Detector calibration is a process in which the measurements taken by a detector are adjusted or standardized to ensure accuracy and precision. This is typically done by comparing the detector's response to known standards or reference materials to determine any deviations or errors in the measurements. Calibration is essential in ensuring the reliability of data gathered by detectors in various fields such as environmental monitoring, industrial quality control, and scientific research. By calibrating detectors regularly, researchers can ensure that their measurements are accurate and trustworthy for their intended purposes.
