HSCo stainless-steel calibration weights are the reference masses you place on a weighing scale or balance to check that it reads true. They come in single pieces from 1 g to 50 kg, are made of 304-grade stainless steel with a mirror finish, carry laser-etched values, and are supplied with two years of government stamping.
What sets these weights apart
- 304 stainless steel. A non-magnetic grade, which matters when the weight goes on a precision balance that works by magnetic force compensation: a trace of magnetism in the weight would upset the calibration. Weights of 202-grade steel should be avoided for this work.
- Mirror polish. A smooth, polished surface gives dust and grime nowhere to settle, so the mass stays what it was stamped at.
- Laser-etched value. The value stays readable after years of handling, unlike printed marks.
- Stamping included. Each weight has a single hole on top for the government seal and comes with two years of stamping.
- Knob-top cylinders. The classic shape is easy to pick up and stands steady on the pan.

Choosing the right weights
- Cover your scale’s range. Pick weights that add up to the points you check, usually a small load, the middle and close to the scale’s full capacity.
- Match the job. For a laboratory balance or a set of classed weights with a certificate, see our weight boxes, E1 to M2.
- Keep them clean. Handle weights with gloves or tweezers, never bare fingers, and store them in a box: skin oil and dust add mass.
Questions buyers ask
What are calibration weights used for?
To check and adjust weighing scales and precision balances: you place a known mass on the scale and compare it with the reading.
Why stainless steel, and why 304 grade?
Stainless steel resists rust, and the 304 grade is non-magnetic, which precision balances need. Avoid 202-grade weights for calibration.
Which sizes can I buy?
Single weights from 1 g to 50 kg: 1, 2, 5, 10, 20, 50, 100, 200 and 500 g, and 1, 2, 5, 10, 20 and 50 kg.
Are they government stamped?
Yes. Each weight has a stamping hole on top and comes with two years of government stamping.
Can I buy a complete set instead?
Yes. Our weight boxes hold a full set from 1 mg to 200 g in a case, in accuracy classes E1 to M2.
