In typical medical applications, such as respiratory or cpap in homecare use, due to the oxygen consumption, electrochemical sensors commonly suffer on lifetime at high oxygen exposition over time. In addition, high gas flow rates and, in some cases, the presence of CO₂, are cutting down lifetime.

Over the past years our lead-free sensors do have only little noticeable signs of wear and tear as described above.

itg shows so much trust in the new technology that it warrants their lead-free sensors with up to 4 years of operation.
