- High quality construction and a distinctive appearance make these scientific spring scales popular and practical for use in classrooms, labs, or as a general force gauge. - Each scale features a top hook for easy hanging and a bottom hook to secure the object to be weighed, offering convenient setup for experiments. This is a versatile spring scale for experiments. - Scientific spring scales are ideal for physics demonstrations and experiments, for measuring weights and exploring the physics of force and mass. Cylinder spring scale with two scales provides dual readings. - Newton force spring scale: built with premium materials and precise workmanship, a durable cylinder spring scale with two measurement scales for reliable results. 2-3 use scenarios - Classroom demonstrations: hang different objects from the bottom hook to observe readings and discuss weight, mass, and gravitational force. - Lab experiments: measure forces during experiments, compare weights, or verify Newtonian principles with a stable, two-scale spring scale. - Student projects: practical tool for exploring how mass and force relate under different conditions, or as a reliable force gauge during experiments.
