How To Save The Oxygen Detector:
The first can be sealed in a sealed plastic package filled with nitrogen. Simple method of preservation is placed in the refrigerator freezer, while ensuring relatively dry air humidity. The second sensor itself is a consumable, and when it comes into contact with the air, it begins to react chemically. Therefore, the surface of the oxygen sensor is broken it is actually depleted, when your oxygen meter began to show data are not allowed, the combustion process shows the instability of oxygen and other issues, the basic is the oxygen sensor to replace the problem. Note:
1. You can pinch the inspiratory tube under normal pressure
2. You can adjust the flux between200 and 800ml/min, or put the tube into the water, it can produce 4 -6 bubbles.
