Traditional moisture measurement replaced by moisture meter
In the history of instrumentation development, mankind in the traditional handmade instruments to modern scientific instruments continue to explore. And for the object moisture measurement method is also constantly improving, early as if there is no moisture meter this statement. At the beginning of the moisture measurement is through the drying method and then according to the weightlessness method of the formula: [moisture content = [weightlessness of the object before the mass of the object - weightlessness of the object after the mass of the object) / weightlessness of the object before the mass of the water content of the manual calculation, this method of calculation of the moisture content is very inaccurate and the results of the measurement is susceptible to a variety of factors, resulting in the measurement of the data is not stable.
Driven by industrial technological innovation, after the mid-20th century, with the emergence of automatic control theory and the maturity of automatic control technology, the rapid development of digital moisture tester based on A/D (digital / analogue conversion) link. Accompanied by computers, communications, software, new materials and new technologies, the rapid development and maturity of artificial intelligence and online measurement becomes possible, so that the moisture measuring instrument towards intelligence, digitalisation and automation. Moisture meter in recent years can be found everywhere, in a variety of industries have been widely used, the traditional measurement error of the moisture meter and moisture measurement methods are slowly being eliminated.
Moisture meter can be widely used in all the need for rapid determination of moisture in the industry, such as medicine, food, feed, seeds, rapeseed, dehydrated vegetables, tobacco, chemical, tea, food, meat and textile, agriculture and forestry, papermaking, rubber, plastics, textiles and other industries in the laboratory and the production process, and at the same time to meet the solids, particles, powders, gels, and liquids in the determination of the water content of the requirements.
In the use of moisture meter, we need to pay attention to the results of the titration of moisture meter can be in accordance with certain requirements of the format of input and output, and moisture meter can automatically carry out the relevant statistics and analysis, so that our moisture meter can get the relevant data in a timely manner, fast moisture meter in the use of not only to know its technical characteristics, but also a lot of things need to pay attention to, so the use of titration speed. So the titration speed should be fast and accurate when using.
Moisture meter should try to avoid direct sunlight, vibration and other situations, good also do not have the temperature of the interference and power fluctuations, around the instrument should leave enough space for heat dissipation, so as to avoid heat gathering to produce inaccurate measurements of the occurrence of the matter should be maintained with the instrument and the distance between the test material. In the process of using, should pay attention to the instrument's vent can not be covered, filled with other items, which is very dangerous, in the beginning of heating, can not put those flammable items around the instrument, so as not to cause harm to the operator. In addition, the weight of the sample of the substance to be measured should be as small as possible, which will help the accuracy of the test results.
