氮氧化物检测管NO.11A的详细介绍氮氧化物检测管NO.11A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。NitrogenoxidesNo.11ANO+NO2PerformanceMeasuringRange0.02to0.7ppm0.06to2ppmSamplingRate100mL/min(500mL)100mL/min(200mL)CorrectionFactor12.9SamplingTime5minutes2minutesDetectingLimitColorChangeWhite→BluishgreenReactionPrincipleABTS+NO2→BluishgreenproductCoefficientofVariation10%(for0.02to0.2ppm),5%(for0.2to0.7ppm)ShelfLife3YearsCorrectionsfortemperatureUnnecessaryfor0to40CorrectionsforhumidityUnnecessaryforR.H.0to90%Storethetubesatcoolanddarkplace.Possiblecoexistingsubstancesandtheirinterferences(NOTE)SubstanceConcentrationInterferenceChangecolorbyitself--------------------OthersubstancemeasurablewiththisdetectortubeCalibrationgasgenerationPermeationtubemethodTLV-TWATLV-STELExplosiverangeNO2:3ppmNO:25ppmNO2:5ppm-)
