A digital portable density meter is a handheld instrument used to measure the density of liquids and gases. It is commonly used in industries such as food and beverage, pharmaceuticals, and chemical manufacturing to ensure product quality and consistency.
The density meter works by measuring the buoyancy force on a submerged object, such as a small sphere, and then calculating the density of the fluid based on the mass and volume of the sphere. This method is known as the oscillating U-tube principle.
Digital portable density meters typically have a range of measurement capabilities, from low-density liquids such as oils and alcohols, to high-density liquids such as acids and detergents. They may also be able to measure the density of gases, although this may require additional equipment and calibration.
In addition to density measurement, some digital portable density meters may also have additional features such as temperature measurement and automatic calculation of other parameters such as specific gravity and concentration.
The portability of the density meter allows for on-site measurements and the ability to quickly verify the density of a sample, without having to transport the sample to a laboratory. This can save time and reduce the risk of contamination or sample degradation.
