  • Calibration - GIS Wiki | The GIS Encyclopedia

    Calibration is the validation of specific measurement techniques and equipment. At the simplest level, calibration is a comparison between measurements-one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device.

    3 mins readMost monitors require calibration every 6 months and some are annual, but this may vary depending on the application, manufacturer and even the environment. This can be done manually with a regulator, calibration gas, calibration cap and tubing. Or it can be done automatically with the use of a calibration docking station, such as the Galaxy GX2.
