The division's NVLAP accredited metrology laboratory offers the highest levels of precision measurement and calibration services available in the nation, providing clients a certificate of traceability to the National Institute of Standards and Technology (NIST) for all calibrations performed. 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:
Calibrations and verifications from 1 mg to 100,000 lbs. The Laboratory calibrates weights from 1 mg to 5000 lbs. 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 NIST traceable, NVLAP accredited test report.
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.
Solid density determination, including verifying the accuracy of pycnometers. By using a submerged electronic balance, the Laboratory can determine the density of one-piece mass standards. This is accomplished by comparing the density of the unknown with that of a known laboratory standards in a series of measurements. The Laboratory can also verify the accuracy of pycnometers.
Verify electronic temperature probes and liquid-in-glass thermometers from 0 C to 500 C. With an effective range from 0 C to 500 C, the Laboratory offers NIST traceable verifications of liquid-in-glass thermometers (including total and partial immersion, ASTM, calorimetric, Beckmann, clinical, and kinematic viscosity) as well as electronic temperature measuring systems (including platinum resistance, thermistor and thermocouples). All measurements include a NIST traceable, NVLAP accredited test report.
Volumetric and gravimetric calibrations for laboratory and field standards, from microliter pipettes up to 1,500 gallons. The Laboratory provides calibration services for many types of volume standards, from microliter pipettes to 1,500 gallon provers. All measurements include a NIST traceable, NVLAP accredited test report.
Traceable verification of measuring tapes and rules. The Laboratory can verify the accuracy all conventional field length standards up to 200 feet, or longer by request, including surveyor tapes, tape measures, steel rules, and pi tapes.
