KGD - YQ - 501 Greenhouse Gas (CO₂/CH₄/N₂O) Emission Analyzer
Product Introduction
The KGD - YQ - 501 Greenhouse Gas (CO₂/CH₄/N₂O) Emission Analyzer
employs micro - flow infrared half - cell gas sensing technology.
It enables simultaneous and accurate measurement of concentration
changes of greenhouse gases such as CO₂, CH₄, N₂O, as well as CO
gas in flue gas. The measuring range can reach as low as 200 ppm,
with an accuracy of up to 1% F.S. It features strong resistance to
gas cross - interference and lower drift.
Moreover, to meet the measurement requirements for high -
concentration CO₂ and medium - to - high - range CO, sensor modules
with Non - Dispersive Infrared (NDIR) gas sensor technology can be
optionally configured for flexibility. These modules are
characterized by good stability, small size, and low cost.
Product Features
One analyzer can simultaneously and continuously measure up to five
gases, including CO₂, CH₄, N₂O, CO, and O₂.
For CO₂, CH₄, N₂O, and CO, the patented micro - flow infrared
technology can be selected, with a measuring range as low as 200
ppm and an accuracy of up to 1% F.S.
Small drift, resistant to moisture interference, and stable for
long - term use.
For medium - to - high - concentration measurement needs, dual -
beam infrared sensing technology can be used to measure CO₂ and CO,
allowing for flexible combinations.
It has both digital and analog signal output functions, enabling
simple and convenient data management.
