Calibration

NDBC strives to provide its customers with the highest quality data possible. NDBC calibrates each sensor prior to deployment. After two years of service, sensors still in operation at an NDBC station are replaced with recently calibrated instruments so that those on station can be returned to NDBC for post-deployment calibration analysis as well as refurbishment and recalibration.
