TW-300A rubber densitometer

Rubber densitometer,Plastic densitometer,densimeter,hydrometer,TW-300AThe difference between a density meter and a specific gravity meter:

Many customers often ask a question: What is the difference between density and specific gravity? So I wrote down the definitions of density and specific gravity.

density(density)It refers to the weight per unit volume of a substance.

D＝W/Vthat isD＝Wa/(Wa－Ww)Usually ing/cm3express.

WaThe weight of the sample in air.WwThe weight of the sample in water.

Definition of specific gravity

1The density of materials and4Density ratio of pure water at ℃SG=material density/4℃Pure water density 2The ratio of the weight of an object in air to its volume.

Example: If the weight of an object in air isPKe, object in water4The weight at ℃ isP1gramThen SG=P/(P-P1)

For liquids or solids, it refers to the density at a specific temperature and pressure, as well as the standard value of pure water

Maximum density under air pressure (temperature)3.98The density at ℃ is999.972kg/m3）The ratio of

For gas, it refers to the molecular weight of gas and the molecular weight of air(28.9644)The ratio.

The specific gravity generally varies with temperature and pressure. Specific gravity abbreviated asSG.

In general, we value density and ratio as the same concept, so our density tester can also be called a density balance,Specific gravity balance,densimeter,Specific gravity meter, etc

The definition of density is the mass per unit volume, and density has units. The definition of specific gravity is the mass of a substance at a certain temperature4The ratio of the mass of stagnant water in the same body at Celsius degrees (therefore called specific gravity, mass commonly known as "weight"), it is obvious that specific gravity has no unit. Therefore, the physical meanings of the two are completely different, but4The density of water in Celsius is almost very accurate1g/cm3Therefore, when the density is usedg/cm3Or equivalentkg/dm3When using equivalent units, the values of the two are the same (when using other non equivalent units, the values are also different).
