Residual Gas Analysers

The perfect balance of high end performance and accessibility

Edwards RGA residual gas analysers

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

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 residual gas analyser

Edwards PRA RGAs deliver 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.

WRA wide range residual gas analyser

Edwards WRA RGAs are our 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.

This is paired with increased sensitivity compared to the PRA to allow for greater accuracy from your measurements.
