Specialized measuring instruments for accurately measuring mechanical forces such as tensile force, compression force, and push force in manufacturing sites. Used for monitoring processing force in press machines, measuring breaking strength in material testing, managing tightening force in assembly processes, and evaluating product strength in quality inspection. Includes digital force gauges, analog push-pull gauges, load cell type load meters, and handheld force meters, capable of measuring in N (Newton), kgf, and lbf units. Essential measuring instruments for mechanical quality control in press processing, injection molding, assembly lines, and material testing laboratories, clearly distinguished from torque meters and pressure gauges in measurement targets.
