Replacement Ion (Hot Filament) Gauge Tubes

Lesker Replacement Ion (Hot Filament) Gauge Tubes

The Kurt J. Lesker Bayard-Alpert ion gauges have a reasonably linear response from 1 x 10^-4 Torr to 1 x 10^-9 Torr, with gauge sensitivities from 5 to 20 Torr^-1. B-A gauges are available with one or two filaments (the second acting as a spare) and with two filament materials thoria-coated iridium, used in oxygen-rich applications and for “burn-out” protection if accidentally vented and tungsten, used for lower cost and in residual gases containing halogens.
