PVG-500S Pirani Gauge Vacuum Measurement Agilent Technologies

The Agilent PVG-500 / 500S(tungsten) / 502S(nickel) series of Pirani gauges provides the ultimate combination of state-of-art technology and ruggedness within a compact design. The PVG-500 series utilizes the most advanced digital Pirani technology combined with a stainless steel sensor design to meet the various needs of the market today.

  • Simplified integration with a compact, rugged aluminum housing that mounts in any orientation with a logarithmic signal output
  • Stainless steel sensor cell with metal-sealed feedthrough provides a rugged design for a wide range of applications
  • Set-up is easy with push button ATM and High Vacuum (HV) adjustment
  • Nickel filament option for applications in corrosive environments
  • Optional set points allowing for the utilization of pressure readings to perform critical operations
