Test weights – find manufacturers and suppliers

Test weights are specially calibrated weights used to check or calibrate the accuracy and reliability of scales and other measuring devices. They are often used in laboratories, production facilities and other environments where accurate measurements are required.

Test weights are often made of high-quality materials that ensure accurate and stable mass over long periods of time. Common materials include stainless steel, brass or cast iron.

Test weights are calibrated to their exact mass and are usually clearly labeled to indicate their nominal mass. This calibration is done according to national or international standards to ensure that the measurements are accurate.

Test weights are divided into different classes depending on their accuracy and tolerance. The most common classifications are E1, E2, F1 and F2 according to the OIML (International Organization of Legal Metrology) standards.

Test weights are used to check or calibrate the accuracy of scales and other measuring devices. This is normally done by comparing the measured mass with the known nominal mass of the test weight.

Test weights must be stored and handled carefully to maintain their accuracy. They should be protected from dust, moisture and other contaminants and regularly checked and recalibrated to ensure they are accurate.

Test weights play a crucial role in ensuring the accuracy and reliability of measurements.
