PRELIMINARY EXAMINATION

Remove the instrument from the packing
material and examine it carefully to make
sure that no damage has occurred during
shipping. If there is any noticeable damage,
notify your Dealer.

Note: Save all packing material until you

are sure that the instrument functions
correctly. All defective items must be
returned in the original packing mate­rial together with the supplied acces­sories.

GENERAL DESCRIPTION

HI 8614 - HI 8614L (pH) and HI 8615 ­HI 8615L (ORP) are 2-wire water-resistant

transmitters designed specially for long dis­tance measurement of pH or ORP for use in
industrial applications.

Two versions are available: the standard
HI8614 or HI8615 and HI8614L or HI8615L
with an LCD.

The LCD versions allow easy verification
and monitoring of measured values and are
easier to calibrate and maintain.

The pH or ORP signal is transmitted in a 2­wire current loop in the range of 4 to 20 mA.

HI8614 and HI8614L can be connected to
Hanna process instruments HI 8510T,
HI8710T or HI 8711T, recorders, computers
or any data monitoring device that accepts
4 to 20 mA input.

HI8615 and HI8615L can be connected to
Hanna meters HI8512T, HI8720T or any
recorders, computers or data monitor that
accepts 4 to 20 mA input.

3

The transmitters use a universal BNC socket
for quick and secure connection to any elec­trode with a BNC connector.

For HI8614 - HI8614L: temperature com­pensation is performed by the transmitter's
ATC circuitry when measurements are taken
with the temperature probe attached
(HI76608, optional); it is also possible to
substitute the temperature probe with a fixed
resistor if ATC is not required.

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 100V ensures true differential read­ings.

A terminal board in the transmitter provides
for connection of power supply, pH or ORP
electrodes (and temperature probe for
HI8614 & HI 8614L).

The unit is enclosed in a protective casing
conforming to IP65 standards.

TERMINAL BOARD CONNECTIONS

Remove the 4 screws and take the top cover
off.

There are three cable glands on the cover of
the transmitter: two smaller ones and a large
one. The large cable gland with the split in the
rubber is for the electrode.

ELECTRODE

CABLE GLAND

WIRE CABLE GLANDS

Connect the positive supply to the strip termi­nal "+VE LOOP" and the negative supply to
the terminal "-VE LOOP" of the transmitter
terminal block.

7

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.

For HI 8614 & HI 8614L only:
for automatic temperature
compensation, connect the 2
terminals of the temperature
probe (HI76608, optional) to
"TEMP. PROBE" terminals.
If automatic temperature com­pensation is not required, short
the "TEMP. PROBE" terminals
with a resistance according to
the external temperature:

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
pH 4.01 if you are going to measure acid
samples or pH 7.01 and pH 10.01 for alka­line measurements.

used during calibration
without the need to con­nect the ammeter and the
reading is directly ex­pressed in pH units.

CALIBRATION

HI 7007

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.

• 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

HI 7007

temperature 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 sub­merged approxi­mately 4 cm (1½")
into the solution. The

4 cm

1½"

temperature probe
should be located as
close to the pH elec­trode as possible.

• Adjust the offset trimmer until the am-

meter reads 12mA or the display shows
"7.01" (HI 8614L only) if the temperature
of the buffer is at 25°C.

For other buffer temperatures, refer to
page 11 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 tempera-

HI 7004

ture probe into pH 4.01 (or

10.01) calibration buffer so­lution, shake briefly and
wait for a few minutes for
reading to stabilize.

• Adjust the slope trimmer until the amme-

ter reads 8.58 mA or the display shows
"4.01" at 25°C. For other buffer tempera­tures, refer to page 11 for the appropri­ate mA / pH reading (HI 8614L).

If you are using pH 10.01
buffer solution adjust the
slope trimmer until the am-

mA

meter read 15.43mA at
25°C (77°F) or the value
indicated at page 11.

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).

11

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 7 to per-

form calibration on the transmitter mod­ule (using a ammeter).

• Simulate a 4.00 mA loop current for the

transmitter (i.e. pH 0.00 as Electrode in­put) 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 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 COMPENSATION

(HI 8614 & HI 8614L only)

• Take the temperature of the

°C

buffer solutions using a
Checktemp or a thermom­eter 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 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.

ORP CALIBRATION (HI8615 & HI8615L)

mA

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 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

HI7020 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.

SLOPE ADJUSTMENT
OFFSET ADJUSTMENT

• 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 or the instrument reading is be­tween 200 and 275 mV at 25°C (HI8615L).

HI 7020

• If the reading lies outside

mA

this range, adjust the slope
adjustment trimmer on the

SLOPE ADJUSTMENT

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 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 (HI 8615L only).

SLOPE ADJUSTMENT
OFFSET ADJUSTMENT

15

• 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).

SLOPE ADJUSTMENT

mA

• 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 or the instru­ment reading is between 200 and 275mV
at 25°C (HI 8615L only).

HI 7020

mA

• Only if the reading lies out­side this range, adjust the
slope adjustment trimmer
on the transmitter to reflect

SLOPE ADJUSTMENT
OFFSET ADJUSTMENT

a reading within this range.

16

FOR HI8615L ONLY:

The HI 8615L 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 dis­plays +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 HI 8615
(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.

17

Please note:

-1000 mV = 4 mA
0 mV = 12 mA

1000 mV = 20 mA

350 mV = 14.8 mA
200 mV = 13.6 mA
275 mV = 14.2 mA

1 mV = 12.008 mA

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
adjustment can be made on the indi­cator/controller even if the whole sys­tem calibration is advised, always start­ing from the transmitter.

PREPARATION

Remove the protective cap.
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 condi­tions. These bubbles can be removed by
"shaking down" the electrode as you would

19

do with a glass thermometer.
If the bulb and/or junction are dry, soak the

electrode in HI70300 or HI80300 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 HI 7082 or
HI 8082 3,5M KCl Electrolyte Solution for
double junction or HI 7071 or HI 8071 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 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 HI70300 or
HI80300 Storage Solution or, in its ab­sence, Filling Solution (HI 7071 or HI 8071
for single junction or HI 7082 or HI 8082 for
double junction electrodes). Follow the Prepa­ration Procedure above before taking mea­surements.

Note: NEVER STORE THE ELECTRODE

IN DISTILLED WATER OR DRY.

20

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 electrodes:

Refill it with fresh electrolyte (HI7071 or
HI8071 for single junction or HI7082 or
HI8082 for double junction electrodes). Al-

low the electrode to stand upright for 1 hour.
Follow the Storage Procedure above.

CLEANING PROCEDURE

General Soak in Hanna HI7061 or

HI 8061 General Cleaning So­lution for approximately 1 hour.

Removal of films, dirt or deposits on the
membrane/junction:

Protein Soak in Hanna HI7073 or

HI8073 Protein Cleaning So­lution for 15 minutes.

Inorganic Soak in Hanna HI7074 or

HI8074 Inorganic Cleaning
Solution for 15 minutes.

Oil/grease Rinse with Hanna HI7077 or

HI 8077 Oil and 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 or
HI80300 Storage Solution for at least 1
hour before taking measurements.

21

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 electro-

lyte level (in refillable electrodes only):

HI7071 or HI8071 for single junction or
HI7082 or HI8082 for double junction

electrodes.

• Dry Membrane/Junction: Soak in Stor­age Solution HI70300 or HI80300 for at

least 1 hour.

• Drifting: Soak the electrode tip in warm
Hanna Solution HI7082 or HI8082 for
one hour and rinse the tip with distilled
water. Refill with fresh HI7071 or HI8071
for single junction electrodes and HI7082

or HI8082 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 Solution HI7061 or
HI8061 for 30 minutes, rinse thoroughly
in distilled water and then follow the
Cleaning Procedure above.

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 temperatures 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 tem­peratures, the electrode life is drastically
reduced.

23

Typical Electrode Life
Ambient Temperature 1- 3 years

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 characteristics.

INSTALLATION PROCEDURE

AND EXAMPLES

The HI8614, HI8614L, HI8615 and HI 8615L
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.
