ELECTRICAL GAS ANALYSER FOR SENSING AT LEAST TWO GASES |
摘要 |
A portable gas analyzer uses a pump to take a gas sample and pump it through a carbon monoxide sensing cell, an oxygen-sensing cell and a methane-sensing pellister. Concentrations of these gases are displayed continuously on LCD displays. The gas analyzer is particularly useful in underground coal mines and offers the possibility of replacing many different gas analyzers with a simple convenient apparatus which gives continuous readings of all the critical gas concentrations. |
