Moisture meter is a measuring instrument used to measure the moisture content of various substances such as solids, granules, powders, colloids (slurry), liquids and gases. Moisture measurement of non-conductive substances such as tobacco, cotton, paper, construction, soil, etc. We all know that no matter what instrument is used, there are more or less errors, but how to reduce the error of the moisture meter during work? Here we will teach you how to solve the error.
1. The correct operation method of the moisture meter can reduce the measurement error. Before measuring the moisture meter, first read its instruction manual in detail, and then start to measure after understanding the basic positive solution operation method to reduce the error. The wrong operation method will increase the error during the use of the instrument.
2. When using a moisture meter to test the moisture content in a solid sample, if the measurement error is within the normal range, the suspicion of the accuracy of the instrument can basically be ruled out.
3. For the errors in the process of sample testing by the user using the moisture meter, in addition to the moisture contained in the sample itself, there should also be other volatile solvents. The working principle of the moisture measuring instrument is the heating weight loss method, that is, the moisture contained in the sample is reduced by the heating of the instrument, and then the moisture content of the sample is calculated according to the calculation function of the balance.
4. If there are other volatile solvents in the sample, in the process of heating the sample, we will not only volatilize the water contained in the sample, but also volatilize the solvent contained in the sample. In this way, in the process of testing, the error of the measurement value of the moisture meter will be reduced to ziu small.
Errors in the measurement of the moisture meter are escaping from disaster. As long as we do our best to use and operate correctly, we can reduce the error to ziu as much as possible, which is beneficial to our work.
