乙苯檢測(cè)管NO. 122P的詳細(xì)介紹
乙苯檢測(cè)管NO. 122P
乙苯檢測(cè)管****22P,GASTE乙苯C6H5C2H5 NO. 122P氣體檢測(cè)管,乙苯檢測(cè)管NO. 122P電泵用氣體檢測(cè)管檢測(cè)范圍110-2750μg/m3。
GASTEC為了滿足用戶在氣體檢測(cè)方面的需要,而開發(fā)出了電子自動(dòng)采氣泵。用傳統(tǒng)的電子吸氣泵幾乎不能進(jìn)行有效的采氣,因?yàn)闄z測(cè)管里的填充試劑密度很高。而GASTEC開發(fā)的GSP電泵系列能提供強(qiáng)勁吸力,能滿足特定的檢測(cè)管的取樣要求。電泵和檢測(cè)管組成的新的檢測(cè)系統(tǒng)能適用于作業(yè)環(huán)境的檢測(cè)。

Miscellaneous
Electric sampling pump This detector tube is suited for measuring toluene in indoor environments. The GSP-200 / GSP-300FT-2 series automatic gas samplers (or comparable sampling devices/pumps) should always be used for optimal performance. A deviation of +/-10% in the sampling flowrate (i.e. amount of air flowing through the tube at a given moment) or the sampling amount (total sampled amount of target substance) causes an average margin of error of approx. +/-10% (maximum +/-20%) in the indicated value. |
