2.2.IGE-3000 Mini Bayard/Alpert (B/A) Tube
The
stainless steel. It is UHV compatible and utilizes a fine wire collector located in the center of the grid. The duel Yttria coated filaments are individually supported to provide uniform output over variations in temperature and normal ageing. The typical user should experience a filament lifetime of approximately 10,000 hours. Its physical size is much smaller than the traditional glass type B/A tube. Since there is no glass envelope, the traditional safety concerns associated with glass type B/A tubes is eliminated.

*Accuracy specification is with the B/A tube originally shipped with the IGE 3000. The IGE 3000 is calibrated with and matched to the B/A tube at the factory. Changing or swapping the B/A tube with a B/A tube one other than the one originally shipped with the unit may effect the calibration.
**Complies with IEC
