A portable digital force measuring instrument designed specifically for high school and university physics, general technology, STEM courses. It can complete tension/pressure measurement and data recording with one click, helping students intuitively understand concepts such as Newtonian mechanics, material mechanics, and energy conversion. One click reset and peak holding: Capture the maximum force value for easy analysis of instantaneous impact experiments. Application experiment: Newton's Third Law: Two people pull each other to compare readings; Hooke's law: determination of spring stiffness coefficient; Friction coefficient: measurement of inclined slider tension; Function and capability: Comparison of sliding force of small cars at different heights; Simple material testing: rubber bands, fracture strength of 3D printed parts.
