Analog scales are measuring devices that display weight using a dial and a pointer. They operate on mechanical principles, where the weight of an object causes a spring or lever to move, indicating the measurement on a graduated scale. These scales are often used in kitchens, laboratories, and for personal weight measurement. Unlike digital scales, which provide a numerical readout, analog scales require users to interpret the position of the pointer against the scale markings. They are generally simple to use and do not require batteries, making them reliable for various applications, including cooking and fitness tracking.
