Miniature Gauge MG-2/MG-2M/MG-2F MG-2/WF
A miniature gauge is a small gauge ball made of metal.
It enables pressure measurement from ultimate pressure to process pressure of sputters (measurement around 1Pa) with a single gauge.
Connects to gauge adapter (O-ring insertion type). (φ15mm, φ18mm)
NW16/25, φ34ICF, and φ70ICF type are available.
