四氯化碳CCl4气体检测管147S
四氯化碳CCl4气体检测管147S，四氯化碳CCl4气体检测管147S CARBON TETRACHLORIDE 5-60ppm，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 。
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.
