In order to test commercial weighing or measuring devices, inspectors and service agencies must use accurate standards that are traceable to a national standard. The National Institute of Standards & Technology (NIST) provides oversight for all state laboratories, insuring that the calibration procedures and the standards used by state laboratories meet national accuracy requirements.
The West Virginia State Measurement Laboratory is located in St. Albans, WV, and houses the state standards of mass and volume. This laboratory also maintains measurement traceability to the National Standards in Gaithersburg, Maryland.
Trained and certified metrologists calibrate weighing and measuring standards that are used in commerce in our state, including those used by service agencies that perform service work on commercial devices. Metrologists are trained and certified by NIST.
Calibrations are performed by appointment only, and charges apply to most tests and calibrations.
To schedule a calibration appointment, contact our Weights & Measures Laboratory at Weights@wv.gov or (304)722-0602.
