Portable Infrared Flue Gas Analyser KGD - YQ - 520 For Environmental Monitoring Stations
Portable Infrared Flue Gas Analyzer KGD - YQ - 520 for Environmental Monitoring Stations
Product Introduction
The KGD - YQ - 520 Portable Infrared Flue Gas Analyzer uses non - dispersive infrared gas sensors and electrochemical gas sensors, and is equipped with an imported integrated sampling and tracing device, as well as an imported portable pretreatment device. It can simultaneously measure the volume concentrations of gases such as SO₂, NO, CO, CO₂, and O₂ in flue gas components, as well as parameters such as flue gas temperature and flow rate, and calculate the emission rate and total emission amount. It is a high - performance portable product specifically developed for environmental supervision, energy - saving supervision, energy - efficiency testing, and environmental scientific research. It has won the title of "National Key New Product" and has been widely used in environmental monitoring stations, energy - saving supervision centers, and special inspection institutes at all levels in China.
Product Features
- High Measurement Accuracy: Using non - dispersive infrared gas analysis technology with independent intellectual property rights and long - life electrochemical sensing technology, there is no cross - interference between multi - component measurement gases, ensuring high measurement accuracy.
- High Data Portability: Automatically stores measurement data, and can automatically calculate the excess air coefficient and combustion efficiency. Equipped with a pin - type printer and a USB communication interface, it can print real - time and historical stored data, or directly export the stored data to a USB flash drive.
- Powerful Measurement Index Expansion Function: Can simultaneously measure the volume concentrations of multiple gases in flue gas components, and can expand measurement indices such as flue gas temperature, pressure, flow rate, ambient temperature, and pressure.
- High - Performance Sampling and Pretreatment Devices: The analysis main unit is simultaneously equipped with an imported original integrated sampling and tracing device, and an imported original portable pretreatment device made of aluminum alloy material, ensuring that the sample gas meets the requirements of the instrument.
