HI8417, HI8519, HI8520 and HI8521 Hanna Instruments bench-
top pH meters are designed for simplicity of use.
They feature: large liquid crystal display (LCD), user friendly key-
board, error codes to guide the user in calibration and troubleshooting
and storage of calibration data even after the unit is shut off.
HI8417, HI8519 and HI8521 can also measure ion concentration
(ISE) and ORP in the mV range (with automatic range switching from
ISE to ORP when reading exceeds ±399.9mV, HI8417 and HI8521
only).
All models, except for HI8519, are microprocessor-based and
provide automatic or manual temperature compensation for
both calibration and measurement.
These models meet the most stringent demands of the laboratory:
HI8417 pH/mV/°C meter automatically recognizes six standard
calibration buffer values-three each for NBS (pH 4.01, 6.86, 9.18)
technical standard calibration buffers (pH 4.01, 7.01, 10.01).
A recorder output of 0 to 2 Volts is available and the wide mV range
and high resolution allow for ORP or ion-selective measurement.
HI8417 comes supplied with HI1131B glass-body combination pH
electrode, HI7669/2W temperature probe (with 1 meter / 3.3' cable),
12VDC adapter (HI710005 or HI710006) and a dust cover.
HI 8519 pH/mV meter includes: manual temperature compensation
and front panel knobs for offset and slope calibration.
HI8519 comes supplied with HI1332B plastic-body combination pH
electrode, 12VDC adapter (HI710005 or HI710006) and a dust
cover.
GENERAL DESCRIPTION
PRELIMINARY EXAMINATION
Remove the instrument from the packing material and examine it to
make sure that no damage has occurred during shipping. If there is
any damage, notify your dealer.
Note: Save all packing material until you are sure that the instru-
ment functions correctly. All defective items must be returned
in the original packing with the supplied accessories.

HI8520 pH/°C meter automatically recognizes 3 standard calibration
buffer values (4.01, 7.01 and 10.01 pH).
HI8520 comes supplied with HI1332B plastic-body combination pH
electrode, HI7669/2W temperature probe (with 1 meter/ 3.3' cable),
12VDC adapter (HI710005 or HI710006) and a dust cover.
HI8521 pH/mV/°C meter automatically recognizes 3 standard cali-
bration buffer values (4.01, 7.01 and 10.01 pH).
HI8521 comes supplied with HI1332B plastic-body combination pH
electrode, HI7669/2W temperature probe (with 1 meter/ 3.3' cable),
12VDC adapter (HI710005 or HI710006) and a dust cover.

Push the OFF key before unplugging instrument. If unplugged before
turned off, the meter's memory will be erased).
CAL To enter the calibration mode.
CON To confirm the calibration data.
°C / °C To set temperature for manual compensation.
pH/mV To select mV for mV, ORP or ISE measurements
or pH for pH measurements.
Large LCD on the left
This LCD displays the temperature measured by the HI7669/2W
probe or the value set manually with the keyboard. If the tempera-
ture has been set manually, the "°C" symbol will flash. When the
temperature probe is connected the "°C" symbol stops flashing. When
the temperature measured by the probe is out of range (-10 /
+125°C), the "Err3" signal appears.
Large LCD on the right
This LCD displays the pH or mV reading. The corresponding pH or mV
symbol will be displayed along with the measured value. An error
signal ("Err1", "Err2", "Err4" or "Err5") will appear on this display to
indicate when the range is exceeded or if the buffer during calibration
is wrong.

6. DC Power Socket (for HI710005 or HI710006).
Electrode and probe connections
For combination pH or ORP electrodes (with internal reference) plug
the electrode's BNC to the socket provided (#1).
For an electrode with a separate reference, connect the measuring
electrode's BNC to the BNC socket (#1) and the reference electrode's
jack to the socket provided (#2).
For temperature measurements and automatic temperature com-
pensation connect the temperature probe to the °C socket (#5).
Recorder Output
HI8417 is provided with a recorder output from 0 to 2 volts. Connect
the recorder output (#4) and select the pH or mV range by pressing
the pH/mV key. The output signal is related to the values as follows:
pH output: 0.01 pH = 1.42857 mV
e.g. 0.00 pH = 0 mV
7.00 pH = 1000 mV
14.00 pH = 2000 mV
mV output: 0.1 mV= 0.05 mV
e.g. -1999 mV = 0 mV
0.0 mV = 1000 mV
+1999 mV = 2000 mV
The output impedance is 100 ohms. The maximum output short-
circuit current is 20 mA.
RESET button
The RESET button (#3) is used when the instrument displays errone-
ous messages due to strong electrical interference or when the

7
instrument's power supply is disconnected before the meter is switched
off. Press the RESET button and restart the entire operation.
Power connection
Plug the 12VDC adapter (HI710005 or HI710006) into the DC socket
(#6).
Note: Make sure the main line is protected by a fuse.
Note: HI8417 uses a rechargeable battery to retain the pH calibra-
tion 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).
