四氯乙烯Cl2C=CCl2氣體檢測(cè)管135SA TETRACHLOROETHYLENE 5-300ppm,中文名稱2: 全氯乙烯,英文名稱2: perchloroethylene,健康危害: 本品有刺激和麻醉作用。吸入急性中毒者有上呼吸道刺激癥狀、流淚、流涎。隨之出現(xiàn)頭暈、頭痛、惡心、運(yùn)動(dòng)失調(diào)及酒醉樣癥狀。口服后出現(xiàn)頭暈、頭痛、倦睡、惡心、嘔吐、腹痛、視力模糊、四肢麻木,甚至出現(xiàn)興奮不安、抽搐乃至昏迷,可致死。慢性影響:有乏力、眩暈、惡心、酩酊感等。可有肝損害。皮膚反復(fù)接觸,可致皮炎和濕疹。

四氯乙烯Cl2C=CCl2氣體檢測(cè)管135SA TETRACHLOROETHYLENE 5-300ppm

1. PERFORMANCE
1) Measuring range :10-300 ppm 5-150 ppm
Number of pump strokes 1/2(50ml) 1(100ml)
2) Sampling time :2 minutes/1 pump stroke
3) Detectable limit :1 ppm(100ml)
4) Shelf life :2 years(Necessary to store in a refrigerated place ; 0~10℃)
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 :Yellow→Red
2. RELATIVE STANDARD DEVIATION
RSD-low:10% RSD-mid.:10% RSD-high:10%
3. CHEMICAL REACTION
By decomposing with an Oxidizer, Hydrogen chloride is produced and PH indicator is discoloured.
CCI2=CCI2+PbO2+H2SO4→HCI
