Don't get me wrong, the water tester can detect all the problems in the water, not the machine. The machine still needs machine testing. Similarly, what quality engineers do is irreplaceable by machines. The work of water testers is mainly divided into smell and routine. They will collect water samples first? Smell? See if there's any smell. There seems to be something that needs heating to smell again. What is the second step? Smell? See who has a strange smell. Unless it is obvious that water is water in the eyes of ordinary people. Where is the smell?
This job looks simple, but it's tiring. How can people who don't work hard and are not responsible notice the slight difference in the water? This job is very strict with the quality engineer himself, and can even be described as harsh. They first need a keen sense of smell, no rhinitis and other diseases, and even have certain requirements for vision. Secondly, they can't touch anything with strong smell when on duty, let alone wear perfume for beauty. Moreover, in daily life, they can't touch food that stimulates the taste, even eating garlic. Such conditions are too harsh for ordinary people to do.
They just make money with their tongues and noses, so they have to take extra care of these two organs. In today's increasingly tense water resources, their existence, like environmental police, ensures people's drinking water safety. Although their occupations are relatively small, they are very important to the public. We should understand them, respect them and cooperate with their work.
