PRODUCT DESCRIPTION
The Thermo Scientific range of iSeries gas analysers have by far and away the least requirement for maintenance of any gas analysers on the market today and are built for reliable continuous duty field gas detection.
Using pulsed fluorescence technology this analyser measures the amount of sulphur dioxide in the air and 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 realised. 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.
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 and the larger interface screen can display up to five lines of measurement information.
