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

簡要描述:

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(dāng)用氣體檢測管檢測氣體時存在干擾氣體的判斷方法,檢測管的設(shè)計基本是單一目標(biāo)氣體與檢測劑/反應(yīng)劑/指示劑發(fā)生化學(xué)反應(yīng),從而顯示一定的顏色。所以當(dāng)被測環(huán)境中有其他氣體共存時,就有可能對結(jié)果產(chǎn)生干擾。
