• Wait a couple of minutes for the thermal
equilibrium to be reached.

• Tap the probe on the bottom, then shake it while rotating to
make sure no air bubbles remain trapped in the sleeve.

• Measure the temperature of the calibration solution with the
ChecktempC, and adjust the °C knob accordingly.

• Turn the rotary knob to select the 19990 µS/cm range.

• Turn the k% calibration knob until the display shows the
conductivity reading at 25°C (see "Conductivity vs. temperature
chart "), e.g. 12880 µS/cm (= 12.88 mS/cm), and all
subsequent measurements will be compensated to 25°C (77°F).

• If you prefer to standardize the temperature compensation to
20°C (68°F), adjust the trimmer to read "11.67 mS" (see
"Conductivity vs. temperature chart "). All subsequent measure­ments will be compensated to 20°C.

• The calibration is now complete and the meter is ready for use.

PROCEDURE FOR HI 933000

• Pour the conductivity calibration solution (e.g. HI 7030) into a
beaker while making sure that the holes on the probe are
completely submerged. If possible, use plastic beakers to minimize
any EMC interference.

• Immerse the conductivity probe in the
solution and wait a couple of minutes for
thermal equilibrium to be reached.

• Tap the probe on the bottom, then shake
it while rotating to make sure no air
bubbles remain trapped in the sleeve.

• Switch the instrument on by pressing ON/OFF, and select the

19.99 mS/cm range by pressing the corresponding range key.

• With the supplied screwdriver, adjust the calibration trimmer in
the battery compartment until the display shows "12.88 mS", i.e.
the solution conductivity value at 25°C. All subsequent measure­ments will be compensated to 25°C (77°F).

CONDUCTIVITY VERSUS

TEMPERATURE CHART

The conductivity of an aqueous solution is the measure of its ability to
carry an electrical current by means of ionic motion.

The conductivity invariably increases with increasing temperature.
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 °C.

For manual temperature compensation, refer to the following chart:

• If you prefer to standardize the temperature compensation to
20°C (68°F), adjust the trimmer to read "11.67 mS" (see
"Conductivity vs. temperature chart "), and all subsequent mea­surements will be compensated to 20°C.

• The calibration is now complete and the meter is ready for use.

For instance, the conductivity values of the calibration solutions at

HI 7030, HI 7031 or HI 7039, respectively.

At 20°C, the values are 11670 µS/cm, 1278 µS/cm or
4523 µS/cm, respectively.

With the solutions at 30°C, the values are 14120 µS/cm, 1548 µS/cm
or 5479 µS/cm, respectively.

BATTERY REPLACEMENT

After every 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 non-abrasive
detergent. When reinserting the sleeve
onto the probe, be sure that the sleeve
is in the right direction with the holes
towards the cable end.

After cleaning the probe, 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 (above 50°C/122°F), the rings
might become loose or detached, result­ing in a serious impairment of the probe.

In such cases, the probe has to be
replaced.

When the battery becomes weak, a "V" will be displayed to warn the
user that only a few hours of working life are left.

A low battery can result in unreliable measurements. It is recom­mended to replace it immediately.

Battery replacement must only take place in a non-hazardous area,
and using an alkaline 9V battery.

Slide off the battery compartment cover (see figure below) and replace
the 9V battery with a new one.

Make sure the battery contacts are tight and secure before replacing
the cover.

Recommendations for 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 unacceptable interference to radio
and TV equipment, requiring the operator to take all necessary steps to correct interferences.

The metal rings of the probe are sensitive to electrostatic discharges. Avoid touching these rings at all times.
During calibration of the instruments, ESD wrist straps should be worn to avoid possible damage to the probe
by electrostatic discharge. Use plastic beakers to minimize any EMC interferences.

Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC
performance. To avoid electrical shock, do not use these instruments when voltages at the measurement
surface exceed 24 Vac or 60 Vdc.

To avoid damage or burns, do not perform any measurement in microwave ovens.
