光明理化氢气H2气体检测管137U
光明理化氢气H2气体检测管137U ,氢气H2气体检测管137U HYDROGEN 0.05-0.8%,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 。
Tube No.137U
1. PERFORMANCE
1) Measuring range ：0.05-0.8％
Number of pump strokes 1/2(50ml)
2) Sampling time ：0.5minutes/1/2 pump stroke
3) Detectable limit ：0.03％
4) Shelf life ：3 years
5) Operating temperature ：0～40℃
6) Temperature compensation ：Necessary(See "TEMPERATURE CORRECTION TABLE")
7) Reading ：Direct reading from the scale calibrated by 1 /2 pump strokes
8) Colour change ：Yellow→Green
2. RELATIVE STANDARD DEVIATION
RSD-low：10％ RSD-mid.：10％ RSD-high：10％
3. CHEMICAL REACTION
By reacting with Oxygen in Atomsphere, water vapour is produced. This Water vapour reacts with Magnesium
perchlorate and PH indicator is discoloured.
H2＋O2→H2O
H2O＋Mg(CIO4)2→Mg(CIO4)2?H2O
4. CALIBRATION OF THE TUBE
STANDARD GAS CYLINDER METHOD
5. INTERFERENCE AND CROSS SENSITIVITY

Ethanol FIG.1 0.25 Similar stain is produced. 0.4％ Higher readings are given.
Carbon monoxide Tafhfeec atecdc.urate readings are not 500 Lower readings are given.
6.SPECIAL NOTE
1)The tube will not respond in the absence of oxygen.
2)When the concentration of Hydrogen is 12 to 16％, pretreat reagent gives a heat but is not dangerous for use
in hazardous area.
3)When the concentration of Hydrogen is over 40％, the reading value may be indicated below 0.8％.In this
case, the bottom of the discoloured layer becomes dark purple. In order to make sure that the concentration is
extremely high such as 40％, measure the gas concentration with connecting 2 tubes. If both tubes are
discoloured to green, extremely high concentration Hydrogen exists.
