Moisture change a great impact on the various properties of paper, with changes in moisture, which is quantitative, tensile strength, flexibility, folding and so will change, a4 paper size expansion will occur, or even curling, Alice, wrinkling, lotus leaf and so on. a4 paper moisture tester can measure not only a4 paper, waste water, and can measure solids, liquids, food, chemical, dried fruit, grain, plastics, rubber, wood, soil, floor, medicine, textiles, can be detected, in addition to products containing volatile substances can not be detected, other products can be detected very versatile, is the first choice of customers. a4 paper moisture tester, best a4 paper hygrometer introduction of foreign advanced technology uses high-frequency principle, that is, the instrument features a natural frequency, different analytes moisture pass through into the frequency of the sensor inside the machine is different, comparison of the two frequencies poor frequency current through the converter into a current, and then converted to a digital display through the ADC. Note 1, the body was kept in parallel with the measurement, the instrument shall be all three sensors Gently press in a4 paper, cardboard measuring above. 2, a4 paper cartons to be superimposed to the thickness of 50mm or more, so as to achieve best results.
