General Description
TheSensit®InfraredEthaneDectector,referredtoas“IRed”,isdesignedtodetectthepresenceof
ethaneinamethanesample.TheIRedcandetect250partsperbillion(ppb)upto1000ppmethane.
TheIRedisusedtodetermineifmethanedetectedintherangeof50-2000ppmisofsimilarmake-up
tothatofpipelinegas(whichcontainsethane)orisnaturallyoccurringmethanefromothersources
suchasorganicdecay.TheIRedisnotdesignedforhighconcentrationsordeterminingactualethane
contentfromwithinapipeline.
TheIREDsensesgasusingInfrared(IR)AbsorptionSpectroscopyincombinationwithanelectronic
narrowbandpasslter.Thistechnologyutilizesaninfraredlightsourcewithanoutputthatischanged
when certain gases absorb the light output.  The lter only allows specic light wavelengths to be
monitoredandmeasured.TheconcentrationofgasisproportionaltotheamountofspecicIRlight
absorbedandisdisplayedinPPBorPPM.
TheIREDhasalargedisplayindicatingconcentrationandotherinstrumentfunctionssuchasbattery
chargeandperformance.Aninternalpumpprovidesrapidsamplingintothedetectionchamber.Audible
