About the product
- Set of six tubular spring balance/scales with different measurement ranges for determining weight and exploring physics principles of force and mass
- Scales are graduated in grams (g) and Newtons (N) and are color-coded to distinguish between the ranges
- Each scale has a ring at the top for hanging, and an S-hook at the bottom for attaching the sample to be weighed
- Clear plastic housing allows observation of the extension and retraction of the spring
- Maximum load is 250g/2.5N for the blue scale, 500g/5N for the green scale, 1000g/10N for the tan scale, 2000g/20N for the red scale, 3000g/30N for the white scale, and 5000g/50N for the yellow scale
