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.

ACCESSORIES

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.
