Leak testing for OXYMAT 7

Procedure
1. Close the reference gas inlet.
2. Connect the sample gas outlet to a pressure measuring instrument.
3. Apply a pressure of approximately 3 000 hPa (absolute pressure) to the measuring inlet.
Then block the measuring inlet.
4. Wait for approximately 5 minutes until the sample gas that flowed in has reached the
ambient temperature and the pressure is stable. Note the pressure.
5. Wait an additional 5 minutes and note the pressure again.
If the pressure change is less than 10 hPa, the sample gas path is adequately tight.
