二甲醚CH3OCH3氣體檢測管123S DIMETHYL ETHER 0.01-1.2%

簡(jiǎn)要描述:

Japan KITAGAWA Gas Detector Tube System,123S DIMETHYL ETHER CH3OCH3 Dimethyl ether 二甲醚 0.01-1.2%,二甲醚CH3OCH3氣體檢測管123S DIMETHYL ETHER 0.01-1.2%,當用氣體檢測管檢測氣體時(shí)存在干擾氣體的判斷方法,檢測管的設計基本是單一目標氣體與檢測劑/反應劑/指示劑發(fā)生化學(xué)反應,從而顯示一定的顏色。所以當被測環(huán)境中有其他氣體共存時(shí),就有可能對結果產(chǎn)生干擾。
