The ERASPEC OIL is a portable, stand-alone infrared analyzer for high-speed lubricant oil analysis and condition monitoring. This instrument?s patented interferometer design delivers laboratory-grade results directly on site and is in full compliance with ASTM, DIN and JOAP methods. ERASPEC OIL fuel analyzer measures contaminants, degradation products, additive depletion as well as calculated properties like TAN, TBN, and viscosity within seconds.

Lubricant oils exhibit various chemical changes during their lifetime. This starts with simple changes such a fuel dilution of the fuel used or the uptake of soot (ASTM E2412) from the combustion. Numerous chemical reactions with combustion products lead to oxidation (ASTM D7414), nitration (ASTM D7624), or sulfation (ASTM D7415) of the lubricant and can be summarized as degradation products. All of them can be readily monitored by IR spectroscopy with the ERASPEC portable oil analyzer.

Eralytics? patented rugged and light-weight FTIR spectrometer design allows measurements giving results as previously known from laboratory systems only. With its weight of only 8 kg and the ability to be powered by a vehicle battery, ERASPEC portable oil analysis equipment can easily be brought on-site or even remote locations. There is no need to send in samples for analysis anymore.

features__astm compliantERASPEC OIL is fully compliant with ASTM D2896, ASTM D445, ASTM D664, ASTM D7412, ASTM D7414, ASTM D7415, ASTM D7418, ASTM D7624, ASTM E2412, providing both standard method and refined methodology.
features__simple operatonAll eralytics analyzers use an intuitive menu structure that is easy to navigate. Samples need no prior preparation and measurements are done fully automated.
A direct out-of-the-box connection to LIMS (Laboratory Information Management System) is established with a standard Ethernet cable.No extra software or PC are necessary.
features__footprintThe small footprint of the eralytics instruments makes them the first choice for use in the lab and on-site.
features__portableThe Eralytics units are all lightweight and built with an integrated carrying handle, they are versatile and ideally suited for mobile applications as well.

features__touch screenAll Eralytics analyzer results are displayed immediately after the test on their large and user-friendly color touch screen.
