Background

Currently, solid density is an important physical property of a material, being the mass of a certain solid substance per unit volume. There are many methods of measuring the density of a material, but the most common and effective method is the archimedes drain method (density is calculated by mass and volume measurements): the solid sample testing method is that the test sample is put into the auxiliary liquid, when the test sample is completely immersed, the weight of the drained liquid is the buoyancy force of the test sample in the liquid, and the density of the solid sample can be obtained according to a corresponding formula; the liquid sample is put into the liquid to be tested by using the auxiliary solid sample, the method is consistent with the solid sample test, and the density of the liquid sample can be obtained according to a corresponding formula. The method has high precision, short measurement time and small accidental error, and the principle is widely used for detecting the density of the sample. The common density measuring device of the method is an instrument formed by combining an electronic balance, density software, density accessories and the like, and the electronic balance or a retransmission sensor is usually adopted for measuring.

However, different brands, different electronic scales, and load cells all require that a particular density accessory be customized to fit the respective electronic scale and load cell. The corresponding density fitting lacks universality, the actual condition of a balance does not need to be considered when a specific density fitting is customized, and different density test fittings are required to be used for solid samples with density higher than that of the auxiliary liquid or solid samples with density lower than that of the auxiliary sample, so that the operation process is complicated, and the accuracy of the experimental result is finally influenced.
