The Dekati® MPEC+™ (Mobile Particle Emission Counter) is a compact, portable instrument designed for a wide range of mobile and stationary particle number (PN) measurements. At its core is the patented Dekati® ePNC™ particle counting technology, further optimized for dynamic emission measurements in the ultrafine particle (UFP) size range. The MPEC+™ delivers accurate, repeatable, and reliable PN measurements for both testing and continuous monitoring applications. It is ideally suited for mobile measurements, including on- and off-road real-driving emissions (RDE), marine PEMS, and automotive non-exhaust emissions (NEE), as well as stationary applications such as generator sets, data centers, industrial workplaces, and airport UFP emission monitoring. Thoroughly tested under some of the world’s most demanding field operating conditions, the MPEC+™ provides durability and performance whenever accurate PN measurements are required, and can be used as a stand-alone instrument or easily integrated into a larger measurement system.
