This is the ideal
mounting position
The solution flow should be directed
into the end of the sensor and
allowed to pass out of the
circulation holes of the outer
electrode.
The sensor should be mounted so
the cavity does not trap air or solids.

Vertical mounting is possible, if the
pipe is full and bubbles do not
accumulate near the electrodes.
Horizontal branch mounting is
usually a better alternative. The
solution must circulate past the
electrodes for accurate
measurements.

Mount the sensor in a vertical pipe
with the flow direction up. Mettler-
Toledo Thornton, Inc. does not
recommend mounting the sensor in
a vertical pipe with the flow
direction down, because air bubbles
or air pockets will affect the sensor
measurement.

Sensor Maintenance
Note: Contaminated sensors can give inaccurate high or low readings, depending upon the type
and location of contaminant accumulation. Both the electrodes and the insulating surfaces
must be cleaned to ensure accurate readings.
If contamination is suspected, removed the sensor from its fitting and clean the electrodes and
insulator. When cleaning, use a cotton swab saturated with a mild detergent or a very diluted
(0.5% or less) inorganic acid, i.e. HCl (Hydrochloric Acid), H
2
SO
4
(Sulfuric Acid), HNO
3
(Nitric Acid). If cleaning with acid use standard acid handling safety procedures.
Rinse thoroughly with distilled or deoinized water before installation. Avoid touching the
cleaned surfaces because oil from your hands will recontaminate the sensorl.
DO NOT USE ABRASIVE MATERIALS such as steel wool or nylon scrubbers, these
may harm the electrode surface and could affect the accuracy.
