光明理化氫氣H2氣體檢測管137U
光明理化氫氣H2氣體檢測管137U ,氫氣H2氣體檢測管137U HYDROGEN 0.05-0.8%,日本光明理化工業(yè)株式會社從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 。
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

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.
