氧气O2气体检知管159SB 的详细介绍
氧气O2气体检知管159SB
氧气O2气体检知管159SB ,氧气O2气体检知管159SB OXYGEN 2-24%,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 。

Hydrogen sulphide 2% Higher readings are given.
Nitrogen dioxide 2% 〃
Sulphur dioxide Similar stain is produced. 2% 〃
Carbon dioxide 〃5% 〃
6.NOTE
1)Coexistence of more than 5%of Carbon dioxide(CO2)gives higher reading and the reading from the scale
should be corrected with the following correction table.
2)The No.159SA and SB tubes are necessary to heat the part of the temperature indicator until the indicator
discolours from Red to Purple first. In case of No.159SA , it is necessary to use direct flame such as a match
or lighter to heat it up a non-hazardous area.No.159SB consists of a thin aluminum belt rolled on the indicator
and chemical liquid in a small bottle. When the liquid is dropped on the aluminum fully, a chemical reaction
occurs with generating smoke and temperature comes high. There, the No.159SB is possible to use in a
hazardous area.
