Mechanical Balances and Scales are traditional weighing instruments that measure the mass of objects using springs, levers, or beam mechanisms without requiring electricity. The weight is indicated via a pointer on a dial or by balancing against known masses.
They are durable, simple to use, and require minimal maintenance, making them suitable for laboratories, industrial settings, retail, and educational purposes. Mechanical balances are ideal where robustness and reliability are more important than digital precision.
