Physics Mass Comparison Balance

Product Code : SCL-AM-11242

The Physics Mass Comparison Balance is a mechanical laboratory instrument used for comparing the mass of an unknown object with known reference masses. It is intended for school, college and technical physics laboratories where students learn mass measurement, balance equilibrium and correct handling of standard weights.

Product Description

The balance works by placing the test object on one pan and known masses on the opposite pan. The beam moves until both sides produce equilibrium about the central support. When the pointer settles at the reference position, the object mass is determined from the total known masses used.

The product may use an equal-arm beam, two pans, a central pointer and a zero-adjustment arrangement. Exact construction, weighing capacity, sensitivity, readability and pan dimensions must be confirmed for the approved model. Buyers can compare it with other laboratory balances before selecting the required configuration.

Key Features

• Direct mass comparison: Compares an unknown object against known laboratory masses.
• Two-pan arrangement: Separates the test object and reference masses during weighing.
• Visible equilibrium indication: A beam or pointer shows when the two sides are balanced.
• Manual zero adjustment: Allows the unloaded balance position to be corrected before use, subject to model design.
• No electrical supply required: Operates mechanically during standard comparison activities.
• Educational construction: Demonstrates equilibrium, mass comparison and measurement procedure.
• Reusable laboratory format: Suitable for repeated supervised practical work.

How to Use the Physics Mass Comparison Balance

1. Place the balance on a firm, level and vibration-free table.
2. Ensure both pans are clean, empty and correctly positioned.
3. Adjust the unloaded balance until the pointer indicates zero.
4. Place the test object gently on one pan.
5. Add known masses to the opposite pan using suitable forceps.
6. Use progressively smaller masses as the balance approaches equilibrium.
7. Allow the pointer to settle before recording the total mass.
8. Remove the object and return every reference mass to its case.

Safety and handling: Do not exceed the verified capacity. Avoid dropping objects or masses onto the pans, and never press the beam or pointer by hand.

Care & Maintenance

• Keep the beam, support points and pans clean and dry.
• Store reference masses in their designated case.
• Check the zero position before every weighing session.
• Arrange inspection or calibration when quantitative accuracy is required.

Frequently Asked Questions

What is a Physics Mass Comparison Balance used for?

It compares the mass of an unknown object with known reference masses until the balance reaches equilibrium.

Does the balance measure mass or weight?

It compares mass. The gravitational effect acts on both sides of the balance and is cancelled in the comparison under normal laboratory conditions.

Are standard weights included?

Weight-set inclusion has not been verified. A compatible Brass Mass Set 1000g is listed separately.

What is the maximum weighing capacity?

The capacity is model-specific and must be confirmed before publishing or ordering.

Does the balance require electricity?

A conventional mechanical comparison balance does not require electrical power.

Can it be used for formal calibration work?

Only when its performance, reference masses and calibration traceability meet the required procedure. No calibration class has been verified for this model.
