Residual Gas Analysers (RGA) for Vacuum Applications

The new range of eVision2 residual gas analysers with web-enabled technology deliver unrivalled data acquisition speed and quality not possible with previous design residual gas analysers. Patented technology ensures millisecond data point collection even over the full dynamic measurement range and without any loss of data quality. Perfect for rapid leak detection, accurate vacuum diagnostics, chamber diagnostics and contamination monitoring, eVision2 residual gas analysers provide all the answers...fast.


Residual Gas Analysers - Latest Smart Head Technology:

  • Integrated web server, operate your residual gas analyser and review data from anywhere in the world, or just from your desk.eVision2 Residual Gas Analyser (RGA)
  • 100 or 200 amu mass range options.
  • Multiple modes of operation including vacuum survey, leak detect, bar graph etc.
  • Operation over any TCP/IP network, including the internet.

Residual Gas Analysers with Clear Technology Leadership:

  • Intelligent acquisition that skips larger peaks if requested to do so in order to increase electron multiplier lifetime (download application note here).
  • Fastest data acquisition over largest dynamic range of any commercial residual gas analyser. Perfect for closed-loop control applications and fast event studies.
