SO2 Analyzer

43i with datasheet

Measure SO2 in ambient air up to 100ppm with the Thermo Scientific™ Model 43i SO2 Analyzer. The first gas analyzer to utilize pulsed fluorescence technology to measure SO2. 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.


  • High sensitivity and fast response time
  • Linearity through all ranges
  • Internal sample pump
  • Insensitive to changes in flow and ambient temperature
