5N Spring Dynamometer — Reliable, easy-to-read force meter for student experiments Key benefits Accurate and repeatable measurements: The fatigue-resistant spring maintains measurement precision over repeated use, making the dynamometer reliable for classroom experiments and repeated testing. Easy for students to use: An adjustable pointer and clear scale plate let learners read forces quickly and reduce reading errors during demonstrations and lab work. Durable and portable: Constructed from quality plastic and iron, the device is stable and built to withstand routine school use while remaining compact and lightweight for easy storage and transport. What it does and why you need it Measures forces up to 5 N with a spring-based mechanism designed for educational physics experiments. Simplifies hands-on learning by providing a straightforward, mechanical way to observe and quantify force, tension, and basic mechanics principles. Reduces time spent on setup and interpretation thanks to a readable scale and an adjustable pointer that can be zeroed or aligned for clearer results. Key features Capacity: 5 N spring dynamometer for small-force measurements appropriate to elementary and middle school mechanics. Durable materials: High-quality plastic body with iron components for structural stability. Readability: Adjustable pointer and scale plate for precise, easy reading during demonstrations or student measurements. Long-term reliability: Spring designed to resist fatigue so measurements remain consistent after repeated use. Compact, lightweight design for classroom portability and convenient storage. Typical applications Classroom physics labs: Measure tension, pull forces, and simple experiments on springs and pulleys for grades K–8. Teacher demonstrations: Quick setup for in-class demonstrations of Newton’s laws, force equilibrium, or friction experiments. Student practice and homework labs: Portable tool for small-group activities, field demonstrations, or take-home assignments that require measuring forces up to 5 N. Compatibility and use notes Designed for basic mechanics experiments in elementary and middle school curricula. Works with standard classroom setups (hooks, small masses, pulleys) to measure tensile and pulling forces within its 5 N range. No power source required; purely mechanical operation simplifies maintenance and supervision. Materials and performance Body: High-quality plastic for light weight and ease of handling. Internal/structural parts: Iron components where strength is needed. Spring: Fatigue-resistant spring for consistent, repeatable readings over multiple uses. What makes it stand out Combines student-friendly readability with durable construction and a fatigue-resistant spring, delivering reliable force measurements for routine educational use without complicated setup or calibration. Packaging and storage Compact design fits classroom storage and student experiment kits; easy to carry between lab stations or classrooms.
