Is there a 0 or lower scale on the measuring cylinder of the austenitic gas analyzer?

Answer:

The advantages of austenitic gas analyzer are simple structure, low cost and easy maintenance.The main problems in the practical application of austenite gas analyzer are:1) this method is manual analyzer, the operation is more cumbersome, low precision, slow speed, can not achieve online analysis, can not adapt to the needs of production development;2) the volume of the comb tube has an influence on the analysis result, especially the impact on the explosion method;3) hot analysis determination time length Austria instrument, place has some limitations, but also must pay attention to the degree of chemical reaction, reading or not mislead the production;

Working principle of austenite gas analyzerThe use of different solutions to different groups have been absorbed in the gas sample points in the sample of carbon dioxide with 40% sodium hydroxide absorption; in the sample of oxygen by pyrogallol solution of potassium absorption; using ammonia solution to absorb cuprous chloride in the sample of carbon monoxide. Then the content of each component is calculated according to the volume change of the sample before and after the absorption. CH4 and H2 were determined by explosive combustion, and the remaining gas was N2.
