Vehicle Mass Analysis System (VMAS) is a recent breakthrough in vehicle emission testing. VMAS allows for a low cost, reliable and accurate means of determining mass in centralized and decentralized vehicle Inspection/ Maintenance (I/M) programs.
The product utilizes an innovative technique for measuring exhaust volume. This technique, coupled with current low cost NDIR gas analyzers, provides for a highly accurate and repeatable mass measurement system suitable for transient, steady state, and even idle test procedures.
