一氧化碳检测管1A的详细介绍一氧化碳检测管1A快速检测管是一种现场快速、直读测定气体浓度的检测手段，由一支内装显色指示剂、外壁印有浓度刻度的玻璃管组成，当被测气体通过管内指示剂时发生显色化学反应，测试人便可通过变色界线直接读出气体的浓度。具有数百种气体和不同的浓度范围，欢迎来电咨询。CarbonmonoxideNo.1ACOPerformanceMeasuringRange5to50ppmSamplingRate100mL/min(300mL)CorrectionFactor1SamplingTime3minutesDetectingLimitColorChangeYellow→DarkbrownReactionPrincipleCO+Na2Pd(SO3)2→Pd+CO2+SO2+Na2SO3CoefficientofVariation10%(for5to10ppm),5%(for10to50ppm)ShelfLife3YearsCorrectionsfortemperatureUnnecessaryfor0to40CorrectionsforhumidityUnnecessaryforR.H.0to90%Possiblecoexistingsubstancesandtheirinterferences(NOTE)SubstanceConcentrationInterferenceChangecolorbyitselfOthersubstancemeasurablewiththisdetectortubeCalibrationgasgenerationHighpressuregascylindermethodTLV-TWATLV-STELExplosiverange25ppm-12.5to74%)
