A liquid density meter is an instrument used to measure the density or specific gravity of a liquid. Liquid specific gravity refers to the ratio between the density of a liquid and the density of water. Usually, physical principles such as buoyancy or vibration frequency are used to measure the density of liquids.
The MDY-2 liquid specific gravity meter is designed to measure liquid density, with a lifting platform and an optional constant temperature cup, making operation very convenient. The standard parts are 5 cubic centimeters of stainless steel, and standard volume parts with acid and alkali resistant platinum wire and glass body can also be selected.
Sensors that adopt the principle of electromagnetic force balance have high sensitivity, high precision, and high repeatability. It is convenient to choose a constant temperature cup, which can be used in conjunction with a constant temperature bath to accurately control the temperature of the tested sample.
