Dahongmeituo Gold Density Meter will be launched in February 2025! A gold densitometer is an instrument used to measure the density of gold or other precious metals. Density is the ratio of the mass to the volume of a substance, with gold having a higher density of approximately 19.32 g/cm ³. Therefore, measuring density can determine the purity or authenticity of gold.

Working principle of gold densitometer

1. Archimedes' principleThe gold densitometer is typically based on Archimedes' principle, which states that the buoyancy an object experiences in a liquid is equal to the weight of the liquid it displaced. By measuring the weight of gold in air and water, its volume and density can be calculated.

2. Measurement steps：

• Firstly, measure the weight of gold in the air (W ₁).

• Then immerse the gold in water and measure its weight (W ₂) in the water.

• Calculate density according to the formula:

  $$\text{density}=\frac{W_1}{W_1-W_2}\times {\rho }_{\text{water}}$$

  among which,${\rho }_{\text{water}}$It is the density of water (usually taken as 1 g/cm ³).

1. Precautions for using a gold densitometer

2. Clean the sampleEnsure that the surface of the gold is free of oil stains or impurities to avoid affecting the measurement results.

3. Water temperature controlThe density of water varies with temperature and is usually measured at a standard temperature (such as 20 ° C).

4. Bubble exclusionWhen immersed in water, it is necessary to ensure that there are no bubbles attached to the surface of the gold, otherwise it will affect the volume measurement.

Application scenarios

• Gold purity testingDetermine the purity of gold through density, such as 24K, 18K, etc.

• Authenticity identificationThe density of fake gold is usually lower than that of pure gold, and a densitometer can be used for rapid identification.

• Jewelry processingIn the process of jewelry production, density meters can be used for material testing and quality control.
