A mechanical counter is a device used to count objects or events through a mechanical mechanism. It typically consists of gears and levers that move in response to a specific action, such as pressing a button or passing an object. Each action increments the count displayed on a series of dials or digits. These counters are commonly found in various applications, including industrial machinery, sports, and laboratory experiments. Unlike electronic counters, mechanical counters do not require batteries or power sources, making them reliable for long-term use in environments where electricity may not be available.
