Weighing scales are similar to balances however a balance determines mass by balancing an unknown mass against a known mass Balances are generally more sophisticated than scales and often used by professionals for advanced scientific weighing in laboratories universities medical facilities and research and development related environments
19 11 2019 In modern weighing machines balances are usually of the design that uses a force restoration mechanism to create a force to balance the force due to the unknown mass Balances are generally more sophisticated than scales and are used by professionals for advanced scientific weighing in science laboratories universities medical facilities and
Analytical balances usually include draught proof weighing chambers for precise measuring of mass and are often used alongside anti vibration tables to increase accuracy A precision balance on the other hand typically measures to the nearest 0 1 0 01g but has higher capacity Both can measure capacities from hundreds of grams to kilograms
