Are the sensors used at NDBC sites periodically calibrated?

NDBC uses a variety of manufacturers for each type of sensor. The following is a list of the most recent manufacturers of instruments which NDBC uses:


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.
