The Montana Weights & Measures Bureau also operates an NIST recognized metrology lab. The lab is equipped to certify ASTM Class III echelon and class "F" weights for both the bureau's test standards and the standards used by registered repair agencies to calibrate scales. The metrology lab will also certify test weights used by private industry for their in-house weighing and calibration.
The metrology lab is also equipped to handle volumetric testing of all types ranging from five gallon to 1000-gallon test measures and including standards used to calibrate LPG and NH3 meters.
