ERASPEC is Eralytics? industry-proven multi-fuel analyzer with several thousand installations worldwide. It offers measurements of fuel component concentrations and of complex parameters like RON or cetane number for gasoline, diesel fuel, jet fuel and even specialized fuels like ethanol fuels. A single push of a button delivers all results in only 1 minute.

ERASPEC is a patented, rugged portable FTIR spectrometer. It is a stand-alone instrument that can be operated in the lab, in mobile laboratories and in the field.

The ERASPEC handheld FTIR analyzer comes already with factory-installed databases and they can easily be expanded by the user. These databases provided by Eralytics are tailor-made to the typical needs within a given country or region. Adding customer samples to the databases is as easy as running a measurement and entering the corresponding reference values afterward.
