GENERAL DESCRIPTION
The HI933300 and HI933301 are multirange
conductivity meters equipped with printer and
datalogger (HI933300 only).
The measurement interval is user-selectable
from 1 to 180 minutes, and the temperature
coefficient βcan vary from 0.0 to 3.0%/°C.
These microprocessor-based meters provide
automatic calibration with 5 memorized val-
ues:
• 0 µS/cm (µmhoS/cm)
• 84 µS/cm (µmhoS/cm)
• 1413 µS/cm (µmhoS/cm)
• 12880 µS/cm (µmhoS/cm)
• 80000 µS/cm (µmhoS/cm).
This makes the calibration procedure ex-
tremely simple.
HI933300 can also log and directly print the
conductivity and temperature measurements.
PRELIMINARY EXAMINATION
Remove the instrument from the packing ma-
terial and examine it to make sure that no
damage has occurred during shipping. If there
is any damage, notify your Dealer.
Eachprinting/loggingconductivitymeterissup-
pliedcompletewith:
• HI 76302W Conductivity Probe with
1 m(3.3')screenedcable
• AA size Alkaline Batteries (4 pcs)
• Paperroll (10 pcs)
•Ruggedcarryingcase
Note: Save all packing materials until you are
sure that the instrument functions cor-
rectly. All defective items must be re-
turnedintheoriginalpackagingtogether
with the supplied accessories.

The stored data can be retrieved at a later
time for printing or can be transferred to a
computer through an optional HI9200 infrared
transmitter. The HI933300 will transfer the
data in seconds through the infrared lights
with no need for a cable between the trans-
mitter and the meter.
The internal software allocates memory space
to store up to 8,000 readings.
The meters provide automatic temperature
compensation with the supplied HI76302W
4-ring probe with integrated temperature sen-
sor. The sensors in the meter's probe utilize
the latest technology in conductivity mea-
surement.
The four-ring potentiometric method incorpo-
rated into the probe has been proven to pro-
vide higher accuracy than the more common
amperometric method.
HI933300 and HI933301 have a range of 0 to
199900 µS/cm and can be used in any sample
from deionized water to brine.
The probe's stainless steel rings have a large
surface for better response and ease of clean-
ing.
The meters are equipped with an automatic
shut-off system and a 12VDC socket for maxi-
mum versatility in both laboratory and field
use.
Other features include: on-board time and
date, calibration factors stored in Eprom, au-
tomatic low battery alert system.

OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied com-
plete with batteries. Remove
the back cover, unwrap the
batteries and install them while
paying attention to their po-
larity.
To prepare the instrument for
use, connect the probe to the
meter securely by aligning the
pins with the socket located
on the top of the instrument,
pushing the plug in and tight-
ening 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).
To turn the HI933300 on,
press the RANGE key.
To turn the HI933301 on,
press the ON/OFF key.
The meter will display the clock time as 0:00
and a default sampling interval of 1 minute.

TAKING CONDUCTIVITY MEASUREMENTS
Make sure that the meter has been cali-
brated before taking any measurements (see
page 18).
To take a measurement, place the probe
into the solution with the
holes completely sub-
merged. Tap and stir the
probe to remove all air
bubbles that may be trapped
inside the PVC sleeve.
HI933300 and HI933301 are
auto-ranging conductivity meters, and the
reading automatically switches from one
resolution to the next, from pure water @
0.1µS/cm up to 199900µS/cm.
If the LCD displays four
dashes, the meter is out of
range.
HI76302W conductivity probe has a built-in
temperature sensor and automatically com-
pensates for any temperature variation.
Wait for a few minutes for the temperature
sensor to attain thermal equilibrium with the
test solution before taking the measurement.
If the temperature of the conductivity probe
and the solution is of considerable difference,
a longer time should be allowed before taking
readings.
CAL CFM
or

mS
Once the reading stabilizes
the measurement is complete.
If further measurements are
desired, rinse the probe with
tap water and test the next sample.
Note: The probe body and sleeve are made
of PVC and are very susceptible to
damage due to temperatures exceed-
ing 50°C (122°F).
If the probe is exposed to high tem-
perature, the bond between the rings
and the probe body may become im-
paired and the probe will not function
properly, in which case it has to be
replaced.
TAKING TEMPERATURE MEASUREMENTS
Taking temperature measurement with
HI933300 and HI933301 is very easy.
Press the RANGE key until the display shows
the °C mode.
Simply immerse the probe
into the sample and allow the
reading to stabilize.

scribed at page 48.

CONDUCTIVITY CALIBRATION
It is recommended that HI933300 and
HI933301 are calibrated frequently for great-
est accuracy, especially when used often or
in samples with widely differing conductivity
values. For best results choose conductivity
solutions that are closest in value to the
sample to be measured.
For accurate calibra-
tion, use two bea-
kers for each solu-
tion: the first one for
rinsing the probe,
the second one for
calibration. In this way cross contamination
is minimized.
If possible, to minimize any EMC interfer-
ences, use plastic beakers for the solutions.
These meters can also be calibrated in air at
0.0µS/cm.
For example if your measurements are in the
2 to 20 mS/cm range you should use HI7030
or HI 8030 (12880µS/cm=12.88 mS/cm) con-
ductivity calibration solution.
A complete list of all the Hanna Instruments
calibration solution is given in the Accesso-
ries section (see page 50).
Press the RANGE key to se-
lect the conductivity measure-
ment mode.
Ensure that the probe is con-
nected to the meter securely.
Insert the probe into the PVC sleeve with the
holes towards the top (the end nearest to the
cable) of the probe.
