The life span of molybdenum wire
If the molybdenum wire can be usually used, and it can correctly learn to clean, then, how long is the life span of molybdenum wire after being used for a long time? Let’s learn how to maintain it in the following.
1. If it is found that the molybdenum wire is unresponsive, after calibration, it is obvious to drift, because the electrode head is contaminated, it is available to use cotton wool dipping a little alcohol to gently wipe the electrode head, the water and dust can be ruled out.
2. The appearance of the head of molybdenum wire has a layer of breathable film, do not touch or touch with hard objects.
See if the molybdenum wire is normal. Check the following method:
The air is steady for 30 minutes, and the 79 shift is less than 0.3, the molybdenum wire is normal.
Adding pure nitrogen or pure argon, readings should be greater than 99.98, the oxygen electrode should be changed if the requirement can not be met.
The molybdenum wire adopts a corrosion resistant oxygen electrode as a sensor. This instrument is mainly used for pressure swing adsorption nitrogen making machine, nitrogen gas cylinder, nitrogen generator, nitrogen purification device, and other occasions that need to analyze the concentration of nitrogen.
