A spring scale is a mechanical device used to measure force or weight. It operates on the principle of Hooke's Law, which states that the force exerted by a spring is directly proportional to its extension. This makes spring scales an essential tool for various applications in science, industry, and education.

Key Features

4. Home Use:

   • Can be used for hobbies and small DIY projects.
   • Useful for weighing fishing gear, luggage, and more.

Instructions for Use

1. Zero Adjustment:

   • Before use, ensure the scale reads zero by adjusting the calibration knob.

2. Measuring Weight:

   • Hang the object to be weighed on the hook.
   • Read the weight on the scale where the indicator aligns with the markings.

3. Measuring Force:

   • Attach the object to the hook and pull until the desired force is applied.
   • Read the force measurement on the scale.

4. Maintenance:

   • Keep the spring scale clean and free from dust.
   • Store in a dry place to prevent rusting of the spring.

Warranty and Support

• Warranty: 1-year limited warranty against manufacturing defects.
• Support: Customer service available for troubleshooting and replacement parts.

With its blend of accuracy, durability, and ease of use, the spring scale is an indispensable tool for anyone needing reliable force and weight measurements.
