The MBA2-200 hot filament gauge is the smallest Bayard-Alpert ionization gauge (less than 5% of the volume of a glass gauge). This gauge’s all-metal design eliminates the possibility of breakage. It generates low heat, provides good burnout resistance, and mounts in almost any location on your system.
The MBA2-200’s unique dual ion collectors and metal envelope provide measurement up to 5 x 10-2 Torr and it has an X-ray limit equivalent to that of a glass gauge (3 x 10-10 Torr). Dual, burn-out resistant, yttria-coated iridium filaments provide long life. As a result, you can avoid unscheduled downtime by using the second filament as a backup until the gauge can be replaced during regular maintenance procedures. In addition, the MBA2-200 ionization gauge requires only 8% of the power of a glass gauge, which means less heat to potentially disturb a process or experiment, cause accidental burns, or melt wiring that may come in contact with the gauge.
