Measurement Instruments: Purpose: Calibration ensures that measuring instruments provide accurate and reliable results. Process: Instruments like thermometers, pressure gauges, scales, and more are adjusted to a standard reference. The readings are then compared, and adjustments are made to bring the instrument into alignment with the reference.
