What is the typical accuracy class of a 1KG calibration weight?

For general laboratory and industrial use, a 1KG calibration weight is commonly OIML Class M1 or F2. Higher precision applications may require Class E2.

How often should calibration weights be re-calibrated?

The re-calibration frequency depends on usage, regulatory requirements, and internal quality procedures. Annually is a common interval, but some applications may require more frequent checks.

What material is best for a calibration weight?

Stainless steel is widely preferred due to its corrosion resistance, hardness, and stability. Other materials like brass are also used, particularly for lower accuracy classes.

Can this weight be used with any balance?

Yes, a 1KG calibration weight can be used with any balance or scale that has a capacity of 1KG or more and requires calibration at that specific point. Ensure the weight's accuracy class is appropriate for the balance's precision.

How should calibration weights be handled?

Calibration weights should always be handled with clean, lint-free gloves or forceps to prevent transfer of oils, dirt, or moisture, which can affect their mass and accuracy.

Typical context for this category of equipment. Always confirm specifics with the seller.

Calibration of laboratory balances and scales in pharmaceutical research and development.
Verification of weighing equipment accuracy in biotech production facilities.
Quality control checks for precision instruments in analytical laboratories.
Setup and adjustment of industrial scales used for ingredient measurement.
Routine accuracy testing for weighing devices in food processing environments.

Nominal Mass: 1 kg (as specified for this unit)
Material: Typically stainless steel, brass, or cast iron for this class of equipment, often with a protective coating.
Accuracy Class: Commonly OIML Class M1, F2, or E2, depending on the required precision for the application. Buyers should confirm with the seller.
Dimensions: Varies by design, but typically compact and designed for easy handling and placement on balance pans.
Surface Finish: Often polished or smooth to minimise dust accumulation and ensure stability.
Storage Requirements: Should be stored in a clean, dry environment, ideally in a dedicated case to prevent contamination and damage.

Calibration weights and kits are essential for maintaining measurement accuracy across laboratories, biotech and pharmaceutical facilities. Buyers typically prioritise certified traceability, material quality and condition of surface finish when purchasing used sets. Industry sentiment favours equipment from established manufacturers with documented calibration history. Common strengths include durability and long operational lifespan when properly stored. When buying used, verify calibration certificates, inspect for corrosion or damage, and confirm all weights in the set are present and accounted for.
