 Frequently Ask Questions 

1. Will this sensor fit my machine?

Search the part number printed on your old cell, or browse by manufacturer. There are 329 cross-references across 90 manufacturers. If the label has worn off, send us a photo and we will tell you.

2. How long does a medical oxygen sensor last?

Expected life is 1,000,000 Vol.%·h. How long that takes depends on the oxygen concentration and the temperature the cell runs at. A cell in a ventilator running high FiO₂ reaches it sooner than one in an oxygen analyser.

3. How do I know when my oxygen sensor needs replacing?

The usual signs are a reading that drifts, a cell that will not hold calibration, and a cell that cannot reach full scale during a calibration check.

4. Is a compatible sensor as safe as the original?

Our cells are tested to DIN EN ISO 80601-2-55, the same standard your equipment is tested against. They are CE marked, ISO certified and FDA registered.

5. Can I get certificates and declarations of conformity?

Yes, if you're a distributor or organization requiring proof of compliance, we can provide certification documents and test reports upon request.

5. Do you ship internationally?

Yes. We ship worldwide from our warehouse in Germany. Express and tracked delivery options are available.
