MDC nude ionization gauge tubes are designed for high and ultrahigh
vacuum measurements between 1x10-3 to 2x10-11 Torr. Like their glass
enclosed counterparts, these are also hot cathode ionization types.
The main difference being their method of construction. Nude gauges
allow for easy replacement of perishable filaments and the added
durability of ceramic-to-metal electrical feedthrough insulation
which makes them bakeable to 450°C. Two nude gauge styles are
offered, these are resistive heating or electron bombardment degas.
