Test criterion

The sensor is OK if < 2 % oxygen saturation is displayed as the 
measured value.

If the measured value is > 2 %:

Clean the gold working electrode (see section 5.4.1 C

LEANING

 

THE

 

GOLD

 

WORKING

 

ELECTRODE

) and change the electrolyte and 

membrane cap (see section 5.3 C

HANGING

 

THE

 

ELECTROLYTE

 

AND

 

MEMBRANE

 

CAP

).

If necessary, also clean the silver counter electrode (see section 
5.4.2 C

LEANING

 

THE

 

SILVER

 

COUNTER

 

ELECTRODE

).

5.6

Storage

Store the clean and dry sensor with its protective cap in place. 
Observe the allowed temperature range (see chapter 7 T

ECHNICAL

 

DATA

). The sensor may be stored in any position.

5.7

Disposal

We recommend to dispose of the sensor without the membrane cap as 
electronic refuse.

CAUTION

The ELY/A electrolyte solution irritates eyes, skin and mucus 
membranes. If it comes into contact with the eyes, rinse 
thoroughly with water and consult a doctor! During working 
activities, always wear suitable protective gloves and protective 
goggles/face shield! Follow the safety datasheet.

Disposal of the

membrane cap

#

1

Before disposing of the membrane cap, unscrew it and rinse 
with water.

2

Dispose of the membrane cap in the household refuse.

To dispose of the chemicals, follow the corresponding 
safety datasheets. The safety datasheets can be obtained 
from WTW.
