Uses pulsed fluorescence technology to measure the amount of sulfur dioxide in the air up to 100ppm. The pulsing of the source lamp serves to increase the optical intensity whereby a greater energy throughput and lower detectable SO2 concentration are realized. 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.
Key Features:

  • Pulsed fluorescence technology
  • 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
