Product Description This biodiesel analyzer is for the determination of the content of fatty acid methyl esters (FAME) biodiesel in diesel fuel oils. The Biodiesel Blend Analyzer is a low-cost, single wavelength analyzer with filters preset for a particular measurement. Biodiesel has a characteristic infrared absorption band at 5.73 ìm (1745 cm-1). As the biodiesel percentage increases, the infrared absorbance increases. An internal calibration table in the Biodiesel Analyzer converts infrared absorbance to a digital readout in percent. A fuel sample is placed directly on the exposed ATR sample window and after 10 seconds the percent biodiesel is displayed. The fuel is easily cleaned off the window using a solvent and a wipe and the analyzer is ready for the next sample. An RS 232 interface is available for data transmission to a PC. The Biodiesel Blend Analyzer is ideal where a single, repetitive analysis is needed.
- Single Wavelength Analyzer - dedicated single analysis
- Fast - Results in less than one minute
- Portable - 6.5 x 6.5 x 5 inches (16.5 x 16.5 x 12.7cm), can be battery operated
- Affordable - less costly than most other measurement techniques
- Lightweight - less than 5 lbs
- Direct readout in desired units
- Data Transfer - RS-232 connections or printer

This analyzer is extremely easy to use and to keep clean. Simply drop approximately 2mL on the test plate of the instrument and press the start button. In about 30 seconds the instrument will display the results for you. After testing, add enough hexane or appropriate solvent to cover the plate. Then wipe slowly in one direction until it's clean and you will be ready to test your next sample. It comes with a universal AC/DC power supply, and can even be battery operated for portable use.
Biodiesel in Blend Analyzer 0-30% OR 0-100% (please request price on the 0-100% model K25554). Upgrade from 0-30% to 0-100% is easily done on site with a set of calibration standards or at the factory.
