Michelli provides standard traceable and ISO/IEC 17025 accredited mass calibration services for test weights, Class F weights, ASTM weights, metric weights, and analytical mass standards used to verify scales, balances, and precision measurement equipment.
Test weights are used to verify scales, lab balances, and other measurement equipment. If the weight used for verification is out of tolerance, the measurement results that depend on it can become unreliable.
Michelli calibrates a wide range of test weights and mass standards, including equipment purchased from other suppliers. Service options may include standard traceable calibration, ISO/IEC 17025 accredited calibration, on-site service for applicable weights, in-lab calibration, and documentation based on the weight class, size, use, and required scope.
Calibration for Class F, ASTM, avoirdupois, metric, and analytical mass standards.
Calibrated weights help support accuracy checks for scales, balances, and precision measurement devices.
Calibration documentation and asset management to support quality systems, audits, and regulated measurement programs.
Mass measurement is used to determine the amount of matter in an object. In calibration programs, mass standards and test weights are used as known references for checking scales, laboratory balances, and other weighing equipment.
Mass calibration refers to the calibration of test weights or mass standards. When a test weight is calibrated, its value is compared against an appropriate traceable standard to confirm whether it remains within the required tolerance for its class and intended use.
Test weights help quality teams verify lab balances, scales, and inspection equipment.
Calibrated weights support routine accuracy checks between scheduled service visits.
Documented mass calibration helps maintain traceability for measurement and audit needs.
Mass calibration compares a test weight against an appropriate traceable mass standard. The goal is to confirm that the weight value remains within tolerance for its class, size, and intended application.
If a weight is found out of tolerance, adjustment may be available depending on the weight type, construction, condition, and calibration scope. Once calibration is complete, documentation can be provided for quality, audit, and traceability requirements.
Weights are compared against appropriate traceable mass standards.
Results are reviewed against the required tolerance for the weight class.
Adjustment may be performed when available and appropriate for the weight.
Calibration results can be documented for traceability and quality records.
Michelli can help determine the appropriate calibration path based on your test weights, class, application, quality system, and documentation requirements.
Standard traceable mass calibration is available for many test weights and may be appropriate when a customer needs documented calibration traceable to recognized measurement standards.
ISO/IEC 17025 accredited mass calibration is available for applicable weights and scopes when accredited documentation is required by customers, regulations, audits, or quality systems.
Standard mass calibration may be available on-site for applicable test weights. On-site service can help reduce shipping needs and support weights used in plant, scale, and maintenance programs.
In-lab mass calibration may be recommended or required for weights that need controlled environmental conditions, accredited calibration, lower measurement uncertainty, or specialized handling.
Michelli offers mass calibration services for a broad range of avoirdupois weights, metric weights, Class F test weights, ASTM class weights, and analytical mass standards.
Mass calibration documentation may include calibration results, traceability information, weight identification, standards used, and other details based on the selected service scope.
Michelli can help determine whether standard traceable calibration or ISO/IEC 17025 accredited calibration is the right fit for your test weights, quality program, or audit requirements.
Request Calibration Service
Mass calibration services may be available under standard traceable or ISO/IEC 17025 accredited scopes depending on the weight and calibration requirements.
Standard mass calibration may be available on-site or in Michelli laboratories depending on the weights and service requirements. ISO/IEC 17025 accredited mass calibration is performed in ISO 17025 Accredited calibration laboratories.
If you have multiple weights, an equipment list can help Michelli review the weight classes, sizes, quantities, and documentation requirements before scheduling service.
Available for applicable weights depending on location, weight class, and service scope.
Portable weights may be shipped with an equipment list to help streamline intake and service planning.
ISO/IEC 17025 accredited mass calibration is available in accredited calibration laboratories for applicable scopes.
