SRS RGA200 Gas Analyzer

$2,500

The 200 amu residual gas analyzers from SRS offer exceptional performance and value. These RGA’s provide detailed gas analysis of vacuum systems at about half the price of competitive models. Each RGA system comes complete with a quadrupole probe, electronics control unit (ECU), and a real-time Windows software package that is used for data acquisition and analysis, as well as probe control.
