Quick Answer: The ESAL Spring Balance is a spring-based physics instrument for measuring pulling force or suspended weight, and for showing how a spring extends under load.
Last updated: October 2026
Key Features
Measures force or suspended weight on a spring-based scale.
Shows the relationship between load and spring extension.
Supports Hooke’s law, gravity and mass-weight experiments.
Measures apparent weight in buoyancy activities.
Can be used with hanging masses, small objects and mechanics setups.
About This Product
The balance is suspended vertically from its top ring or support point and checked for a zero reading before any load is added. The object or hanger goes on the lower hook, and the reading is taken once the spring stops oscillating. Students use it for force measurement, Hooke’s law work and lessons on the difference between mass and weight.
Frequently Asked Questions
Q1. Why should the scale be read at eye level? Reading the scale at eye level reduces parallax error. The spring should also stop oscillating before the reading is recorded.
