355 MICRO-ION® BAYARD-ALPERT VACUUM GAUGES
(5x10-10 to 5x10-2 Torr)
Bayard-Alpert style hot-cathode ionization vacuum gauges

MKS, Granville-Phillips® 355 Micro-Ion® Hot-cathode Bayard-Alpert Ionization Vacuum Gauges are the smallest Bayard-Alpert style gauges. They are more rugged and wider range than glass gauges. In addition, they generate less heat and provide greater burnout resistance.

355 Micro-Ion® Hot-cathode Bayard-Alpert Ionization Vacuum Gauges offer a host of advantages over glass gauges. At less than 5% of the volume of a glass gauge, it mounts in almost any location on your system. Its all-metal design eliminates costly downtime that can result from glass gauge breakage. The 355 Micro-Ion® Hot-cathode Bayard-Alpert Ionization Vacuum Gauge unique dual ion collectors and metal envelope provide measurement up to 5 x 10-2 Torr compared to approximately 5 x 10-3 Torr for a glass gauge. Plus, it has an x ray limit equivalent to that of a glass gauge (3 x 10-10 Torr).

355 Micro-Ion® Hot-cathode Bayard-Alpert Ionization Vacuum Gauges' 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 355 Micro-Ion® Hot-cathode Bayard-Alpert Ionization Vacuum 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.

FEATURES & BENEFITS:

• Small size that allows for easy installation in complex, tightly packed vacuum systems
• Rugged, all-metal design that eliminates costly downtime due to glass breakage
• Wider usable range compared to glass gauges
• Dual burn-out resistant filaments that provide long life for increased uptime
• Lower power requirements that result in less heat generation
