Product Details
KGD - WQ - 524 Zero Gas Generator for Vehicle Exhaust Detection
Product Introduction
The KGD - WQ - 524 Zero Gas Generator is a supporting application
device for vehicle emission gas analyzers in detection stations. It
is used for zero - point adjustment and calibration of exhaust gas
analyzers for gasoline and diesel vehicles, span calibration of
oxygen sensors, and back - flushing of gas paths. It is compatible
with various analytical instruments for measuring vehicle exhaust
using infrared, ultraviolet, and infrared plus converter furnace
methods. This product complies with the requirements of zero - gas
standard gas specified in national standards GB18285 - 2018, GB3847
- 2018, and HJ1237 - 2021, and can replace cylinder zero gas,
greatly reducing the operating costs of detection stations.
Product Features
- The output zero - gas flow is ≥ 16L/min, and the output pressure
and flow are adjustable.
- An efficient water - removal system with automatic drainage,
unaffected by the dew point of the inlet air.
- Reasonable structure, capable of calibrating 4 or more exhaust gas
analyzers simultaneously.
- Stable and reliable performance, with a service life of up to 6
years for the entire machine.
- Simple operation and low daily maintenance requirements.
