ESAL Spring Balance
Product Code : SCL-LM-11169
Quick answer: The ESAL Spring Balance is a dual-scale spring balance that reads 0-250 g and 0-2.50 N, used in school and college physics to measure weight and force and to show how a spring extends under load. It hangs from a top loop and carries the load on a lower hook. Lab Exports manufactures it in Delhi for schools, colleges and universities.
Specifications

| Principle | Extension of an internal spring read on the scale |
How it is used
A spring balance works on Hooke's law: within its elastic limit, the extension of a spring is proportional to the force applied, F = kx. The pointer moves along the graduated scale in proportion to the load, so the scale can be marked in newtons for force and in grams for the mass that produces that weight. Having both scales on one balance lets students compare a mass reading with its weight in newtons through W = mg.
- Hang the balance from its top loop on a stand or hook so that it hangs freely and vertically.
- Check that the pointer reads zero with no load attached.
- Attach a known mass to the lower hook and let the pointer come to rest before reading.
- Read both scales and record the mass in grams and the force in newtons.
- Add masses in steps and plot force against extension to show Hooke's law.
Key features
- Dual scale reading 0-250 g and 0-2.50 N on one instrument.
- Top suspension loop for hanging from a stand or support.
- Lower hook for masses and experimental objects.
- Direct reading of force and weight for introductory mechanics.
- Shows spring extension increasing with load for Hooke's law lessons.
