Product Description
The METTLER TOLEDO ASTM Class 4 Master Weight Set is the definitive calibration standard for laboratories requiring full-range verification capabilities. Encompassing 24 precision weights from 1 milligram to 500 grams, this set is engineered to calibrate and validate the performance of analytical, precision, and high-capacity balances with absolute traceability.

Key Features & Advantages:

• Unmatched Range in a Single Set (1mg–500g): Provides the most extensive mass coverage available in a Class 4 set, enabling comprehensive calibration from the lowest microbalance capacities up to 500 grams, eliminating the need for multiple, separate sets.

• End-to-End Robotic Calibration Assurance: Every weight, across the entire 6-order-of-magnitude range, is certified using automated robotic calibration technology. This ensures unparalleled consistency, reduces measurement uncertainty, and provides a single, trustworthy certificate for the complete system.

• Uniform High-Density 316 Stainless Steel: All weights are manufactured from the same high-grade 316 stainless steel with a consistent density (7950 kg/m³), ensuring predictable behavior in air buoyancy calculations and long-term stability against corrosion and wear.

• Sealed Adjustment Cavity Design: Features a sealed construction that protects the internal adjusting material from environmental contaminants, safeguarding mass integrity and ensuring reliable performance over extended periods in laboratory conditions.

• Comprehensive Professional Toolkit: Delivered as a complete system in a protective storage case with handling accessories, offering an organized, portable, and immediately deployable solution for critical calibration workflows.
