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.
Each pH meter comes supplied complete with:
•HI 1131B glass-body combination pH electrode
•HI 7669/2W temperature probe
•HI 3131B glass-body platinum ORP electrode
•pH 4.01 & 7.01 buffer solutions (20 mL each)
•12VDC adapter (HI710005 or HI710006)
•5 paper rolls (pH 302 only)
The KIT version includes also:
•HI76405 electrode holder
•HI 92000 Windows®compatible applica-
tion software
•HI 920010 PC connection cable
•Storage, cleaning and electolyte solutions
Note: Save all packing material until you are
sure that the instrument functions correctly. All
defective items must be returned in the original
packing with the supplied accessories.
Hanna Instruments pH300,pH301 and pH302
are professional bench-top pH meters for pH,
ORP (Oxidation Reduction Potential), ISE and
temperature measurements. Their built-in mi-
croprocessor ensures accurate and user-
friendly operation.
pH measurements are automatically compen-
sated for the temperature effect (ATC).
These meters come equipped with a large,
easy-to-read LCD which shows the pH or
mV or ION (for pH301 only) with tempera-
ture simultaneously. The display has graphic
symbols to make the calibration procedure
easy to follow. Calibration is not allowed until
the electrode has stabilized to ensure accu-
rate measurements.
Through the RS 232 serial port you can
transfer sample measurements to a PC.

plied with the meters) that use the proper
polarity configuration.
The meters can also be used with other adapt-
ers. In this case, remember to check the
correct polarity of your adapter before con-
necting it to the meter.
Note: Make sure the main line is protected
by a fuse.
Press ON to turn the meter on. The power
LED will remain lit until OFF is pressed to
turn the meter off.
When the meters are turned on, the micro-
processor checks if any calibration data is in
memory (i.e. if the offset is within ±60mV
and the slope between 70-108%).
If the calibration data is
valid, the meter will op-
erate in the normal mea-
surement mode and de-
fault to pH measurement
mode with the tempera-
ture on the secondary LCD.
If the calibration data is
not valid or the calibra-
tion data is lost, the
"CAL" indicator will be
displayed to prompt the
user to perform the pH
calibration. If the user chooses not to per-
form the calibration and presses CAL to quit
from the calibration mode, the offset and the
slope of the instrument would be set to 0 mV
and 100% respectively.

OPERATIONAL GUIDE
ELECTRODE AND PROBE CONNECTIONS
For combination pH or ISE or ORP elec-
trodes (with internal reference) plug the
electrode's BNC to the socket provided (see
page 11).
For electrode with separate reference, con-
nect the measuring electrode's BNC to the
BNC socket and the reference electrode's
plug to the socket provided (see page 11).
For temperature measurements and auto-
matic temperature compensation connect the
temperature probe to the °C socket (see
page 11).
If the temperature probe
is not connected, when
turned on, the meter will
display a default tem-
perature of 25°C or the
last recorded tempera-
ture (if the temperature probe is disconnected
when the meter is on) on the secondary
LCD. The "°C" indicator will be flashing.
POWER CONNECTION
Plug the 12VDC adapter (HI710005 or
HI710006) into the DC socket (see page11).
Plug the adapter to the mains.
Note: The instrument uses the following con-
figuration.
It is recommendable to use the Hanna
HI710005 or HI710006 voltage adapters (sup-

pH300, pH301 and pH302 use an EEPROM
to retain the pH calibration, mV calibration,
temperature calibration as well as the serial
communication setting. The instrument will
store the respective data after a calibration
or serial communication setting, even when it
is not plugged-in.
For pH 302 only
pH302 uses a rechargeable battery to retain
the pH calibration data. It lasts approximately
one month when fully charged. The battery is
automatically charged any time the meter is
plugged-in (either turned on or off).
If you need to unplug the
instrument, press OFF before
disconnecting the meter from
the mains. Only in this case
will the instrument retain the
memorized data. Otherwise,
the instrument needs to be
re-calibrated. In the case of a power failure
while the instrument is operational, re-cali-
bration is required.
When the instrument is initially switched on,
the microprocessor checks if any calibration
data is in memory (i.e. if the offset is within
±1 pH and the slope between 70 - 108%).
If the calibration data are not memorized, the
offset and slope of the instrument will be set
to 0 mV and 100% respectively.
