Thermo Fisher 43i SO2 Analyzer




The Thermo Scientificâ„¢ Model 43i utilises pulsed fluorescence technology to measure SO2 in ambient air up to 100ppm .

The 43i reflective bandpass filters are less subject to photochemical degradation and more selective in wavelength isolation, resulting in both increased detection specificity and long term stability. The Model 43i SO2 Analyzer is also available with an oxygen sensor module which allows the user to correct the  SO2 reading for the amount of Oxygen in the sample.
