Emissions Analysis System

This full featured, fully digital emission analysis system is the most cost effective solution for light and heavy duty emission analysis. The bench communicates with other test cell computers via an Ethernet link in a Windows XPTM environment for a truly integrated test cell. This cost effective system can be integrated with virtually any manufacturers analyzers. For specific applications contact the engineering staff at RISI.
