Description
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.
Triode Style Mini-Ionization Gauge Tube
This new Triode Style Mini-Ionization Gauge Tube (342003) is designed to be a direct replacement for the Ion Gauge Tube utilized in the Agilent/HP and Thermo/Finnigan instruments mentioned below.
Agilent/HP Compatibility
The 342003 is compatible with the Agilent 5971/5972/5973/5975.
Thermo Compatibility
The 342003 is a direct replacement for Thermo #00105-01525, used on the Velos™, Exactive™, Orbitrap®, LTQ™ series, LCQ™ series, and LTQ FT™ series.
