Wide Range Ionization Vacuum Gauge M-833HG

 
 
M-833HG is a control unit made exclusively for miniature B-A gauges. Optional expansion boards supporting versatile gauge and data output are available. The combination of miniature B-A gauge and TC gauge (option) and the use of auto filament that performs auto gauge switching enables highly accurate vacuum measurement from atmospheric pressure to ultra-high vacuum. Best suited for installation on high to ultra-high vacuum equipment.
Components
