四氯化碳CCl4氣體檢測(cè)管147S
四氯化碳CCl4氣體檢測(cè)管147S，四氯化碳CCl4氣體檢測(cè)管147S CARBON TETRACHLORIDE 5-60ppm，日本光明理化工業(yè)株式會(huì)社從1947年開(kāi)始，在氣體分析領(lǐng)域開(kāi)拓了六十余年 , 形成了馳名于世的 ” 北川 ” 式氣體檢測(cè)管。氣體快速分析法 ” 北川 ” 的歷史就是日本檢測(cè)管的歷史 。目前是世界上*大的檢測(cè)管生產(chǎn)廠家，也是日本**家通過(guò)美國(guó)SEI的認(rèn)證，歐盟的認(rèn)證的檢測(cè)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(dòng)氣體采集器AP-20 備有采氣完成指示計(jì) , 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(cè)管割尖時(shí)玻璃片飛濺 . • 有采氣容積為 50 毫升和 100 毫升的兩段式制動(dòng)卡 . • 采氣器極為小巧 , 并有便于攜帶的皮具包 。
1. PERFORMANCE
1) Measuring range ：1-60 ppm 0.5-1 ppm
Number of pump strokes 1(100ml) 2(200ml)
2) Sampling time ：1.5 minutes/1 pump stroke
3) Detectable limit ：0.2 ppm(200mr)
4) Shelf life ：1 year
5) Operating temperature ：0～40℃
6) Temperature compensation ：Necessary(See "TEMPERATURE CORRECTION TABLE")
7) Reading ：Direct reading from the scale calibrated by 1 pump stroke
8) Colour change ：White→Red
2. RELATIVE STANDARD DEVIATION
RSD-low：15％ RSD-mid.：10％ RSD-high：10％
3. CHEMICAL REACTION
Carbon tetrachloride is decomposed and Phosgene is produced. By reacting with this Phosgene,
4- (p-Nitrobenzyl)-phridine and Benzylaniline, dyestuff is produced.

(NOTE)
When the concentration is below 1 ppm, 2 pump strokes can be used to determine the lower concentration.
Following formula is available for the actual concentration.
Actual concentration＝1/2×Temperature corrected value
6.CAUTION
When high concentration gas(over the full scale)is sampled, the indicator will be discoloured from pale yellow
to dark blue. If extremely high concentration gas is sampled, the detecting reagent may be faded and it is not
possible to distinguish with original colour.
