IGM400 Hornet hot cathode vacuum gauge with Yttria coated filament. DN16KF flange

The IGM400 Hornet is a hot cathode Bayard-Alpert ionization vacuum gauge module designed to work specifically with B-RAX 3200 vacuum gauge controller. They feature a dual hot filament yttria coated iridium or optional tungsten, and a robust, compact, all-metal construction.

The IGM400 Hornet allows for remote operation, with features like auto-zeroing of the electrometer circuit for temperature drift prevention, automatic emission current adjustment, and a field-replaceable gauge sensor assembly, ensuring optimal and stable pressure readings across the entire measurement range.
