Standard Reference Instruments

NIST supports accurate and compatible measurements by producing and providing Standard Reference Instruments that transfer to customers the ability to make reference measurements or generate reference responses based on specific NIST reference instrument designs.

Due to NIST’s current limited operational status, some calibration services and standard reference instruments may not be presently available or may experience unusual delays. Please contact the technical contact for the service or reference instrument before placing an order to check the status.

NIST is consolidating its provision of reference instrumentation and devices into a new Standard Reference Instrumentation (SRI) program.
