Goods Description:A change is in the air The industry’s new best-of-breed. Our customers told us exactly what they’re looking for in a gas monitoring solution: reliability, simplicity, ease of use. The new iSeries platform delivers on all counts - and then goes a step farther. A core product in Thermo’s new iSeries product line is the Model 43i SO2 analyzer.


Using pulsed fluorescence technology, the Model 43i measures the amount of sulfur dioxide in the air up to 10ppm. The pulsing of the U.V. source lamp serves to increase the optical intensity whereby a greater U.V. energy throughput and lower detectable SO2 concentration are realized.  Reflective bandpass filters, as compared to commonly used transmission filters, are less subject to photochemical degradation and more selective in wavelength isolation.  This results in both increased detection specificity and long term stability.

This state-of-the-art gas analyzer offers features such as an ethernet port as well as flash memory for increased data storage.  Ethernet connectivity provides efficient remote access, allowing the user to download measurement information directly from the instrument without having to be on-site.

You can easily program soft-keys to allow you to jump directly to frequently accessed functions, menus or screens  The larger interface screen can display up to five lines of measurement information while primary screen remains visible.
