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

Permeation tube method

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.
