Protection cap, measurement chamber, cooling coil 

If used in process conditions involving oil or dust, the protection cap 
and, if used, the measurement chamber and cooling coil must be 
cleaned regularly. 

•  

Unscrew/remove protection cap, measurement chamber and 
cooling coil and blow out with compressed air or place in an 
ultrasonic bath. 

• 

Replace a heavily soiled protection cap with the same type of 
protection cap. 

 

 

The accuracy is only maintained when the ordered 
protection cap is replaced by the same type of protection 
cap. 

 

Sensor cleaning 

 

 

During sensor cleaning, avoid any contact with the sensor. 

 

 

 

Do not mechanically clean the sensor, as otherwise the 
cover electrode may be damaged. 

 

1.

Carefully unscrew protection cap. 

2.

Carefully rinse with isopropanol and/or distilled water. 

3.

Allow sensor to dry thoroughly. 

4.

Screw on protection cap.
