BAG302 Medium to Ultra High Vacuum Gauge
The INFICON single Bayard-Alpert Hot Ion gauge BAG302 covers a wide measurement range from 1.3 × 10-9 to 6.7×10-2 mbar (1 × 10-9 to 5 × 10-2 Torr). The compact All-In-One Hot Ion gauge BAG302 offers an easy to exchange dual filament sensor, a built in OLED display, set-point relay and a log-linear analog output as well as an integrated RS485 digital interface for increased integration flexibility. These features combined with the rugged design makes the BAG302 an affordable and repeatable process to base pressure measurement instrument of its own and provides a high value/ low cost of ownership choice.
