丙酮?dú)怏w檢測(cè)管102SA 

丙酮?dú)怏w檢測(cè)管102SA ，丙酮?dú)怏w檢測(cè)管102SA ACETONE CH3COCH3 0.1-5.0%，日本光明理化工業(yè)株式會(huì)社從1947年開始，在氣體分析領(lǐng)域開拓了六十余年 , 形成了于世的 ” 北川 ” 式氣體檢測(cè)管。氣體快速分析法 ” 北川 ” 的歷史就是日本檢測(cè)管的歷史 。目前是世界上zui大的檢測(cè)管生產(chǎn)廠家，也是日本*家通過美國(guó)SEI的認(rèn)證，歐盟的認(rèn)證的檢測(cè)管廠家。公司不僅有ISO9001:2000的認(rèn)證，還獲得了環(huán)境管理的ISO14001的認(rèn)證。北川式手動(dòng)氣體采集器AP-20 備有采氣完成指示計(jì) , 可以清楚的判明采氣是否完成 . • 有專門截留玻璃的截留槽 , 以防止檢測(cè)管割尖時(shí)玻璃片飛濺 . • 有采氣容積為 50 毫升和 100 毫升的兩段式制動(dòng)卡 . • 采氣器極為小巧 , 并有便于攜帶的皮具包 。

*Methanol is indicated with half the sensitivity and Ethyl acetate has the same sensitivity with Acetone.
(NOTE)
1) If the discolouration is over the scale, replace the tube with new one and pull the handle at half stroke(to 50mr
line). And read a figure from the scale on the tube.
2) Correct the reading value with theTEMPERATURE CORRECTION TABLE first . and convert the value into an
actual concentration by uing the conversion scale shown in the instruction sheet.
