The source of cobalt for making carbon monoxide detectors
In the past, if you want to make a carbon monoxide detector, it must be in the source of cobalt. The source of cobalt is the core of the detector, and the job of the sensing department is related to precision and sensitivity, so it is an important task.

At the beginning, gather all materials and visit all capable workers. Cobalt sources are rare, and its nature is special. It is difficult to mine and it is also difficult to control. However, everyone is determined, and they are not afraid of obstacles.

Looking for ore sources, deep in the mountains, through the forest, through the cold and summer. Exploring ore seedlings, and researching the method of refining. The craftsmen study day and night, try all kinds of methods, adjust all kinds of ginseng, and after a hundred times and a thousand tests, they

Then refine the cobalt source, grind its quality, adjust its properties, so that it can sense carbon monoxide accurately. In the dark room, put all the gas, test the reaction of the cobalt source, whether sensitive or blunt, carefully observe and memorize, and repeatedly adjust.

Finally, the cobalt source is formed. Installed in the detector, try it on the ground, and sense carbon monoxide, that is, a warning is issued, accurate and sensitive, and everyone is happy. The work of this cobalt source is also the fruit of everyone's hard work. In the future, based on this, I hope to improve the skills of the detector to ensure everyone's well-being and protect the environment.
