The PEMS compact measuring system enables the mobile emissions measurement during a real road trip.

Compact Portable Emission Measurement Systems
PEMS (Portable Emission Measurement System) / RDE (Real Driving Emissions)

PEMS Gen2 is a compact and mobile emission measurement system for real driving emissions (RDE) with focus on the legal vehicle type test in Europe. Sampling can be done at the exhaust or via the EFM (Exhaust Flow Meter). High priority was given to robust and precise measurement technology as well as intuitive assembly and handling.



  • Very compact device to facilitate assembly
  • Easy and flexible vehicle assembly to minimize set-up times
  • Low weight to facilitate handling and enable use for small cars
  • High robustness and suitability for all weather conditions, so that outdoor installation is possible
  • Simple operating concept and handling to shorten the individual test steps and minimize errors
  • Precise measurement even under changing test conditions (NVH, Temperature, pressure)


  • RDE measurement according to:
    • (EU) 2017/1151 with the additions 2017/1154, 2017/1347 resp. regulation (EU) 2018/1832
    • China C6, GB 18352.6-2016
    • Korea MOE notification
    • Indien Bharat 6
    • UN ECE R49
    • Non-road Stage V
  • Measurement of CO2, CO, NO, NO2 directly at the exhaust or via sample taking at the EFM
  • Optional measurement of THC, CH4, NH3 and N2O with additional hardware
  • Developement rides dnd 'Road-to-Rig' rides



Options PEMS
Analyzers fulfill Euro 6c RDE requirements (accuracy, drift, noise, response time, linearity). No NOX converters are necessary.
Measurement and analysis of the exhaust particle number emissions directly from the vehicle, while on an actual road trip.
The PN-system can be combined with the AIP PEMS-GAS in a weather proof protective and robust case (IP67) as a combined stand-alone unit. It is possible, to combine the system with a AIP exhaust flow meter.
Exhaust gas mass flow meter for the parallel use with additional PEMS units.
Remote control of the desktop applications via web service for visualization of instantaneous emissions and pollutant concentration during a road test drive.
