日本GASTEC 二氧化氮檢測(cè)管9P
詳細(xì)介紹
二氧化氮檢測(cè)管NO.9P
二氧化氮檢測(cè)管NO.9P,二氧化氮NO2檢測(cè)管NO.9P,GASTEC二氧化氮NO2檢測(cè)管NO.9P氣體檢測(cè)管,GASTEC二氧化氮NO2檢測(cè)管NO.9P電泵用氣體檢測(cè)管檢測(cè)范圍0.02-0.2ppm。
GASTEC為了滿足用戶在氣體檢測(cè)方面的需要,而開(kāi)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(kāi)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)。
