Bruker Optics Inc. has announced the FUELex, a dedicated portable fuel analyzer for rapid and simultaneous analysis of multiple jet and diesel fuel properties. It uses an extensive fuel library built from numerous commercial and military sources and is suitable for monitoring changes in jet and diesel fuel quality, providing results on more than 12 properties simultaneously. Using a fiber optic dip probe, FUELex sampling consumes no fuel and requires no special sample preparation. Current sample type capabilities include Jet A, Jet A-1, JP5, JP8, Diesel and Diesel 1. Results are ready in <3 s after activating the measurement. The device permits multiple properties of the sample fuel to be measured simultaneously and correlated to American Society for Testing and Materials parameters.
