Oxygen Analyzer Use Precautions
Oxygen analyzer is widely used in the continuous monitoring system of flue gas CEMS flue gas humidity measurement, can also be applied to wood, building materials, paper, chemical, pharmaceutical, fiber, textile, tobacco, vegetables, food processing humidity control; Can also be used in ceramic drying furnace, electrode drying furnace and other high temperature environment, humidity determination.
Oxygen analysis instruments in accordance with the principle of different, generally can be divided into three categories: fuel cell oxygen analyzer, zirconia zirconia sensor, magnetic oxygen analyzer. Oxygen analysis equipment in use there are many considerations, or prone to analysis results are not accurate and so on. So, Levin hundred network summary of the Notes, for your reference:
1, oxygen analyzer in the first opening, Oxygen Analyzer should be on the connection point, solder joints, valves and other leaks to ensure that the oxygen in the air will not reverse into the pipeline and the instrument inside, resulting in high measurement values.
2, before using the instrument again, to purify the pipeline system, the air will be blown away from the clean, while ensuring that the connection to the sampling pipeline did not leak into the air.
3, the sample gas oxygen content changes will be affected by the pipe material and surface roughness, so the general connection pipe selection of brass or polished stainless steel tube, rather than the use of plastic pipe, rubber tube and so on.
4, micro-analysis, to avoid all kinds of pipe fittings, valves, watches and other dead ends of the sample gas pollution, it is necessary to simplify the air system as much as possible, the connection dead ends. Oxygen Analyzer The power to prevent the dissolution of dissolved oxygen caused by pollution, it is best to use water seal, oil seal and wax seal and other equipment, in order to ensure accurate data.
