Principle of the densitometer According to Archimedes' principle F float = ρ liquid gV discharge, the greater the density of the liquid, the smaller the volume of liquid that the densitometer displaces.
Float the density meter in the liquid using the object's float and sink conditions. According to the object's floating and sinking conditions, it can be stated that F float = G object when floating, and the object's gravity remains unchanged, so the buoyancy does not change.
A densitometer, used in physics experiments, is an instrument used to measure the density of liquids.
It is manufactured and operated on the principle that the buoyancy of the object floating in the liquid is equal to the force of gravity. The density meter is a sealed glass tube of non-uniform thickness. The bottom of the tube is marked with a small Mfitted with dense lead shot or mercury.
Put the density meter vertically into the liquid to be tested, and read the density of the liquid to be tested from the scale after the density meter is stable.
There are two types of density gauges commonly used: one is called a heavy gauge, which measures the density of a liquid whose density is greater than that of pure water, and the another is called a heavy gauge a light meter that measures the density of a liquid less than that of pure water.
How to use the density meter:
Measurement steps:
①Put the product in the measuring table , product weight display, press the ENTER button to save.
②Put the product in water to display the density value.
The density meter is suitable for all areas of life. At the same time mWith the continuous development of technology, the measurement level of the density meter is also continuously improved. This is not allowed to measure accurately, and the whole measuring process does not take 1 minute.
