The InfraCal 2 Biodiesel Blend Analyzer for measuring percent biodiesel in diesel is the ideal solution where a quick, accurate, on-site measurement is required and a single, repetitive biodiesel blend analysis is needed. The InfraCal 2 ATR-B is based on proven IR technology, originally developed by Wilks, and used by fuel distributors, blenders, producers and regulatory agencies worldwide.  The compact, easy-to-use Biodiesel Blend Analyzer has a measurement range of 0 – 100% biodiesel in diesel. These results are comparable to both ASTM D7371 and EN 14078, laboratory methods that require expensive FTIR Spectrometers.

Samples are applied to a zinc selenide attenuated total reflectance (ATR) sample plate for immediate results. The analysis can be done by non-technical personnel with no formal training and is ideal for lab or field use. The InfraCal2 ATR-B has a touch screen display, internal data storage and transfer, a multi-language interface and password protected settings.  The internal battery pack allows for portability and up to 6 hours continuous use, providing results in under a minute at a fuel loading rack, in a laboratory or at a pump in a fueling station.
