WebPEMS is a generic term that encompasses all portable emissions measurement systems. Two EPA-developed examples are ROVER (Real-time On-Vehicle Emissions Reporter) for on-highway applications, and SPOT (Simple Portable On-vehicle Tester) for non-road applications. Now, however, several commercial instrument manufacturers offer … WebSUMMARY: Our PEMS – Predictive Emissions Monitoring System, is a state-of-the-art, extremely reliable (over 99% uptime) and significantly cheaper (more than 90%) alternative to the hardware based CEMS – Continuous Emissions Monitoring System. REGULATORY APPROVALS: It is approved by US EPA and most international regulatory agencies.
