| Abstract: | Improving an optical methane detector can make it has the functions of giving alarm and digital display. It can detect 0-10% methane with the certainty of 0.02%CH_4. It overcomes the defects of usual digital methane detectors, like a sesing elements being poisoned and losing efficacy, and the range of concentration of measurement being narrow. 3figs., 1ref. |
