Spectro FDM Q600 Portable Fuel Analysis Dilution Meter from Spectro Incorporated

The Spectro FDM Q600 from Spectro Inc. is a portable fuel analysis dilution meter that provides both laboratory and field measurements of fuel contamination in engine oil.

The instrument uses a surface acoustic wave (SAW) vapor microsensor for the measurement of fuel concentration in lubricating oil samples. A pump inside the device directs headspace vapors towards the SAW sensor, which determines the absorbed hydrocarbons through a frequency change in SAW.
