OBS-ONE IRLAM Unit

NH₃/N₂O 대응용 차량 탑재형 배기가스 측정 장치

OBS-ONE IRLAM은 실제 주행 조건에서 NH₃/N₂O를 분석하기 위한 차량 탑재형 배기가스 측정 시스템으로, 향후 시장의 규제에 대응하기 위해 탄생했습니다.

IRLAM 유닛은 Gas 유닛 및 PN 유닛과 결합하여 기존에 배기가스 구성 요소와 함께 배기가스 유량, GPS 위치 및 대기 조건(온도, 습도, 압력)을 측정할 수 있습니다.

RDE Test with Portable Emission Measurement System (PEMS)

In 2016 the European Commission´s (EC) Member States agreed on new procedures and requirements for light-duty vehicle type approval certification introducing Portable Emission Measurement System (PEMS) for vehicle testing on the road.

Real driving emissions with RDE CoDriver

Real Driving Emission (RDE) tests confirm the results produced during an emissions test on a chassis dynamometer to ensure that vehicles meet the set limits in the real world.

RDE Testing for Non-Road Mobile Machinery (NRMM)

After the introduction of Real Driving Emission (RDE) tests for light- and heavy-duty vehicles, focus is now also shifting to the area of non-road mobile machinery (NRMM).
