Calibration Labs and Services
Labs whose accredited scope includes electrical, mass, temperature or pressure calibration. Calibration compares a measuring instrument with a reference of known accuracy and states the difference and its uncertainty. 336 accredited labs in 27 countries have electrical, mass, temperature or pressure calibration in their scope. Most of them are in United States, Canada and Japan. The most common standards in these scopes are ANSI/NCSL Z540-1-1994, ASTM E18 and ASTM E4.

About Calibration
Instruments typically calibrated: multimeters, oscilloscopes, power supplies, electrical calibrators, balances, scales, weights, load cells, force machines, torque tools, thermometers, thermocouples, temperature baths, furnaces, climatic chambers, pressure gauges, pressure transducers, deadweight testers and vacuum gauges. Calibration of length and geometry instruments belongs to dimensional metrology.
