Flue Gas Analyzer SO2 Gas Concentration Analyzer
The KF100 Flue Gas Ultraviolet Analyzer, based on UV absorption spectroscopy 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 foreigh competing products.
>>> Technical Features
1) The analyzer gets the UV absorption spectrum from the following optical technology platform that consists of a light source, a gas chamber, fiber optics, a spectrometer(including a diaphragm, holographic gratings, and a linear array )
2) The UV-visible light emitted from the light source enters into the gas chamber through the optical window, where it is absorbed by the sample gas flowing through the gas chamber. Then the light carring the absorption information of the tested samples gas is converged by a lens and coupled into 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.
3) By using the DOAS technology to analyze the spectrum, the concentration of relevant contents in the gas can be analyzed.
>>> Measuring principle
1) The light souce emits ultraviolet beam which transfers to gas cell through optical fiber.
2) After absorption by measuring gas, the light beam transfers through optical fiber to spectrometer.
3) Being dispersed through the grating, and converted into electric signal by the array sensor, a continuous absorption. spectrum of measuring gas is thereafter obtained.
