1,3-丁二烯氣體檢測管168SC
1,3-丁二烯氣體檢測管168SC，168SC 1,3-BUTADIENE 1,3-丁二烯氣體檢測管 1,3-Butadiene CH2=CHCH=CH2 2.5-100ppm,日本光明理化工業(yè)株式會社從1947年開始，在氣體分析領域開拓了六十余年 , 形成了馳名于世的 ” 北川 ” 式氣體檢測管。氣體快速分析法 ” 北川 ” 的歷史就是日本檢測管的歷史 。目前是世界上*大的檢測管生產(chǎn)廠家，也是日本**家通過美國SEI的認證，歐盟的認證的檢測管廠家。公司不僅有ISO9001:2000的認證，還獲得了環(huán)境管理的ISO14001的認證。北川式手動氣體采集器AP-20 備有采氣完成指示計 , 可以清楚的判明采氣是否完成 . • 有專門截留玻璃的截留槽 , 以防止檢測管割尖時玻璃片飛濺 . • 有采氣容積為 50 毫升和 100 毫升的兩段式制動卡 . • 采氣器極為小巧 , 并有便于攜帶的皮具包 。
