詳情介紹：
日本光明理化二丙酮醇氣體檢測管190U
日本光明理化二丙酮醇?xì)怏w檢測管190U，二丙酮醇?xì)怏w檢測管190U DIACETONE ALCOHOL 10-250ppm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 。
1. PERFORMANCE
1) Measuring range ：10-250 ppm
Number of pump strokes 3(300ml)
2) Sampling time ：4.5 minutes/3 pump strokes
3) Detectable limit ：1 ppm
4) Shelf life ：2 years
5) Operating temperature ：10～40℃
6) Temperature compensation ：Necessary(See "TEMPERATURE CORRECTION TABLE")
7) Reading ：Graduations printed on the tube are calibrated by Ethyl cellosolve at 3 pump strokes
and Diacetone alcohol concentration is determined by using a conversion chart.
8) Colour change ：Yellow→Pale blue
2. RELATIVE STANDARD DEVIATION
RSD-low：10％ RSD-mid.：5％ RSD-high：5％
