Using pulsed fluorescence technology, the Model 43i-TLE measures the amount of sulfur dioxide (SO2) in the air down to 50ppt. Dual sets of reflective bandpass filters are less subject to photochemical degradation and more selective in wavelength isolation thus resulting in both increased detection specificity and long term stability.
