Product Details
KGD-WQ-507 Dual - channel Direct - sampling Gas Emission Analyzer
Product Introduction
The KGD-WQ-507 Dual - channel Direct - sampling Gas Emission
Analyzer combines high - precision Hydrogen Flame Ionization
Detection (HFID) technology, Non - Dispersive Ultraviolet (NDUV)
gas analysis technology, Chemiluminescence Detection (CLD) gas
analysis technology, Non - Dispersive Infrared (NDIR) gas analysis
technology, and Magnetic - Parametric Detection (MPD) technology.
It simultaneously measures the volume concentrations of gases such
as THC, CH₄, NOₓ, CO, CO₂, and O₂ in the raw exhaust of engine
tailpipes, as well as the volume concentration of CO₂ in the EGR
pipeline gas. It can provide engine manufacturers, testing
institutions, and scientific research departments with a complete
system testing solution for detecting and analyzing engine exhaust
pollutants to meet the increasingly strict and flexible emission
limits.
Product Features
- Simultaneously measures THC, NOₓ, CO, CO₂, O₂, and can be extended
to measure CH₄, NMHC, NH₃, N₂O, etc.
- NDUV technology directly measures NO and NO₂ without the need for a
converter furnace, requiring no maintenance. The CLD technology can
be optionally equipped to measure NOₓ.
- Real - time analysis of gas components at multiple tailpipe
sampling points simultaneously.
- Multi - point sampling and real - time analysis of the volume
concentration of CO₂ in the complete EGR gas path.
- Integrated design, highly automated, and easy to operate.
- High measurement accuracy, fast response speed, and performance
reaching the standards of imported equipment.
