Gauge calibration is the process of verifying and adjusting the accuracy of measurement instruments to ensure they provide precise and reliable readings. This process is essential for maintaining high standards of quality control and ensuring that measurement tools, such as micrometers, calipers, pressure gauges, and temperature sensors, conform to established tolerances and industry standards. Calibration involves comparing the readings of the gauge against a known reference or standard, and making adjustments as necessary to correct any discrepancies. Regular calibration is critical in industries such as manufacturing, aerospace, automotive, and medical equipment, where even small measurement errors can have significant consequences. Gauge calibration helps maintain accuracy, prolong tool life, and ensure compliance with regulatory requirements.
