Do You Know the Principle of Electronic Density Balance and Preparation before Measurement?

       Have you ever learned about principles and preparations before measurement? As a professional Electronic Equipment Factory, today let me introduce it to you.

       First, let's take a brief look at the principle of Electronic Density Balance:

       1. The density of an object is its ratio of mass to volume.

　　2. Density measurement is based on the Archimedes principle.

　　3. Solid density measurement usually uses a liquid of known density (such as , water or ethanol) as an auxiliary liquid, which can be calculated by weighing the solids to be tested successively in air (A) and auxiliary liquid (B). Find its density.

Electronic Density Balance

　　Before performing Electronic Density Balance measurements, we need to do the following preparations:

　　1. Electronic balance.

　　The accuracy of the electronic balance should be selected according to the specific requirements of the accuracy of the measured density data, and the capacity of the electronic balance should be selected according to the volume and weight of the sample to be tested. Before the test, it is necessary to preheat the prepared Electronic Density Balance for a long time and make necessary corrections to ensure the accuracy of the measurement data.

　　2. Test the components.

　　It is necessary to select a suitable test component. For example, for some materials that are large in size and cannot be placed in the weighing chamber, the under-hook test component should be selected.

　　3. Sample to be tested.

　　In order to measure the accuracy of the density in consideration of the influence of the surface tension of water, it is recommended that the weight of the sample to be measured should be greater than 1g. In order to improve the measurement accuracy, it is recommended to select a sample with a shape rule and a small surface roughness.

　　4. Select the appropriate auxiliary liquid.

　　Generally available: water, alcohol and others.
