At Atmo-Seal, Inc., we know the life of an emissions probe is a dirty one. Our probes are made from the highest quality stainless steel, both inside and out.

We also offer probes designed with all Teflon wetted parts for the most corrosive conditions.

Mounting may be from a bolt on flange, sanitary flange, NPT or ISO threads. The mounting flange may be either fixed or adjustable, allowing for differing tunnel diameters and engagements.

Our heated probes carry a full 18 month limited warranty, too!
