Newton Kraft Spring Scale — durable, accurate spring dynamometers for classroom and lab use Key benefits Reliable force measurement: Clear, labeled dual scales and an all-steel spring provide repeatable readings for gravimetric and tensile force measurements. Built for repeated use: Safe materials and detailed workmanship resist deformation and wear, extending product life in classroom and laboratory settings. Easy to read and adjust: Transparent dual scales let you observe spring extension and retraction; a manual adjustment nut and large metal handle simplify zeroing and handling. What’s included Package includes: 6 pcs Spring Dynamometer (1–30 N) Main features Brand/model: Newton Kraft spring scale series, suitable as Newton spring scale, suspension scale, and hanging scale (including 5 N range usage scenarios). Dual clear scales: Transparent housing with double scales and clear labeling for straightforward reading of force in Newtons. Construction: Non-deformation all-steel spring, large metal handle, manual adjustment nut, and safe, durable materials with careful workmanship. Appearance and practicality: Hanging tube design with a clean, practical appearance suitable for frequent use. How it solves problems Simplifies force experiments: Provides consistent, visible measurements so students and technicians can compare results and learn correct force-reading techniques. Reduces downtime and replacements: Strong materials and precise assembly lower the risk of spring deformation and frequent replacement. Improves accuracy and repeatability: The dual-scale, transparent design and manual zero adjustment help eliminate reading errors and drift. Typical applications Classroom physics experiments: Ideal for demonstrations of Hooke’s law, gravitational force, and basic mechanics experiments. Laboratory measurements: Use for routine tensile or gravimetric checks, small load testing, and equipment calibration tasks where compact, reliable dynamometers are needed. Field or workshop use: Portable hanging/tension measurements for quick checks of weight, tension, or small force applications. Specifications and use notes Force range (unit included with set): 1–30 N per dynamometer (set of six). Functions: Measurement of gravimetric (weight) and tensile (pull) forces; can be used as suspension/hanging scales. Adjustment: Manual adjustment nut for zeroing; observe spring movement through transparent casing for more accurate readings. Trustworthy, practical, and built for repeated educational and laboratory use, the Newton Kraft Spring Scale set provides a straightforward solution for measuring forces between 1 and 30 N.
