光明理化乙硼烷B2H6气体检测管242S
光明理化乙硼烷B2H6气体检测管242S ，乙硼烷B2H6气体检测管242S DIBORANE 0.02-5ppm，日本光明理化工业株式会社从1947年开始，在气体分析领域开拓了六十余年 , 形成了驰名于世的 ” 北川 ” 式气体检测管。气体快速分析法 ” 北川 ” 的历史就是日本检测管的历史 。目前是世界上*大的检测管生产厂家，也是日本**家通过美国SEI的认证，欧盟的认证的检测管厂家。公司不仅有ISO9001:2000的认证，还获得了环境管理的ISO14001的认证。北川式手动气体采集器AP-20 备有采气完成指示计 , 可以清楚的判明采气是否完成 . • 有专门截留玻璃的截留槽 , 以防止检测管割尖时玻璃片飞溅 . • 有采气容积为 50 毫升和 100 毫升的两段式制动卡 . • 采气器极为小巧 , 并有便于携带的皮具包 。
1. PERFORMANCE
1) Measuring range ：0.1-5 ppm 0.05-2.5 ppm 0.02-1.0 ppm
Number of pump strokes 1(100ml) 2(200ml) 5(500ml)
2) Sampling time ：1 minute/1 pump stroke
3) Detectable limit ：0.01 ppm(500ml)
