1,1-二***CH2:CCl检测管132D
1,1-二***CH2:CCl检测管132D1,1-二***CH2:CCl检测管132D,GASTEC1,1-二***CH2:CCl检测管132D检测范围6-600ppm,检测管检测时间在1-10小时左右。1,1-二***CH2:CCl检测管132D采用自然扩散的方式。1,1-二***CH2:CCl检测管132D其特点:简洁,轻巧,方便多用、直接读数、不需取样设备。被动扩散式检测管是用来测定较长时间下气体浓度的时量平均值(TWA),采用自然扩散的方式。这种检测管里面填充有吸附剂及反应剂,气体以一定的速率被均匀吸附,从而出现较为明显均匀的变色检测工作场所人员的***气体暴露量时,用右图的检测管夹(710)放置在人员衣领处即可。检测***气体在工作场所的分布时,把该检测管固定放置一段时间后就可检测出来。也可用来进行更长时间的检测TrichloroethyleneNO.132DCl2C:CHClPerformanceMeasuringRange3to300ppmSamplingHours1to8hoursColourChangeYellow→PurpleReactionPrincipleCl2C:CHCl+PbO2+H2SO4→HClHCl+Base→ChlorideCoefficientofVariation10%(for25to300ppm-hr)ShelfLife1YearCorrecti***fortemperature&humidityTemperaturecorrectionisnecessaryStorethetubesintherefrigeratortokeepat10ºC(50ºF)orbelow.PossiblecoexistingsubstancesandtheirinterferencesSubstanceInterferenceChangecolourbyitselftoHydrogenchloride,Chlorine+Purple1,2-Dichloroethylene,Tetrachloroethylene+PurpleToluene,XyleneNoNoOthersubstancemeasurablewiththisdetectortubeSubstanceCorrectionFactorSamplingTimeMeasuringRangetrans-1,2-Dichloroethylene2.01to8hours6to600ppmChlorine0.81to8hours2.4to240ppmHydrogenchloride0.61to8hours1.8to180ppmTetrachloroethylene0.51to8hours1.5to150ppmCalibrationgasgenerationDiffusiontubemethodTLV-TWATLV-STELExplosiverange10ppm25ppm-GASTEC|GV-110S|GV-100S|手动气体***AP-20|北川式气体检测管|光明理化气体检测管|日本理化手动气体采样器|北川式气体***GASTEC日本气体快速检知管|便携式气味传感器|气味检测仪迷你型XP-329m|气味传感器XP-329ⅢR|恒流型自动气体采样器GSP-400FT|GASTEC气体采样器)
