Official document verifying measurement instrument calibration against standards.
A calibration certificate is a formal document issued by an accredited laboratory or calibration service provider that confirms a measurement instrument or device has been calibrated against traceable reference standards. It provides documented evidence of the instrument's accuracy, measurement uncertainty, and compliance with specified tolerances at the time of calibration. The certificate includes calibration results, measurement conditions, equipment used, and the date of next required calibration.
