Portable Fuel Analysis Dilution Meter: The Spectro FDM Q600

The Spectro FDM Q600 portable fuel analysis dilution meter is designed to provide fast and precise measurements of fuel contamination in engine oil. The instrument is suitable for both field and laboratory applications.

The fuel analysis dilution meter employs a surface acoustic wave (SAW) vapor microsensor to assess the concentration of fuel in lubricating oil samples. It uses a pump to direct headspace vapors towards the SAW sensor, which identifies the absorbed hydrocarbons through a frequency change in SAW.
