Can this unit be used with Oxygen? If not does omega offer one for use with oxygen?
The wetted parts of this switch are all stainless steel so they can be used for oxygen once they have been cleaned for oxygen service. We do not offer oxygen cleaning. You would be required to have these cleaned by an independent service.
