AMS 5225

The oxygen analyser AMS 5225 is the right choice for applications to monitor the atmospheres of forming gas. It uses an electrochemical sensor.

To house the electrochemical sensors in its oxygen analysers, AMS has developed a series of measuring chambers which are gas-tight sealed. This guarantees leakage-free gas pathways, which is particularly important in Vol. % applications.
