Residual Gas Analysers

The perfect balance of high end performance and accessibility

Residual gas analysers

RGA residual gas analysers

Our RGA includes two variants: both come with simple and effective operation assuring high performance and efficiency 

All RGAs are equipped with dedicated, easy to use software which allows you to track your process in real-time from your laptop and do detailed analysis of up to 16 different units.

For those wanting a snapshot view, the units have a unique on-board display which can show you the main gas types as well as the overall pressure of your system without having to connect via a laptop.

PRA primary gas analyser

Delivering the perfect balance of high end performance and accessibility.

  • Available in four variants to suit your process needs, whether you just need a basic model or something with more sensitivity/range.
  • The PRA is the perfect starting point for analysing your processes.
Residual gas Analyser RGA

WRA wide range residual gas analyser

Top of the line models, with market leading specifications.

  • Available in two variants 1-200 or 1-300 amu, you can measure a wide range of gasses/by-products from your processes.
