Seeking assistance regarding automatic oxygen content measurement instruments
Thread Content
Everyone, please help. During the start-up and shutdown replacement of methanol, it is necessary to measure the oxygen content, and an oxygen meter is intended to be used for this purpose. Provide information such as the type of instruments, prices, manufacturers, etc. This post was last edited by lifanwang on 2009-3-18 09:37.]
If a chromatograph is available, it can also be used for measurement; just fill a column. I don’t know the level of oxygen content; we use gas chromatography to test the oxygen in exhaust gases in our daily work. I’ve never seen the oxygen meter you mentioned; I can only provide you with the chromatograph. :)
Methanol is treated with oxygen, usually at a high purity. It is usually high-purity oxygen from a separation unit. In the past, instruments used to measure oxygen were typically thermal conductivity and thermomagnetic oxygen analyzers. Online detection. These days, such devices basically use magnetic mechanical and magnetic pressure oxygen analyzers. There are many domestic and foreign manufacturers that produce such instruments. I haven’t used any domestic ones; abroad, there are Shifumei 4100, Siemens 6E, ABB, and so on. The general price is around 130,000 to 170,000. Siemens is cheaper.
TELEDYNE’s electrochemical oxygen meters are excellent; the 3020T model is suitable for measuring trace amounts of oxygen, while the 3020P model is used for measuring percentages
