What’s the difference between a mechanical and a digital dynamometer?
Mechanical dynamometers (also known as analog dynamometers) have internal moving parts to calculate the applied force. Mechanical dynamometers were developed by Dillon in 1937 and do not require batteries or a power source to operate.
Digital dynamometers (also referred to as load cells) have no moving parts, utilize strain gauge technology to calculate the applied force, and require batteries to operate. Digital dynamometers have more features, are more accurate, and offer higher capacities.
