The precision slotted mass set 2.5kg is a physics laboratory mass set used for applying known nominal loads during mechanics, force and motion experiments. It is intended for secondary-school, college and university laboratories that require removable masses for pulley systems, spring experiments, moments, acceleration studies and other controlled loading activities.
Product Description
The STEMAids Precision Slotted Mass Set 2.5kg provides a nominal combined mass capacity of 2.5 kg. Slotted masses are designed to be added to or removed from a compatible hanger without dismantling the complete experimental arrangement, making load changes quicker during repeated measurements.
The term “precision” appears in the product name, but no verified tolerance or calibration class is currently published. The individual mass values, hanger mass, material, surface finish and number of pieces must be confirmed before quantitative procurement. Related equipment is available in the STEMAids physics laboratory products range.
Key Features
- 2.5 kg nominal capacity: Provides a combined set capacity stated as 2.5 kg.
- Slotted configuration: Allows compatible masses to be added or removed without disconnecting the hanger.
- Incremental loading: Supports controlled changes in applied mass according to the confirmed mass combination.
- Multi-experiment use: Suitable for compatible mechanics, pulley, spring and force setups.
- Hands-on measurement: Helps students relate applied mass to weight, extension, acceleration and turning effect.
- Reusable laboratory resource: Supports repeated practical sessions when stored and handled correctly.
- Transparent accuracy status: Tolerance and calibration must be verified before precision measurement claims are made.

How to Use the Precision Slotted Mass Set 2.5kg
- Confirm the required load and identify the correct mass combination.
- Inspect the hanger, masses, cord and supporting apparatus.
- Secure the hanger to the experimental setup before adding masses.
- Add slotted masses evenly and ensure each piece rests flat.
- Increase the load gradually while observing the apparatus limit.
- Include the hanger mass when calculating the total suspended mass.
- Record readings only after the system becomes stable.
- Remove masses individually and return them to their storage positions.
Safety note: Keep hands and feet clear of suspended masses. Do not exceed the rated capacity of the hanger, cord, spring, pulley or supporting frame.
Care & Maintenance
- Keep the masses dry and wipe them after handling.
- Protect slots, edges and hanger stems from impact or deformation.
- Store each mass in a designated rack or compartment.
- Check mass values periodically when measurement traceability is required.

Frequently Asked Questions
What is a 2.5 kg slotted mass set used for?
It is used to apply known nominal loads in mechanics experiments involving springs, pulleys, levers, friction and acceleration.
Does the 2.5 kg capacity include the hanger?
The available information does not confirm whether the stated capacity includes the hanger. Request the complete mass schedule before ordering.
What mass increments are supplied?
The individual denominations and quantities are not published. They should be listed in the approved bill of materials.
How accurate are the slotted masses?
No tolerance or accuracy class is verified. Do not treat the set as calibrated laboratory weights unless supporting documentation is supplied.
What material are the masses made from?
The material and surface finish are not currently published and should be confirmed for corrosion resistance and procurement compliance.
Can the set be used in school laboratories?
Yes. It is suitable for supervised mechanics practicals when the supporting apparatus is rated for the applied load.
