The oxygen analyzer is an oxygen analyzer that uses a zirconium oxide oxygen concentration difference battery as a detection sensor. The measurement and control system of this instrument adopts a new type of single-chip computer calculation and control system, LED display; it has the characteristics of advanced technology, high precision, fast response, stable performance, complete functions, convenient operation, continuous gas analysis process, etc.; it can not only measure residuals in the boiler combustion process Oxygen content can be used for thermodynamic research, continuous monitoring of oxygen content in gas manufacturing plants, control of soaking furnace combustion process, detection of oxygen content in gases in chemical, metallurgical, electronic industry, medical and other fields.
Oxygen analyzers can generally be divided into three categories according to different principles: fuel cell method oxygen analyzer, zirconia sensor of zirconia method, and magnetic oxygen analyzer. There are many precautions in the use of oxygen analyzer, otherwise it is very easy to have problems such as inaccurate analysis results.
Oxygen analyzer use and storage matters:
1. Do not open the case of the instrument during use to avoid the danger of burns and electric shock.
2. The instrument should avoid strong vibration during use, storage, and transportation to avoid damage to the zirconia sensor.
3. The instrument should be kept clean during storage. To prevent the instrument from getting wet, the inlet and exhaust nozzles should be covered with dust caps to prevent foreign objects and dust from falling into it.
4. When the instrument is used for the first time, the connection points, solder joints, valves, etc. should be tested for leaks to ensure that oxygen in the air will not reverse seep into the pipeline and the inside of the instrument, resulting in high measured values.
5. Purify the piping system when using the instrument again, blow out the leaked air, and make sure that no air leaks when connecting the sampling pipeline.
6. The change of oxygen content in the sample gas will be affected by the pipe material and surface roughness. Therefore, copper pipes or polished stainless steel pipes are generally used for connecting pipes instead of plastic pipes or rubber pipes.
7. In microanalysis, avoid the dead angles of various pipe fittings, valves, meters and so on from polluting the sample gas. Therefore, the gas path system must be simplified as much as possible, and the dead angles of the connecting parts should be small. In order to prevent pollution caused by the escape of dissolved oxygen, water seals, oil seals and wax seals can be used to ensure accurate data.
