The principle of the densimeter is based on Archimedes principle F floating= ρ The liquid gV displacement indicates that the higher the density of the liquid, the smaller the volume of liquid discharged by the densitometer. By utilizing the floating and sinking conditions of the object, the density meter was floated in the liquid. According to the floating and sinking conditions of the object, F floats=G object, and the gravity of the object remains unchanged, so the buoyancy remains unchanged.
The densitometer used in physical experiments is an instrument for measuring the density of liquids. It is manufactured and operated based on the principle that the buoyancy of an object floating in a liquid is equal to gravity. The densitometer is a sealed glass tube with uneven thickness, and the lower part of the tube is filled with a small amount of high-density lead shot or mercury. When used, the densitometer is vertically placed in the liquid to be measured, and the densitometer is leveled
After stabilization, read the density of the liquid to be measured from its scale. There are two commonly used density meters: one is to measure the density of a liquid with a density greater than pure water, called a weight meter; Another type of liquid with a density smaller than pure water is called a light gauge
Usage of density meter:
Measurement steps:
① Place the product on the measuring table, display the weight of the product, and press the ENTER key to remember.
② Place the product in water to display the density value.
Density meters are suitable for various industries, and with the continuous progress of technology, the measurement level of density meters is also constantly improving. Measurement is not allowed, and the entire process should not be measured in one minute.
