HÄFNER test weights, weights and mass standards are used in many areas where mass, weight force, calibration, adjustment and quality assurance play an important role. Applications range from laboratories and industry to balance manufacturers, national metrology institutes and legal metrology authorities.

Depending on the application, different accuracy classes, designs, nominal values and versions are used. HÄFNER supports you in selecting suitable test weights, weight sets and mass standards for your specific measuring or testing task.

• Calibration, adjustment and testing of balances
• Manufacture and service of balances and measuring equipment in weighing technology
• Quality assurance in the chemical, pharmaceutical, medicinal and food industries
• Test equipment in general industry for measuring and weighing
• Mass standards for the dissemination of the unit of mass in national metrology institutes
• Mass standards for legal metrology and verification authorities
• Mass standards for calibration laboratories in industry and research
• Weights for training, education and further education
• Adjustment and calibration standards for tensile, compression, torque and flow measurements
• Weighing instruments in trade, e.g. for mechanical balances, table balances and decimal balances

Test Weights for Balances and Measuring Equipment

Test weights are used for the calibration, adjustment and verification of balances. They enable comparison between the displayed value of a balance and a traceable standard with a known value.

This makes test weights important test equipment for quality assurance, production control, laboratory applications, service work and regular balance inspections.

Mass Standards for Metrology and Calibration Laboratories

Mass standards are used for the dissemination of the unit of mass and for the traceability of test weights. They are used in particular in national metrology institutes, legal metrology authorities and accredited calibration laboratories.

Regular calibration and recalibration document traceability to national or international standards and ensure the long-term usability of the weights.
