苯乙烯C6H5CH=CH2氣體檢測(cè)管158S
苯乙烯C6H5CH=CH2氣體檢測(cè)管158S ，苯乙烯C6H5CH=CH2氣體檢測(cè)管158S STYRENE 2.5-300ppm，日本光明理化工業(yè)株式會(huì)社從1947年開(kāi)始，在氣體分析領(lǐng)域開(kāi)拓了六十余年 , 形成了馳名于世的 ” 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*大的檢測(cè)管生產(chǎn)廠家，也是日本**家通過(guò)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(zhuān)門(mén)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 。
