Spectro Scientific – Battery Powered Oil Analyzers – FDM 6000 – Portable Fuel Dilution Meter

The FDM analyzer employ a Surface Acoustic Wave (SAW) vapor sensor to measure the concentration of fuel in used oil samples by sampling the “headspace” in the vial. The device assumes (based on Henry’s Law) that the fuel concentration in the headspace vapor is directly related to the fuel present in the oil sample. The surface of the SAW sensor has a polymer coating with specific solubility to fuel vapors. The sample pump draws the headspace vapor through the SAW sensor where it is absorbed onto the polymer coating and detected. The purge pump then pushes air through the SAW to clean the system so it is ready for the next sample.
