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
