The new Dekati® MPEC+™ (Mobile Particle Emission Counter) is a compact and portable instrument for easy onboard PN-PEMS measurements.
At the core of the MPEC+™ is the patented Dekati® ePNC™ particle counting technology, which has been further optimized for fast transient emission measurements. The MPEC+™ is the device of choice for highly accurate PN-PEMS testing in accordance with RDE requirements. The Dekati® MPEC+™ has been extensively tested and verified in some of the harshest driving and climate conditions to make sure it always delivers superb measurement performance.
The MPEC+™ system consists of the Dekati® ePNC™ particle counter combined with a sample conditioning system that allows direct connection to raw exhaust gas. The innovative Dekati® ePNC™ particle counting technology is based on diffusion charging, diffusion particle collection and electrical detection of collected particles. Its patented low-pressure operation provides an electrical current signal that is directly proportional to particle number (PN) concentration. For RDE purposes, the ePNC™ has been further enhanced to accurately measure exhaust particle concentration in transient conditions.
