Tubular Spring Balance – 20 N / 2000 g

This 20 N tubular spring balance (Newton meter) is designed for measuring forces and exploring weight, mass and Hooke’s law in school science and physics experiments. Its robust transparent plastic body allows students to observe the spring mechanism while reading the dual scales in newtons and grams.

• Measuring range: 0–20 N / 0–2000 g
• Supplier-stated tolerance: ±0.4 N / ±40 g
• Body: robust transparent plastic
• Overall length: approximately 240 mm
• Scales: force in newtons (N) and mass equivalent in grams or kilograms
• Fittings: upper suspension loop and lower hook
• Adjustment: zero adjustment

For classroom activities, suspend the balance vertically, check the zero before use and apply loads within the marked range. The mass scale is a convenient approximate equivalent under normal Earth gravity; newtons are the unit of force.

Complementary equipment: slotted masses and carriers can be used for demonstrations of force and extension.
