Getting started with PSL
The PSL partners with government agencies, industry, and universities to provide high-quality calibrations and consulting services.
We solve measurement problems and provide calibration services that support the nation’s most challenging needs through our creative personnel; cutting-edge measurement science, facilities, and equipment; and unwavering commitment to quality and customer service.
The PSL maintains measurement and calibration expertise in a variety of areas. View our capabilities here. Each discipline develops and maintains primary standards, secondary standards, consults on measurement problems, and calibrates reference standards. The overall calibration program is accredited by the NIST National Voluntary Laboratory Accreditation Program (105002).
