Product Details
KGD - WQ - 501 Engine Emission Testing System for Engines
Product Introduction
The KGD - WQ - 501 Engine Emission Testing System is an integrated
system device specifically designed for measuring conventional gas
components such as THC, CH4, NOx, CO2, CO, and O2 in full - flow
dilution or raw exhaust emission tests in laboratories. It includes
functional modules such as a sampling unit, a pre - treatment unit,
and various gas analyzers, and is applicable to research,
development, and certification tests of all types of engines and
fuels.
Product Features
- Adopts self - developed patented gas sensing technologies such as
NDIR, NDUV, CLD, and HFID, with one - stop service throughout the
life cycle.
- The gas analyzer has a wide measurement range, suitable for all
laboratory emission test application scenarios including ultra -
low emission levels.
- The gas analyzer has high accuracy and fast response, enabling high
- precision continuous online measurement of diluted exhaust and
raw exhaust.
- Can be equipped with a multi - channel multifunctional sampling
unit to flexibly respond to multi - point sampling measurement of
exhaust pipes and EGR rate measurement.
