IGM402 Hornet hot cathode vacuum gauge with Yttria coated filaments. DN40KF flange

IGM402 Hornet is a modular miniature hot cathode Bayard-Alpert ionization vacuum gauge. The IGM402 can combine the vacuum measurements from the ionization gauge and one of the convection gauges to provide full range vacuum measurements, or simply operate the ionization gauge and the 2 convection gauges as individual gauges.

The operation of the gauge including degas, filament on/off and emission current is set by the front panel push buttons, digital inputs or RS485 commands.

For general vacuum applications, dual yttria coated filaments are offered for use with air and inert gases such as N2, argon, etc. Dual tungsten filaments are available for use with gases that may not be compatible with yttria coated filaments.
