VG502 vacuum gauge is a device used for vacuum measurements and it was conceived to be used for medium and low vacuum (104 ÷ 10-1 Pa) ranges and for pressure up to 160 bar. Specifically, the VG502 is an instrument that acquires and displays the signal coming from an external vacuum / pressure sensor (Pirani head, Active Pirani and strain gauge).

Compared with old generation vacuum gauges, the new VG502 includes:


  • Serial RS485 interface for host computer 
  • Wi-Fi communication
  • Automatic gas ballast option
  • Digital I/O for remote start/stop and indication of status of the unit
  • New back-lighted LCD display with alphanumeric and analogical display of measured value
  • Functional keyboard
  • IP54 protection level (only on the front panel)
