Optimized spring scale for education, fieldwork, and experiments. - Versatile use: suitable for classroom and outdoor work to measure weights and explore the physics of force and mass. - Simple hanging and weighing: top hook for easy hanging, bottom hook to attach objects; clear tube scale for quick readings; dual-scale display for metric and imperial units. - Durable stainless steel: stainless steel spring and hook resist corrosion and deformation; built for long life. - Professional-grade performance: reliable, lightweight materials; withstands long operation time; dual scales enable fast unit conversion. - Portable and compact: lightweight and easy to carry between sites and classrooms. Practical applications: - In science class: compare weights of rocks, leaves, and lab items to study mass and force. - In the field: weigh samples or field gear on site without returning to the lab. - In workshops or kitchens: weigh small parts or ingredients for precise measurements.
