Triode Style and Mini Bayard-Alpert Ion Gauge Tubes

HP Ion Gauge Tube
Triode style (342003)

These 8138/29D20 Triode style and Mini Bayard Alpert Style hot ionization gauge tubes measure a wide vacuum range. Smaller than 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.
