Why calibration is required ?
Initial Calibration - New palnt or equipment commissioning Verify vendor data - Insure accuracy of measurement.
Ongoing Calibration-
Minimize and control random and systematic errors Compare and complement the quality and reliability of measurement by comparison to international standards. Quality system requirements.Ensure consistent product quality. Safety.
