KGD-WQ-504 Portable Emissions Tester (PEMS)

KGD-WQ-504 Portable Emission Testing System (PEMS)

Product Introduction

The KGD-WQ-504 Portable Emission Testing System is specifically designed for in - use vehicle on - road emission tests. It can continuously and real - time measure or collect the volume concentrations of air pollutants such as CO, CO₂, NO, NO₂, NOₓ, O₂, and THC, as well as particulate matter number concentration, exhaust gas flow, global positioning data, meteorological data, OBD parameters, etc. It has functions such as test process guidance, automatic calculation of total emissions, and export of test reports, and can meet the certification tests, in - use compliance tests, and related research and development test requirements of global vehicle on - road emission regulations.

Product Features

  • Core sensing technology under independent control
  • One - stop service throughout the whole life cycle
  • Small in size, light in weight, and low in energy consumption
  • Easy to install and use, with a lithium - ion battery life of over 8 hours
  • Modular design, plug - and - play
  • Flexibly meet the needs of various regulatory and R & D tests
  • High - standard waterproof and shockproof
  • Maintain stable test performance under various harsh working conditions
