KGD - YQ - 504 Portable Greenhouse Gas (CO₂/CH₄/N₂O) Emission Analyzer
KGD - YQ - 504 Portable Greenhouse Gas (CO₂/CH₄/N₂O) Emission Analyzer
Product Introduction
The KGD - YQ - 504 Portable Greenhouse Gas (CO₂/CH₄/N₂O) Emission Analyzer adopts micro - flow infrared half - cell gas sensing technology. It can simultaneously and accurately measure the concentration changes of greenhouse gases such as CO₂, CH₄, N₂O, as well as CO gas in flue gas. The measuring range can be as low as 200 ppm, with an accuracy of up to 1% F.S. It has strong resistance to gas cross - interference and lower drift. It is equipped with an integrated sampling and tracing heating device, a portable pretreatment device, and can expand measurement indicators such as flue gas temperature, pressure, and flow rate to realize the statistics of emission rate and total emissions.
Meanwhile, to meet the measurement requirements for high - concentration CO₂ and medium - to - high - range CO, sensor modules with the company's independent intellectual property rights of Non - Dispersive Infrared (NDIR) gas sensor technology can be optionally configured flexibly. These modules feature 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.
- It is a portable instrument, equipped with high - performance sampling and pretreatment devices.
