Our Mass Calibration Services

Weighing instruments play a critical role in dosing, formulation, shipping, inventory management, and regulatory compliance.

When they drift out of specification, the impact can be extensive—incorrect batches, inventory errors, rejected shipments, compliance issues, and significant financial losses. The Accredited Labs network offers complete mass calibration services that keep your equipment performing within its required accuracy ranges.

Our Process 

Mass calibration involves verifying and adjusting weighing instruments across their full operating ranges using certified reference mass standards with known, traceable values. Each device is evaluated to identify any deviations from its intended performance.

Skilled technicians test instruments using certified weights throughout their weighing capacities, document all variations, and make the adjustments needed to restore accuracy. If an instrument cannot be restored to the required accuracy range, you receive detailed reporting with the data necessary for corrective action, maintenance planning, or replacement decisions.

All mass calibrations follow internationally recognized protocols, including NIST Handbook 44 and relevant international weighing standards. Each instrument is returned with documentation linking its accuracy to national mass standards—supporting regulatory compliance, quality management systems, and commercial weighing requirements.

Types of Weighing Instruments We Calibrate

Our comprehensive mass calibration services cover the complete spectrum of weighing technologies used across industries:

  • Analytical and Precision Balances: High-precision laboratory instruments used for pharmaceutical compounding, chemical analysis, and quality control applications. These instruments require specialized calibration procedures and controlled environments to achieve their specified accuracy levels.
  • Industrial Platform Scales: Heavy-duty weighing systems used in manufacturing, warehousing, and shipping applications. Calibration ensures accurate weighing of products, materials, and packages across various industrial environments and loading conditions.
  • Truck and Vehicle Scales: Large-capacity weighing systems used for commercial vehicle weighing, shipping verification, and regulatory compliance. These systems require specialized calibration procedures and certified test weights to ensure accuracy across their full capacity range.
  • Bench and Counting Scales: Mid-range weighing instruments used for parts counting, quality control, and general weighing applications. Calibration ensures accurate weighing and counting functions across various industrial and commercial applications.
  • Crane and Hanging Scales: Suspended weighing systems used in material handling, construction, and industrial lifting applications. These instruments require calibration under various loading conditions and environmental factors that affect their accuracy.
  • Floor and Pallet Scales: Low-profile weighing systems designed for warehouse and industrial applications where materials are weighed on pallets or in containers. Calibration ensures accurate weighing of various load types and distributions.
  • Checkweighers and In-Motion Scales: Dynamic weighing systems that weigh products while in motion on production lines or conveyor systems. These instruments require specialized calibration procedures that account for dynamic effects and speed variations.
  • Retail and Commercial Scales: Point-of-sale weighing systems used in retail, grocery, and commercial applications. Calibration ensures compliance with commercial weighing regulations and fair trade practices.
  • Shipping and Postal Scales: Weighing systems used for package weighing, shipping cost calculation, and logistics applications. Accurate calibration prevents shipping cost errors and ensures compliance with carrier requirements.
  • Specialty and Custom Weighing Systems: Application-specific weighing solutions including tank scales, hopper scales, belt scales, and integrated weighing systems. These require customized calibration approaches based on their specific design and application requirements.
