Kaalusid

Kaalusid is the Estonian term for weights used to measure mass on scales and balances. The word denotes multiple calibrated masses that are placed on a balance in order to determine or verify the mass of an object. Kaalusid are fundamental in metrology, the science of measurement, and are used to ensure accuracy in weighing devices across laboratories, industry, and educational settings.

Kaalusid are typically manufactured from corrosion-resistant metals such as stainless steel and are engraved with their mass values. They are sold in sets that cover a range of masses, from fractions of a gram to several kilograms, allowing precise calibration and verification of different instruments. The masses are produced to strict tolerances and carry certificates of calibration that establish traceability to national or international standards.

In practice, calibration weights (kaalusid) are used to calibrate and test balances, beam scales, and digital scales. They enable users to compare the reading of a device against known reference masses, ensuring measurements are accurate and reproducible. The handling of kaalusid requires periodic verification, proper cleaning, and protection from deformation, corrosion, and contamination, which can affect accuracy.

Estonian metrology authorities and international standards bodies oversee the classification, tolerances, and certification of calibration weights. The term kaalusid thus encompasses a range of standardized masses essential for reliable measurement and quality control.
