Mechanical Scales and Balances

The main difference between a mechanical spring balance or force gauge and a digital force gauge can be found in their construction. Mechanical gauges, similar to spring scales or a strain gauge, operate on a spring component that can be used to measure the weight of an object only. A digital force gauge uses a load cell component rather than a spring, and makes use of a variety of smart features including peak hold and statistical analysis, but tends to be used for the same overall purpose as a mechanical force gauge.

What's the difference between a mechanical balance and a digital balance?

A digital balance uses electrical components and sensors which can be used for higher levels of precise testing powered by batteries or electricity using an AC adapter. A mechanical balance is more cost effective, using counterweights and levels to measure mass, and requiring no electricity. A mechanical balance typically reads up to 0.01g depending on the quality and condition of the balance.

What are the best practices when using a mechanical balance?

The best practice while using a mechanical balance is firstly to ensure its well maintained - including regular cleaning, avoiding corrosive materials and calibrating periodically to ensure accuracy.

It's important to place the balance on a level, stable surface. Ensure that the balance reading is set to zero before use and the weighing surface is free from residue or oils. Lastly, avoid overloading the mechanical balance as exceeding its weight capacity could cause damage.

Where are mechanical balances most commonly used?

Mechanical Balances are often used in educational labs such as in universities, colleges and schools. They can also be used out in the field where there is no electricity.

How do you calibrate a mechanical balance?

To calibrate a mechanical balance you need to use certified calibrated weights. You will need to ensure the balance is on a stable surface, and the reading is set to zero. Then, add the calibration weights and check the reading on the balance corrsponds exactly with the known weight of the test weight. Please ensure you follow the instructions provided with the balance to perform a calibration adjustment.
