Vacuum gauge

Vacuum gauge Selection guide

Pressure measurement (vacuum measurement) is a fundamental technology that is essential for research and development, production technology, quality control, and manufacturing processes.

ULVAC is proud of its highly reliable vacuum gauges and vacuum measuring instruments that meet the needs in a wide range of fields.

A wide range of products from Pirani vacuum gauges to ultra-high vacuum measuring for various purposes of usages and other applications is available.

Transducer type vacuum gauge, space-saving and low cost, is also popular. JCSS Calibration Service We provide JCSS calibration service not only for ULVAC vacuum gauges but also for the vacuum gauges our customers currently have.
