Vacuum technology — Vacuum gauges — Characteristics for a stable ionisation vacuum gauge
This document describes a special design of an ionisation vacuum gauge which has a well-defined ionising electron path length.[2] Due to the construction design, it leads to good measurement accuracy, long-term stability, as well as gauge independent and reproducible sensitivity for nitrogen and relative sensitivity factors[3][4]. It is designed for the measurement range of 10-6 Pa to 10-2 Pa.…
