PEMS Pro-Cart Vehicle

(Mobile Emission Measurement Van & Workstation)

As per regulatory requirements under BSVI norms and upcoming CEV/TREM Stage V standards, real-world emission measurement is critical.The PEMS Pro-Cart is designed to meet this need by enablingReal Drive Emission (RDE) testing andIn-Service Conformity (ISC) checks across diverse terrains and customer sites.

Key Highlights of PEMS Pro-Cart

  • ✅ Integrated Mobile Workstation:
    Comfortable workspace for engineers and customer representatives with power outlets and AC for optimal conditions.
  • ✅ On-Site Capability:
    Equipped with a 1-ton crane for smooth loading/unloading of PEMS equipment, safe storage for gas cylinders, and ventilation for safety.
  • ✅ Self-Sufficient Power:
    Portable genset and air-conditioning ensure uninterrupted operations at remote locations.
  • ✅ Versatile Applications:
    Ideal for RDE tests on highways, mines, construction sites, and farms for non-road applications.

This innovation will transform field emission testing,offering real-time data monitoring, analysis, and maintenance support at the test site.
