307 Bayard-Alpert Vacuum Gauge Controller
Model: 307501-000-M3
Overview
Overview
The 307501-000-M3 Vacuum Gauge Controller is configured for Series 274 glass tubulated or nude (not UHV) Bayard-Alpert gauges with resistive degas and comes with a half rack mount and remote power supply. It displays mBar measurement units, and is powered by 220 VAC with an EU power cord. Series 307 controllers measure pressure, and utilizes pressure related outputs to control a variety of vacuum system functions and processes.
