The UV Flue Gas Analyzer KGD - YQ - 515 For Online Measurement Of Flue Gas Concentrations
The UV Flue Gas Analyzer KGD - YQ - 515 is used for online measurement of flue gas concentrations.
Product Introduction
The KGD - YQ - 515 UV Flue Gas Analyzer is based on ultraviolet differential absorption spectroscopy gas analysis technology. It adopts a unique algorithm and a long - optical - path multiple - reflection gas cell, featuring high sensitivity, strong absorption signal, long service life, good stability, and being free from water vapor interference. It can simultaneously measure the gas concentrations of SO₂, NO, and NO₂ in flue gas components online, meeting the needs of the ultra - low emission monitoring market.
Product Features
- The light source uses imported deuterium lamps, ensuring high stability.
- Excellent performance with a linear error ≤ ± 1%F.S.
- Stable constant - temperature control to reduce the impact of ambient temperature.
- Optimized absorption peak and interference compensation algorithm with minimal cross - interference.
- Touch - screen display interface for convenient operation.
- Two - way RS232/485 serial port output to meet the requirements of environmental protection direct data acquisition instruments.
- Dual - range design with a range ratio of up to 1:10.
- With pump and valve control output, it can be externally connected to an air pump and solenoid valve to control the gas path for automatic calibration.
