The Metrology Lab provides NIST traceable calibrations for mass and volume standards, calibrates equipment for our state inspectors and private scale and pump service companies for the enforcement of weights and measures regulations.

All Calibration services are available by appointment only to any business, industry, or government agency requiring NIST traceability for a fee. To schedule a calibration appointment, please call (803) 253-4052. Please note the lab will schedule on average several months in advance and equipment submitted without an appointment may suffer delays in service. The Metrology Lab requires the completion of the Calibration Request Form and a copy included with shipment before the equipment will be calibrated.  If submitting a volume measure, a Certification of Prover Cleaning must also be completed and included with each shipment. Failure to complete either form will delay the processing of the equipment until the form is completed and submitted.

Cleaning of Equipment

Equipment submitted for calibration should be delivered/shipped to the lab in a ready to test condition as found in NIST Handbook 105-1 (Mass), NIST Handbook 105-3 (Volume), and NIST Handbook 105-8 (Weight Carts).  Any equipment submitted that does not meet calibration requirements may be subject to rejection and returned, at the customer’s expense.

Mass:

  • Stainless steel weights should be free of rust, dirt or debris buildup.
  • Cast-iron weights should be free of rust, loose paint, dirt or debris buildup.

Volume:

  • Small provers should be cleaned with a mild detergent. Make sure all soap residue is thoroughly rinsed away, the sight glass tube is cleaned, and scale plate is readable.
  • Mild steel and large-volume provers should be properly coated with paint.
  • Large volume provers should be well cleaned inside and out with detergent and water. All discharge drain hoses and/or pipes must be cleaned.
  • LP-gas provers must be depressurized and thoroughly flushed with water prior to submission for calibration. Also, all drain hoses and pipes must be clean.

Weight Carts:

  • All fluids, tires, batteries, etc., must be checked prior to submission for calibration.
  • Where necessary weight carts must have a proper coat of paint and well cleaned.

Fee Schedule

Due to the high number of late payments and no payments in the past, calibration certificates will NOT be sent until the customer invoice is paid in full.  The South Carolina Metrology Lab accepts payment by credit card (small fee associated with this form of payment) and check.

See our Fee Schedule.
