日本北川式總烴氣體檢測管187S
日本北川式總烴氣體檢測管187S,總烴氣體檢測管187S GENERAL HYDROCARBONS 50-1400ppm,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 。

6) Temperature compensation :Necessary(refer to "Table 2. Temperature CorrectionTable")
7) Reading :Direct reading from the scale calibrated by 1 pump stroke
8) Colour change :Orange→Yellowish green
2. RELATIVE STANDARD DEVIATION
RSD-low:10% RSD-mid.:5% RSD-high:5%(Controlled on n-Hexane)
3. CHEMICAL REACTION

Substance Interference Coexistence
The bottom of the discoloured
Aromatic hydrocarbons layer is changed to Black and
higher readings are given.
It has no influence on readings even if Alcohols, Esters or Ketones each co-exists up to 6%.
(NOTE)
1)Determine the concentration of objective gas by multiplication with the figure shown in Table 1 after
temperature correction.
Example)For measuring Heptane at 10℃ of temperature
Reading concentration :600 ppm
Concentration on temperature correction :660 ppm
Concentration of Heptane :990 ppm
