GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
HI 8614/HI 8614L (pH) and HI 8615/HI 8615L (ORP) are 2-wire
water-resistant transmitters specially designed for long distance
measurement of pH or ORP in industrial applications.
HI 8614 and HI 8615
and HI 8615L are models with LCD.
The LCD allows easy verification and monitoring 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.
HI 8614 and HI 8614L, can be connected to the Hanna process
instruments HI 8510, HI 8710, HI 8711 or to any recorder,
computer or data monitor that accepts 4 to 20 mA input.
HI 8615 and HI 8615L, can be connected to the Hanna process
instruments HI 8512, HI 8720 or to any recorder, computer or data
monitor that accepts 4 to 20 mA input.
The transmitters use a universal BNC socket for quick and secure
connection to any electrode with a BNC connector.

performed by the transmitter's ATC circuitry if the temperature probe
(HI 76608, optional) is attached. If ATC is not required, it is possible
to substitute the temperature 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
connections, 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 HI 8614
family models only).
The unit is enclosed in a protective casing conforming to IP 65
standards.

Unscrew the 4 screws and remove the top cover.
There are three cable glands on the transmitter cover. The large cable gland
with the split in the rubber is for the electrode.
Connect the positive supply to the strip terminal "+VE LOOP" and the
negative supply to the terminal "-VE LOOP" of the transmitter terminal
block.

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 distance 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.
Electrode connection: connect the BNC
of the cable to the BNC socket on the
transmitter.

Pour small quantities of pH7.01 and pH4.01 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. In
this way contamination of the buffers is minimized.
To get accurate readings, use pH7.01 and pH4.01 if you are going
to measure acid samples or pH 7.01 and pH 10.01 for alkaline
measurements.
Note: With HI 8614L the instruments
display can be used during
calibration without the need to
connect the ammeter and the
reading is directly expressed in
pH units.
A 2 kohm resistor is factory mounted for 25°C temperature compensation.
89
PROCEDURE
• Disconnect the +ve supply cable from "+VE LOOP" terminal and
connect a 20mA f.s. ammeter between the +ve cable and "+VE
LOOP" terminal.
• Adjust the slope trimmer until the ammeter reads 8.58 mA for
HI 8614
and HI 8614L or the display shows "4.01" at 25°C. For
other buffer temperatures, refer to page 12 for the appropriate
mA / pH reading.
If you are using pH 10.01 buffer
solution adjust the slope trimmer
until the ammeter read 15.43 mA at
25°C (77°F) or the value indicated at
page 12.
• Remove the protective cap from the electrode,
rinse it with some pH 7.01 solution or immerse it
in the pH 7 rinse solution, then immerse the pH
electrode and temperature probe into pH7.01
calibration buffer solution; shake briefly and wait
for the reading to stabilize.
Note: The tip of the electrode should be
submerged approximately 4 cm (1½")
into the solution. The temperature probe
should be located as close to the pH
electrode as possible.
• Adjust the offset trimmer until the ammeter reads 12 mA or the
display shows "7.01" if the temperature of the buffer is at 25°C.
For other buffer temperatures, refer
to page 12 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 pH 4 rinse
solution (2nd calibration point). Dip the electrode
and the temperature probe into pH 4.01 (or
10.01) calibration buffer solution, shake briefly
and wait for a few minutes for reading to stabilize.
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 the loop current is 4.00 mA and displays 14.00 pH
when the current is 20.00 mA).
Under normal application, adjustment on this module may not be
necessary.
If routine check is required, the following procedures shall be performed.
• Follow the procedure at page 10 to perform calibration on the
transmitter module (using a ammeter).
• Simulate a 4.00 mA loop current for the transmitter (i.e. 0.00 pH
as Electrode input) and check for display reading.
• Simulate a 20.00 mA loop current for the transmitter (i.e.
14.00 pH as Electrode input) and check for display reading.
Note:When HI 8614 or HI 8614L instruments are used in
conjunction with the new Hanna indicator HI 8510 or
controllers HI 8710 and HI 8711, the calibration can also
be performed on the indicator/controller. In this case slight
calibration adjustment can be made on the indicator/
controller even if the whole system calibration is advised,
always starting from the transmitter.

pH CALIBRATION WITH FIXED TEMPERATURE
pH CALIBRATION WITH FIXED TEMPERATUREpH CALIBRATION WITH FIXED TEMPERATURE
• Take the temperature of the buffer
solutions using a Checktemp or a
thermometer with a resolution of at
least 1°.
• Connect the appropriate resistor
to the "TEMP. PROBE" terminals
(see page 8) depending on the
temperature of the calibration solution.
• Follow the procedure as outlined in the calibration with automatic
temperature compensation and use the thermometer reading to
adjust the trimmer until the ammeter reads the value according
to the following table.
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 calibration without the need to connect the ammeter.
In this case the values are directly expressed in mV units.
Pour a small quantity of HI 7020 ORP solution
into a beaker.
PROCEDURE
• Connect the shorting BNC connector
to the ORP transmitter.
• Adjust the OFFSET ADJUSTMENT
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 transmitter.
1213
• Connect the ORP electrode to
the transmitter and immerse
the tip of the electrode into
a beaker of HI 7020 ORP
calibration solution, and check
that the ammeter reading lies
between 13.6 and 14.2 mA
for HI 8615 or the instrument
reading is between 200 and
275 mV at 25°C (HI 8615L).
• 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
module 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 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 between 13.6 and 14.2 mA for
HI 8615,
or the instrument reading is between 200 and 275mV
at 25°C (HI 8615L only).
• Connect the ORP transmitter to the simulator.
• Set the simulator to 0 mV and adjust the offset trimmer to read
12 mA on the ammeter or 0 mV on the HI 8615L display.
• Set the simulator to 350 mV and adjust the slope trimmer to
read 14.8 mA for HI 8615 on the ammeter or 350 mV on the
HI 8615L
display.
• Only if the reading lies outside this
range, adjust the slope adjustment
trimmer on the transmitter to reflect
a reading within this range.
FOR HI8615L ONLY
The HI 8615L are factory calibrated, and the displayed values are
referenced to the 4-20 mA loop current. 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 HI 8615
• 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 for HI 8615L at Electrode input) and check display
reading.

PREPARATION PROCEDURE
Remove the protective cap.
DO NOT BE ALARMED IF ANY SALT DEPOSITS 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 conditions.
These bubbles can be removed by "shaking down" the electrode as
you would do with a glass thermometer.
If the bulb and/or junction are dry, soak the electrode in HI 70300
storage solution for at least one hour.

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 electrode 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 junction should be kept moist and not allowed to dry
out. Replace the solution in the protective cap with a few drops of
HI 70300
storage solution or, in its absence, filling solution (HI 7071
for single junction or HI 7082 for double junction electrodes). Follow
the Preparation Procedure above before taking measurements.
Note: NEVER STORE THE ELECTRODE IN DISTILLED WATER OR DRY.
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 electrode stem or bulb.
Connectors must be perfectly 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 electrodesFor refillable electrodes

For refillable electrodesFor refillable electrodes
Refill it with fresh electrolyte (HI 7071
for single junction or HI 7082
for double junction electrodes). Allow the electrode to stand upright for
1 hour.
Follow the Storage Procedure above.
CLEANING PROCEDURE
• GeneralSoak in Hanna HI 7061
general cleaning solution
for approximately 1 hour.
Removal of films, dirt or deposits on the membrane/junction:
• ProteinSoak in Hanna HI 7073 protein cleaning solution
for 15 minutes.
• InorganicSoak in Hanna HI 7074 inorganic cleaning solution
for 15 minutes.
• Oil/greaseRinse with Hanna HI 7077 Oil & Fat cleaning
solution.
IMPORTANT: After performing any of the cleaning procedures rinse
the electrode thoroughly 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.
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): HI 7071 for single junction or HI 7082 for
double junction electrodes.
••
• Dry Membrane/Junction: soak in HI 70300 storage solution for
••
at least one hour.
••
• Drifting: soak the electrode tip in warm Hanna solution HI 7082
••
for one hour and rinse the tip with distilled water. Refill with fresh
HI 7071 for single junction electrodes and HI 7082 for double
junction electrodes.
••
• Low Slope: refer to the Cleaning Procedure 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 HI 7061
cleaning solution for 30 minutes, rinse thoroughly in distilled
water and then follow the Cleaning Procedure above.
The resistance of glass electrodes partially depends on the temperature.
The lower the temperature, the higher the resistance. It takes more
time for the reading to stabilize if the resistance is higher. In
addition, the response time will suffer to a greater degree at
temperatures below 25 °C (77 °F).
Since the resistance of the pH electrode is in the range of 50-200
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 environments, 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 temperatures, the electrode life is drastically reduced.

Alkaline Error
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 called
alkaline error and causes the pH to be underestimated. Hanna's glass
formulations have the indicated characteristics.

INSTALLATION PROCEDURE AND EXAMPLESINSTALLATION PROCEDURE AND EXAMPLES
The HI 8614 family and HI 8615 family transmitters may be wall mounted
in any convenient location near the measurement point. To minimize
thermal drift due to extreme temperature fluctuations during the
measurement 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 recommended to use tank electrode holders (HI6050 or
HI6051) to protect the pH electrode and the temperature probe from
contamination by the test solution.
