Fuel Sniffer
Fuel Dilution Meter

Overview
"The Fuel Sniffer was developed in collaboration with the U.S. Navy."
Application
The Fuel Sniffer is a portable fuel dilution meter that can be used in
the laboratory or in the field to provide rapid and accurate measurements of fuel
contamination in engine oils.
Operation
The Fuel Sniffer needs just over 60 seconds to perform each measurement.
The next sample can be introduced quickly with the specially designed "clamp and
sample" bottle platform, so that 40 or more samples can be measured per hour. The
sample bottle platform also keeps the sample bottle below the level of the instrument
to prevent potential damage due to liquid sample coming in contact with the sensor.
A single-point calibration, using a 5% fuel/oil standard, is as fast to run as a sample, so the Fuel Sniffer is soon ready to make accurate measurements. Accuracy is comparable to that achieved by gas chromatography, but without all the time, expense and inconvenience. The percentage fuel dilution is displayed on the backlit LCD display and can also be sent to a printer or external computer via built-in RS 232 output.
Principal of Fuel Measurement
Developed in collaboration with the U.S. Navy, the Fuel
Sniffer employs a Surface Acoustic Wave (SAW) Vapor Microsensor to measure the concentration
of fuel in used lubricating oil samples by sampling the "headspace" in the sample
bottle. The instrument assumes (based on Henry's Law) that the fuel vapor concentration
is directly related to the fuel present in the oil sample. A pump inside the instrument
draws headspace vapors across the SAW sensor which detects adsorbed hydrocarbons
by a change in frequency of a surface acoustic wave (SAW).
