Information concerning the compliant handling of O2
Improper handling of gas mixtures with an oxygen content of
more than 21 % or pure oxygen can lead to fires or explosions.
It is explicitly pointed out that the customer, when opening the
packaging, assumes full responsibility for cleanliness of sensor
and its accessories according to standard IEC/TR 60877:1999.
As a general rule, it is essential to avoid contamination of those parts of
the sensor that come into contact with oxygen:
- Carefully clean the installation site before mounting the sensor.
- Make sure to use only clean tools and material for installation.
- Before opening the packaging film, remove any dirt such as dust from
its surface, if necessary.
- If possible, wait until you are at the installation site before opening the
packaging to take out the sensor.
- Otherwise open the packaging film at an appropriate and clean work-
place and store the sensor in an appropriate, cleaned, dust- and hu-
midity-tight container.
- Do not touch the oxygen contacting sensor parts with bare hands.
- Use clean, non-fluffy gloves or cloths or similar to handle the sensor.
