Metrology Lab

The division's NVLAP accredited (lab code 105003-0) metrology laboratory offers the highest levels of precision measurement and calibration services available in the nation, providing clients calibration certificates traceable to the international system of units (SI) through the National Institute of Standards and Technology (NIST) for all calibrations performed. Calibration certificates using the laboratory’s NVLAP (105003-0) accredited services are available for the majority of our scope.

The laboratory meets all ISO, FDA, NRC, FAA and ANSI/NCSL Z540-I requirements. The laboratory also offers an automatic recall system for all equipment based on a specified calibration interval.

Measurement services available to businesses include:

Mass Standards and Test Weights

  • The laboratory calibrates weights from 1 mg to 5000 lb using computer-interfaced balances and mass comparators to ASTM, NIST and OIML Classes. The laboratory can calibrate any type of weights from brass working class to highly polished stainless steel precision weights. All measurements are performed in a state-of-the-art environmentally controlled laboratory on the finest equipment available. All measurements include a calibration certificate traceable to the SI.
  • Because the influx of a magnetic field can disrupt the true mass of a weight, the Laboratory will also test precision stainless steel weights for magnetic flux density.
  • Fees: $182 per hour


  • The laboratory provides calibration services for many types of volume standards, from 10 mL flasks to 1,500 gallon provers. All measurements include a calibration certificate traceable to the SI.
  • Fees: $182 per hour
