InfraCal2 – Biodiesel

Oil-Analysis-InfraCal 2 ATR-B



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 is based on proven IR technology, originally developed by Wilks, and used by regulatory agencies and fuel terminals worldwide.  The compact, easy-to-use InfraCal 2 has a measurement range of 0 – 100% biodiesel in diesel and an accuracy of +/- 0.2. These results are comparable to both ASTM D7371 and EN 14078.


Samples are applied to a scratch-resistant zinc selenide attenuated total reflectance (ATR) sample plate and easily cleaned with a cloth or paper towel.  No solvents requiring special ventilation, expensive waste disposal or difficult to clean cells are needed. The analysis can be done by non-technical personnel with no formal training and is ideal for lab or field use. The InfraCal2 has added features such as touch screen display, data storage and transfer, a multi-language interface and password protected settings.  The internal battery pack allows for portability and up to 12 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.


  • Measurement range: 0 – 100% biodiesel
  • Instrument repeatability: +/- 0.2
  • Compares to ASTM D7371 & EN 14078


Features & Benefits






The InfraCal 2 Model ATR-B is shipped factory calibrated for 0 – 100% Biodiesel in Diesel percent measurement.  The calibration range includes ten points; 0, 2, 5, 10, 15, 20, 25, 30, 50, 75, 95 &100%.  The calibration is performed using biodiesel in High Cetane diesel fuel prepared by a certified laboratory.
