Suflur dioxide analyzer

The outcome is an ultra compact and light- rack 3U, easy-to-use analyzer capable of measuring sulphur dioxide at ppb levels. Applied to SO2 measurement, the universally known UV fluorescent principle consists in detecting the characteristic fluorescence radiation emitted by SO2 molecules. In the presence of a specific wavelength of UV light (214 nm) the SO2 molecules reach temporary excited electronic state. The subsequent relaxation produces a fluorescence radiation which is measured by a non-cooled photomultiplier tube (PM).
