Display Unit Pirani Gauge ISG-1 Series

This single channel vacuum gauge display is compatible with all G-TRAN series and CCM series sensors. Enables users to view system status at a glance.


  • Compatible with all G-Tran series, and capacitance manometer CCM series
  • Control output signal:3 set- point output
  • Operates in DC 24V power input (100V AC to 240V AC optional AC adapter)
  • Output signal:Linear 0 to10V
  • Serial communication type:RS485 communication is standard
  • High visibility LED
  • Compatible with DIN standards (compact in size of 48 X 96 mm)
  • CE compliant 


  • Vacuum systems (photovoltaic feld, FPD, semiconductor and optics)
  • Systems which require many set points
