Model 43i SO2 Analyzer

Catalog number: 43I
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.

Discover the iQ to work smarter with our next generation 43iQ Sulfur Dioxide Analyzer.

Key Features:

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

iSeries Advantage:

  • Ethernet connectivity for efficient remote access
  • Enhanced user interface with one button programming and large display screen
  • Flash memory for increased data storage and user downloadable software
  • Enhanced electronics design optimizes product commonality
  • Improved layout for easier accessibility to components

The Model 43i SO2 Analyzer is also available with an oxygen sensor module.

The Model 43i with Oxygen uses paramagnetic sensor technology to extend the possibilites of SO2 measurment, reading and reporting the concentration of oxygen in the sample stream up to 100%. Additionally, programming allows the user to correct the SO2 reading for the amount of oxygen in the sample.
