      The XT residual gas analyzer (RGA) from Extorr offers exceptional performance and value.
      
                        
      These RGAs provide a more detailed vacuum gas analysis than is offered by any other single
      
                        
      competitive device. Each system comes complete with a multi-gauged quadrupole probe, a
      
                        
      control and communications unit (CCU), and a real-time Windows? software package.
