Visiferm DO

The VisiFerm DO Arc is the first optical oxygen sensor with integrated opto-electronics, that has the full functionality of a measuring device with self-diagnostics. It can be steam sterilized, autoclavable and CIP compatible. The VisiFerm requires less maintenance than a classical oxygen sensor as it does not have a mechanically sensitive membrane or a corrosive electrolyte.
