pirani vacuum gauge GP-G series

GP-1000G is a constant-temperature Pirani vacuum gauge that works using the thermal conduction of gas. Digital output and set point output are provided standard, as vacuum system control features. To enable effective use of system panels, GP-1000G has been given a more compact design.


  • No re-calibration is needed after changing gauge head cable length.
  • Built-in temperature assurance circuit reduces effect of ambient temperature changes on specified values.
  • Independent set point output (3 points/GP-1000G, 2points/GP-2001G, GP-2002G)
  • BCD output (GP-1000G)
  • Wide range of power supply voltages (GP-1000G)
  • Conforms with CE


  • Pressure measurement for rough evacuation systems
  • Pressure monitors in evacuation systems
  • Process control for vacuum application devices
