HI769828 is the multisensor probe for
HI9828.
The probe has been designed to resist to all
harsh operating conditions. It is very easy-to-
use and can be installed for direct pipe
measurements.
The protection sleeve allows to dip the probe
for a long period without damag-ing the sensors
and the calibration beaker permits to perform
maintenance opera-tions directly on field.
Calibration data are stored in the probe internal
memory, so that sensors can be changed
without needing recalibration. The user can
disconnect all sensors sepa-rately for a better
cleaning and to change the probe body, if for
example a different cable length is required.

INSTALLATION
D.O. sensor
The temperature sensor built near
the galvanic D.O. sen-sor allows
stable temperature compensated
D.O. readings in a few seconds.
The thin permeable membrane isolates the sensor
elements from the testing solu-tion, but allows oxygen
to enter. Oxygen that passes through the membrane
causes a current flow, from which the oxygen
concentration is determined.
The D.O. sensor is shipped dry. Activate it before
installing the probe. To hydrate the sensor and
prepare it for use proceed as follows:
• Remove the black & red plastic cap. This cap is used
for shipping purposes only and can be thrown
away.
•Insert the O-ring in the membrane.
•Rinse the membrane with HI7042S electrolyte
solution while shaking it gently. Refill with clean
electrolyte. Gen-tly tap the membrane over a
surface to ensure that no air bubbles remain
trapped. To avoid damaging the mem-brane, do
not touch it with your fingers.
•With the sensor facing down screw the cap
clockwise to the end of the threads. Some electrolyte
will overflow.
•Insert the sensor in the probe body with the right
alignment to the corresponding white connector.
•With the supplied tool screw the locking nut to fix
the sensor.
Conductivity sensor
The conductivity sensor uses the 4-
ring technology that allows stable
and linear readings without any
inter-ference in the whole range.
• Insert the sensor in the probe body with the right
alignment to the corresponding blue connector.
• With the supplied tool screw the locking nut to fix
the sensor.
pH and pH/ORP sensor
The pH and pH/ORP sen-sors are
gel filled and fea-ture cloth
junction, glass and Pt sensors
respectively. The external plastic
body is built to last even in harsh
environmental conditions.
• Insert the sensor in the probe body with the right
alignment to the corresponding red connector.
• After mounting the sensors, screw the protection
sleeve for taking measure-ments or the
transparent beaker for performing calibration.
• With the meter off, connect the probe to the DIN
socket on the bottom of the meter by aligning the
pins and pushing in the plug. Tighten the nut to
ensure a good connection.

PROBE MAINTENANCE
General maintenance
After use, rinse the probe with tap water
and dry it. The pH electrode bulb must be
kept moist, while the D.O. and EC sensors
should be stored dry.
Maintenance of D.O. sensor
For a top performance probe, replace
the membrane every 2 months and the
electrolyte once a month. Proceed as
follows:
• Unscrew the membrane by
turning itcounterclockwise.
• Rinse the spare membrane
with some electrolyte while
shaking it gently. Refill with
clean electrolyte.
•Gently tap the membrane over a surface to
ensure that no air bubbles remain
trapped.
• With the sensor facing down, screw the
cap clockwise to the end of the threads.
Some electrolyte will overflow.
If any deposit scales the sensors, gently brush
the sensor surface with the brush supplied in
the maintenance kit, while paying attention
to not damage the plastic body.
Maintenance of EC sensor
After every series of measurements, rinse
the probe with tap water.
If a more thorough cleaning is required,
clean the probe with the brush supplied
in the maintenance kit or a nonabrasive
detergent.
After cleaning the probe, always re-
calibrate the instrument.
Maintenance of pH & pH/ORP sensors
• 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.
• Shake the electrode down as you would
do with a clinical thermometer to elimi-
nate any air bubbles inside the glass
bulb.
• If the bulb and/or junction are dry, soak
the electrode in HI70300 storage solu-
tion for at least one hour.
• To minimize clogging and ensure a quick
response time, the glass bulb and the
junction should be kept moist and not
allowed to dry.
• Replace the solution in the protective cap
with a few drops of HI70300 storage
solution. Tap water may also be used
for a very short period (couple of days).
NEVER STORE THE ELECTRODE
IN DISTILLED OR DEIONIZED
WATER.
• Inspect the electrode for scratches or
cracks. If any present, replace the elec-
trode.
• Cleaning procedure: clean frequently
the probe by soaking it for 1 minute in
HI70670 or HI70671 cleaning solu-
tions. After performing this procedure,
soak the electrode in HI70300 storage
solution before taking measurements.
NOTE For additional information about
calibration, connections and
readings, please refer to the instru-
ment (HI9828 multiparameter)
instruction manual.
