Flue gas ultraviolet analyzer for SO2 NO NO2
,Industrial UV gas analyzer for emissions
,Ultra-low emissions monitoring system with warranty
The KF100 Flus Gas Ultraciolet Analyzer, based on UV absorption sepctroscopy technology and chemometric algorithms, can be used to measure the concentration of SO2, NOx, O2, NH3, CL2, O3, H2S and other gases. With high accuracy, high reliability, fast response, and wide applicability, it can be widely used in online environmental monitoring, industrial control, security monitoring and other occasions. The performance indicators of the KF100 series have reached or exceeded those of other domestic and foreign competing products.
>>>Technical Features
The analyzer gets the UV absorption spectrum from the following optical technology platform that consists of a light source, a gas chamber, fibre optics, a spectrometer(including a diaphragm, holographic gratings, and a linear array detector) and other optical components.
The UV-visible light emitted from the light source enters into the gas chamber through the optical windows, where it is absorbed by the sample gas flowing through the gas chamber. Then the light carrying the absorping information of the tested sample gas is converged by a lens and coupled inyp the optical fibre. After the light is transmitted into the spectrometer through the optical fibre for light splitting and sampling, the absorption spectrum of the gas can be obtained.
By using the DOAS technology to analyze the spectrum, the concentration of relevant contents in the gas can be analyzed.
>>>Technology Comparison
| Item | UV Hot-Wet Method | NDIR |
| Spectral Range | Complete and continuous absorption spectra obtained through holographic grating and diode array detection | Non Dispersive, characteristic absorption spectra obtained through band-pass filter |
| Linear Response | High wavelength resolution secures linear response | band-pass filtration compromises linear response |
