A portable density meter, often known as a digital hydrometer, oscillates a U-shaped hollow glass tube to measure density digitally while automatically compensating for temperature. Various industries, including chemical, food, beverage, and more, can use this instrument in the lab or out in the field as well. In addition to this, the said product is also used to gauge a liquid or gas sample's density. Pharmaceutical, petroleum, chemical, and food and beverage industries all employ portable density meters for quality control and R&D. The manufacturer can inspect finished items, semi-finished products, and raw materials using density measurements.
