The reason for the error of the zirconia oxygen analyzer: 1. Leakage. The zirconia oxygen analyzer must be strictly leak tested before it is first used. Oxygen micro-oxygen analyzers can only obtain accurate data results without rigor. Any connection points, solder joints, valves, etc. are not tight, which will cause oxygen in the air to reverse osmosis into the pipeline and inside the oxygen analyzer.
The reason for the error in the zirconia oxygen analyzer:
1. Leakage. The zirconia oxygen analyzer must be strictly leak tested before it is first used. Oxygen micro-oxygen analyzers can only obtain accurate data results without rigor. Any connection points, solder joints, valves, etc. are not tight, which will cause oxygen in the air to reverse osmosis into the pipeline and the inside of the oxygen analyzer, resulting in high oxygen content.
2. Pollution. When reusing the zirconia oxygen analyzer, first pay attention to whether air is leaking when connecting the sampling line of the oxygen analyzer, and the air leaking into the oxygen micro-analyzer must be carefully blown out, so as not to make a large amount. Oxygen passes through the sensor of the oxygen micro-oxygen analyzer to extend sensor life. In the pipeline system purification process, in order to shorten the purification time, it is necessary to have a certain method, generally using high pressure venting and small flow blowing alternately to rapidly purify the oxygen micro oxygen analyzer pipeline
3. Selection of pipe material. The material and surface roughness of the oxygen micro-oxygen analyzer will also affect the change of oxygen content in the sample gas. It is generally not advisable to use plastic pipes, rubber pipes, etc. as connecting pipes. Oxygen micro-oxygen analyzers are usually made of copper tube or stainless steel "target=_blank> stainless steel tube for ultra-micro analysis (referred to as stainless steel "target=_blank> stainless steel tube.
4. Simplification and cleanliness of the pneumatic system. The micro-analysis of the zirconia oxygen analyzer requires effective elimination of contamination of the sample gas by various dead ends in the valve, valve, meter, etc. on the gas path. Therefore, the oxygen micro-oxygen analyzer gas path system should be simplified as much as possible, and a connector with a small dead angle should be selected. Moreover, avoid using water seals, oil seals and wax seals to prevent the dissolved oxygen from escaping and causing pollution. It is also necessary to avoid the addition of purification equipment that is easy to cause pollution on the pipeline leading to the inlet of the oxygen micro-analyzer. Only in this way can the system be clean and the data obtained accurate.

Plastic packers are suitable for alignment when fixing slats, window frames, panels and floors on all irregular surfaces. They are very accurate and more cost-effective than hand cut cardboard, plywood, etc. Plastic packers of different thickness have different colors. This is a color coded size for easy identification. There are many sizes for you to choose from.
