TheDR10measuresthedepositthicknessat1,200 pointsaroundthesurfaceofthetube.Attheendof thetest,itdisplaysa3Dmappingofthedepositin addition to average and maximum thicknesses and totalvolumedeposit. Applications TheDR10isdesignedforalltypesofapplicationsrelated to thermal oxidation testing of jet fuels including research, refining, pipeline, terminals, and mobile laboratory applications every location where thermal oxidationofjetfuelisevaluated. Principle TheDR10usesaninterferometrytechniquebasedon a powerful light source, a fiber optic probe, and a spectrometer.Specificlightisemittedonthesurfaceof thetube. Lightsource Deposit thickness Reflected light Interference between thewavetrains Deposit Aluminum tube The reflected light is collected and the light interferencecreatedbythedepositisanalyzedwitha spectrometer.

A virtual alphanumerickeypadisusedtoprogramthetest.The sample types, the operator names and test temperaturesarepreprogrammed.OnlythesampleID and the tube serial number have to be entered. The tube serial number is displayed by a camera and the techniciansimplyentersthedisplayedserialnumberat the beginning of the test. With this minimal data entry, the 1,200 points tube scanning is initiated. The fulltubescaniscompletedinlessthan15minutes. TheDR10displaysa3Dimageofthedepositandthe average and the maximum thickness deposit values. The mean deposit thickness of the thickest 2.5 mm2 area defined in the ASTM D 3241 is reported in additiontothecalculatedtotaldepositvolume.
