日本北川式汞蒸氣Hg氣體檢測管142S
日本北川式汞蒸氣Hg氣體檢測管142S,汞蒸氣Hg氣體檢測管142S MERCURY VAPOUR 0.1-10mg/m3,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(rèn)證,歐盟的認(rèn)證的檢測管廠家。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 。
