Inficon Thin-Film Thickness Deposition Rate Monitor Crystal Holder Feedthrough

Inficon Thin-Film Thickness Deposition Rate Monitor Crystal Holder Feedthrough for High Vacuum Chamber.

Main flange is 2.75" DN35CF-DN40CF High Vacuum Flange. Knife Edge is in perfect condition.

Has water cooling lines. Will need a new swagelok fitting on one side. BNC connection connects up to the crystal holder. Measures about 12" from flange to xtal holder. Has some deposition on the metal tubes, still works well. See photos.
