Vacuum Gauge

Introduction Laboratory vacuum systems demand instruments that are precise, compact, easy to integrate, and cost-effective. Whether you are running surface-science experiments, operating an analytical mass spectrometer, performing thin-film deposition in a research coater, or calibrating vacuum standards, the right gauge selection directly affects data quality, experiment repeatability, and lab throughput. Over-specifying a gauge wastes budget; […]

Introduction Vacuum gauges are the eyes of any vacuum system. Selecting the wrong sensor can lead to inaccurate process control, extended pump-down times, or premature equipment failure. Two of the most widely used technologies—Pirani thermal conductivity gauges and cold cathode ionization gauges—cover the majority of industrial high-vacuum applications from 10−3 Torr down to 10−7 Torr.
