Maintenance
Heavy contamination of the sensor head may lead to false measured
values. Therefore, the sensor head must be checked for contamination
at regular intervals. If contaminations are visible, the sensor can be
cleaned as described below.
Cleaning the sensor tip
The sensor head can be cleaned to remove dust or dirt by moving it
carefully in warm water containing a dishwashing liquid or other allowed
cleaning liquid (e.g. isopropanol)

. Persistent incrustations or deposits
can be previously softened by prolonged immersion and then removed
by means of a soft brush or cloth. Avoid applying force to the sensitive
sensor tip.
The sensor head is a sensitive measuring system.
During manual cleaning proceed with great care.
Before putting it again into operation, wait until the sensor head is com-
pletely dry.
Sterilization
Both uncoated and coated sensors can be sterilized during operation.
Alcohols (drying without leaving residues) and hydrogen peroxide (un-
coated version only) are approved and certified disinfectants.
Spare parts or repair
No spare parts are available, since a repair is only possible at
SCHMIDT
Technology
. In case of defects, the sensors must be sent in to the sup-
plier for repair.
When the sensor is used in systems important for operation, we recom-
mend keeping a replacement sensor in stock.
Test certificates and material certificates
Every newly produced sensor is accompanied by a certificate of compli-
ance according to EN 10204-2.1. Material certificates are not available.
