二氧化碳NO.2AG的详细介绍二氧化碳NO.2AG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。CarbondioxideNo.2AgCO2PerformanceMeasuringRange200to3000ppmSamplingRate100mL/min(150mL)CorrectionFactor1SamplingTime1.5minutesDetectingLimitColorChangePaleblue→PurpleReactionPrincipleCO2+N2H4→NH2NHCOOHCoefficientofVariation10%(for200to1000ppm),5%(for1000to3000ppm)ShelfLife3YearsCorrectionsfortemperatureUnnecessaryfor0to40CorrectionsforhumidityUnnecessaryforR.H.0to90%Storethetubesatcoolanddarkplace.Possiblecoexistingsubstancesandtheirinterferences(NOTE)SubstanceConcentrationInterferenceChangecolorbyitself--------------------OthersubstancemeasurablewiththisdetectortubeCalibrationgasgenerationHighpressuregascylindermethodTLV-TWATLV-STELExplosiverange5000ppm30000ppm-)
