OBS-ONE PM unit

OBS-ONE PM - On-board Emissions Measurement

차량 탑재형 배기가스 측정 장치

차량 운행 중에도 배기가스 측정이 가능한 온보드 배기가스 측정 시스템으로 PM(입자상 물질)을 실시간으로 측정이 가능합니다. 벤투리 유량계를 사용하여 설계하였으며 가스 유닛과 PM 유닛의 결합으로 대형 및 비도로 차량에 대한 인증 테스트에 적합합니다.

Segment: Automotive
Manufacturing Company: HORIBA, Ltd.

 EPA CFR part 1065 Compliance

For Certification

  • US EPA CFR part 1065 subpart J
  • Simplify data collection and post-processing regulation requirements by using this measurement method

For R&D

  • Easily compare in-lab test results with real-road test results
  • Support R&D by simulating real-world driving events in the test cell with the Test Automation System STARS

 

◎ The world’s smallest PM measurement system in its class*

     *As of July 2015. Based on our company's research.

  • Easily mounted on any vehicle (modular and front access design)
  • One-touch fitting for module and cable connections

 

◎ The reliable test method for high speed flow rate control

  • PM transient measurement by proportional sampling

 

◎ User-friendly design mounts easily on any vehicle
   (modular and front-access design)

  • One-touch fitting for module and cable connections
  • Cartridge filters are easily changed 

Integrated Operation Software

OBS-ONE and other HORIBA ONE series measurement devices employ a common interface with future expandability. Control and management of each emission measurement device can be integrated into a single controller, as well as provide notifications of system health.
