These Mini Bayard Alpert Style and 8138/29D20 Triode style hot ionization gauge tubes measure a wide vacuum range. Smaller that standard glass Bayard-Alpert gauges, they are ideal for use in analytical instrumentation. Accidental exposure to atmosphere a normal operating temperatures will not damage the gauge because of the use of the thoria coated iridium filaments.
