GENERAL DESCRIPTION
HI 8614/HI 8614L (pH) and HI 8615/HI 8615L
(ORP) are 2-wire water-resistant transmitters
specially designed for long distance mea-
surement of pH or ORP in industrial applica-
tions.
Two versions are available: the standard
HI8614 and HI8615, and the HI8614L and
HI8615L models with LCD.
The LCD allows easy verification and moni-
toring of measured values, and provides easier
calibration and maintainance.
The pH or ORP signal is transmitted in a 2-
wire current loop in the range of 4 to 20 mA.
HI8614 and HI8614L can be connected to
the Hanna process instruments HI8510T,
HI8710T or HI8711T, or to any recorder,
computer or data monitoring device that ac-
cepts 4 to 20 mA input.
HI8615 and HI8615L can be connected to
the Hanna meters HI8512T, HI8720T or to
any recorder, computer or data monitor that
accepts 4 to 20 mA input.

pH
The transmitters use a universal BNC socket
for quick and secure connection to any elec-
trode with a BNC connector.
For HI8614 and HI8614L the temperature
compensation is performed by the transmitter's
ATC circuitry if the temperature probe
(HI76608, optional) is attached. If ATC is not
required, it is possible to substitute the tem-
perature probe with a fixed resistor.
The input is isolated from the current loop to
eliminate problems related to ground loop,
low insulation cables, multiple electrode con-
nections, and a common mode voltage of up
to 100 V ensures true differential readings.
The terminal board of the transmitter provides
for connection of power supply, pH or ORP
electrodes and temperature probe (for HI8614
and HI8614L models only).
The unit is enclosed in a protective casing
conforming to IP 65 standards.

pH CALIBRATION WITH AUTOMATIC
TEMPERATURE COMPENSATION
(HI 8614 & HI 8614L)
Initial preparation
• Connect the pH electrode
to the BNC socket.
• Connect the temperature
probe to the transmitter.
Pour small quantities of pH 7.01 and pH 4.01
solution into two clean beakers.
For accurate calibration use two beakers for
each buffer solution, the first one for rinsing
the electrode, the second one for calibration.
To get accurate readings, use pH7.01 and
pH 4.01 if you are going to measure acid
samples or pH 7.01 and pH 10.01 for alkaline
measurements.
Note: with HI8614L the instruments display
can be used during calibration without
the need to connect the ammeter and
the reading is directly expressed in pH
units.

HI 7004
The wire between the transmitter and the
recorder/indicator/controller should be a PVC
insulated two wire with a wire diameter of at
least 0.7 mm. This wire is fed through one of
the smaller cable glands. The maximum dis-
tance between the power supply and the
amplifier is 300 m (1000'). It is not necessary
to use shielded cable. The transmitter is
protected against inversion of supply voltage.
Electrodeconnection:connect
theBNCofthecabletotheBNC
socket on the transmitter.

For other buffer temperatures, refer to page
13 for the appropriate mA / pH reading.
• Rinse the electrode with tap
water or distilled water and
a small amount of pH 4.01
or 10.01 buffer solution or
immerse it in the pH4 rinse
solution (2nd calibration
point). Dip the electrode and
the temperature probe into
pH 4.01 (or 10.01) calibra-
tion buffer solution, shake
briefly and wait for a few
minutes for reading to stabi-
lize.
• Adjust the slope trimmer until the amme-
ter reads 8.58 mA or the display shows
"4.01" at 25°C. For other buffer tempera-
tures, refer to page 13 for the appropriate
mA / pH reading (HI 8614L).
If you are using pH 10.01
buffer solution adjust the
slope trimmer until the am-
meter read 15.43mA at
25°C (77°F) or the value in-
dicated at page 13.
FOR HI8614L ONLY
The Display Module is factory calibrated, so
that the LCD display results are referred to
the 4-20 mA loop current (e.g. LCD displays
0.00 pH when loop current is 4.00 mA and
displays 14.00 pH when current is 20.00mA).

the pH electrode and tem-
perature probe into pH 7.01
calibration buffer solution;
shake briefly and wait for
the reading to stabilize.
Note: the tip of the elec-
trode should be sub-
merged approximately
4 cm (1½") into the
solution. The tempera-
ture probe should be
located as close to
the pH electrode as
possible.
• Adjust the offset trimmer until the amme-
ter reads 12mA or the display shows "7.01"
(HI 8614L only) if the temperature of the
buffer is at 25°C.

TEMPERATURE COMPENSATION
(HI8614 & HI 8614L only)
• Take the temperature of the
buffer solutions using a
Checktemp or a thermom-
eter with a resolution of at
least 1°.
• Connect the appropriate re-
sistor to the "TEMP.
PROBE" terminals (see
page6) depending on the
temperature of the calibra-
tion solution.
• Follow the procedure as outlined in the
calibration with automatic temperature com-
pensation and use the thermometer read-
ing to adjust the trimmer until the amme-
ter reads the value according to the follow-
ing table.
°C
Under normal application, adjustment on this
module may not be necessary.
If routine check is required, the following pro-
cedures shall be performed.
• Calibrate the transmitter module using a
ammeter, as explained in the previous
pages.
• Simulate a 4.00 mA loop current for the
transmitter (i.e. pH 0.00 as Electrode in-
put) and check for display reading.
• Simulate a 20.00 mA loop current for the
transmitter (i.e. pH 14.00 as Electrode
input) and check for display reading.
Note: when the instrument is used in con-
junction with the Hanna indicator
HI 8510T or controllers HI 8710T,
HI 8711T, the calibration can also be
performed on the indicator/controller.
In this case slight calibration adjust-
ment can be made on the indicator/
controller even if the whole system cali-
bration is advised, always starting from
the transmitter.

SLOPE ADJUSTMENT
OFFSET ADJUSTMENT
• If the reading lies outside
this range, adjust the slope
adjustment trimmer on the
transmitter for a reading just
within this range.
The unit is now calibrated.
A complete calibration of the transmitter mod-
ule is advised periodically.
This calibration procedure requires the HI 8427
or the HI 931001 pH and ORP simulator to
simulate the ORP electrode.
HI 8427 or HI 931001 produce a known signal
into the system so that the faults of the
system can be isolated.
• Connect the ORP transmitter to the simu-
lator.
• Set the simulator to 0 mV and adjust the
offset trimmer to read 12 mA on the am-
meter or 0 mV on the HI 8615L display (HI
8615L only).

ORP CALIBRATION (HI8615 & HI8615L)
Initial preparation
Disconnect the +ve supply cable from the
"+VE LOOP" terminal and connect a 20 mA
f.s. ammeter between the +ve cable and the
"+VE LOOP" terminal. With HI 8615L the
instrument display can be used during cali-
bration without the need to connect the am-
meter. In this case the values are directly
expressed in mV units.
Pour a small quantity of HI7020
ORP solution into a beaker.
Procedure
• Connect the shorting BNC
connector to the ORP trans-
mitter.
• Adjust the OFFSET AD-
JUSTMENT trimmer on the module for a
display of 12 mA on the ammeter or 0 mV
on the instrument display (HI 8615L only).
This sets the zero point for the transmit-
ter.
• Connect the ORP electrode to the transmit-
ter and immerse the tip of the electrode
into a beaker of HI7020 ORP calibration
solution, and check that the ammeter read-
ing lies between 13.6 and 14.2 mA or the
instrument reading is between 200 and 275
mV at 25°C (HI8615L).

FOR HI8615L ONLY
The HI8615L is factory calibrated, and the
displayed values are referenced to the 4-20
mA loop current (e.g. LCD displays -1000
mV when loop current is 4.00 mA and dis-
plays +1000 mV when current is 20.00mA).
Under normal application, adjustment on this
module may not be necessary. If routine
check is required, the following procedures
shall be performed.
• Follow the above procedure for HI8615
(see page 12).
• Simulate a 12.00 mA loop current for the
transmitter (i.e. 0 mV at Electrode input)
and check display reading.
• Simulate a 20.00 mA loop current for the
transmitter (e.g. +1000 mV at Electrode
input) and check display reading.
• Set the simulator to 350 mV and adjust
the slope trimmer to read 14.8 mA on the
ammeter or 350 mV on the HI 8615L
display (HI 8615L only).
• Connect the ORP electrode to the module
and immerse the tip of the electrode into
the beaker of HI 7020 ORP solution and
check that the ammeter reading lies be-
tween 13.6 and 14.2 mA or the instrument
reading is between 200 and 275mV at
25°C (HI 8615L only).
• Only if the reading lies out-
side this range, adjust the
slope adjustment trimmer on
the transmitter to reflect a
reading within this range.

DO NOT BE ALARMED IF ANY SALT DE-
POSITS ARE PRESENT.
This is normal with electrodes and they will
disappear when rinsed with water.
During transport tiny bubbles of air may have
formed inside the glass bulb. The electrode
cannot function properly under these condi-
tions. These bubbles can be removed by

Note: when the meter is used in conjunction
with the Hanna indicator HI 8512T, or
the controller HI 8720T, the calibration
can also be performed on the indicator/
controller. In this case slight adjust-
ment can be made on the indicator/
controller even if the whole system cali-
bration is advised, always starting from
the transmitter.

PERIODIC MAINTENANCE
Inspect the electrode and the cable. The cable
used for connection to the meter must be
intact and there must be no points of broken
insulation on the cable or cracks on the elec-
trode stem or bulb. Connectors must be per-
fectly clean and dry. If any scratches or cracks
are present on the electrode body, replace
the electrode. Rinse off any salt deposits with
water.
For refillable electrodes
Refill it with fresh electrolyte (HI7071 for single
junction or HI7082 for double junction elec-
trodes). Allow the electrode to stand upright
for 1 hour.
Follow the Storage Procedure above.
CLEANING PROCEDURE
General Soak in Hanna HI7061 general
cleaning solution for approxi-
mately 1 hour.
Removal of films, dirt or deposits on the mem-
brane/junction:
Protein Soak in Hanna HI7073 protein
cleaning solution for 15 minutes.
Inorganic Soak in Hanna HI7074 inorganic
cleaning solution for 15 minutes.
Oil/grease Rinse with Hanna HI7077 Oil &
Fat cleaning solution.
IMPORTANT: After performing any of the
cleaning procedures rinse the electrode thor-
oughly with distilled water, drain and refill the
reference chamber with fresh electrolyte, (not
necessary for GEL filled electrodes) and soak
the electrode in HI70300 storage solution for
at least 1 hour before taking measurements.
"shaking down" the electrode as you would
do with a glass thermometer.
If the bulb and/or junction are dry, soak the
electrode in HI70300 storage solution for at
least one hour.
For refillable electrodes
If the fill solution (electrolyte) is more than
1cm (½") below the fill hole, add HI7082
3.5M KCl electrolyte solution for double junc-
tion or HI7071 3.5M KCl+AgCl electrolyte
solution for single junction electrodes. For a
faster response unscrew the fill hole screw
during measurements.
For AmpHel®electrodes
If the electrode does not respond to pH
changes, the battery is run down and the
electrode should be replaced.
MEASUREMENT
Rinse the electrode tip with distilled water.
Immerse the tip (4 cm / 1½") in the sample
and stir gently for approx. 30 seconds.
For a faster response and to avoid cross
contamination of the samples, rinse the elec-
trode tip with a few drops of the solution to be
tested, before taking measurements.
STORAGE
To minimize clogging and assuring a quick
response time, the glass bulb and the junc-
tion should be kept moist and not allowed to
dry out. Replace the solution in the protective
cap with a few drops of HI70300 storage
solution or, in its absence, filling solution
(HI7071 for single junction or HI7082 for
double junction electrodes). Follow the Prepa-
ration Procedure above before taking mea-
surements.
Note: NEVER STORE THE ELECTRODE IN
DISTILLED WATER OR DRY.

TEMPERATURE-RESISTANCE
CORRELATION FOR HANNA
pH SENSITIVE GLASS
The resistance of glass electrodes partially
depends on the temperature. The lower the
temperature, the higher the resistance. It takes
longer time for the reading to stabilize if the
resistance is higher. In addition, the response
time will suffer to a greater degree at tem-
peratures below 10°C.
Since the resistance of the pH electrode is in
the range of 200 Mohm, the current across
the membrane is in the pico Ampere range.
Large currents can disturb the calibration of
the electrode for many hours.
For these reasons high humidity environ-
ments, short circuits and static discharges
are detrimental for a stable pH reading.
The pH electrode's life also depends on the
temperature. If constantly used at high tem-
peratures, the electrode life is drastically re-
duced.
TROUBLESHOOTING
Evaluate your electrode performance based
on the following.
• Noise (Readings fluctuate up and down)
could be due to:
- Clogged/Dirty Junction: refer to the
Cleaning Procedure above.
- Loss of shielding due to low electrolyte
level (in refillable electrodes only): HI7071
for single junction or HI7082 for double
junction electrodes.
• Dry Membrane/Junction: soak in
HI70300 storage solution for at least one
hour.
• Drifting: soak the electrode tip in warm
Hanna solution HI7082 for one hour and
rinse the tip with distilled water. Refill with
fresh HI7071 for single junction electrodes
and HI7082 for double junction electrodes.
• Low Slope: refer to the Cleaning Proce-
dure above.
• No Slope: check the electrode for cracks
in glass stem or bulb and replace the
electrode.
• Slow Response/Excessive Drift: soak the
tip in Hanna HI7061 cleaning solution for
30 minutes, rinse thoroughly in distilled
water and then follow the Cleaning Proce-
dure above.

INSTALLATION PROCEDURE
AND EXAMPLES
The HI 8614, HI8614L, HI8615 and HI8615L
transmitters may be wall mounted in any con-
venient location near the measurement point.
To minimize thermal drift due to extreme tem-
peraturefluctuationsduringthemeasurement
process, particularly if the measurement is
conducted outdoors, it is best to protect the
transmitter in an enclosed casing.
General Installation Procedure
For most industrial application involving long
term monitoring and control, it is also recom-
mendedtousetankelectrodeholders(HI6050
orHI6051)toprotectthepHelectrodeandthe

High concentrations of sodium ions interfere
with readings in alkaline solutions; the pH at
which the interference starts to be significant
depends upon the composition of the glass.
This interference is the alkaline error and
causes the pH to be underestimated. Hanna's
glass formulations have the indicated charac-
teristics.
