Product Description
The METTLER TOLEDO ASTM Class 1 Ultimate Range Reference Set is the most comprehensive and precise mass standard available, encompassing an unparalleled spectrum from 1 milligram to 5 kilograms. This 28-piece set is engineered for the apex of metrological science, providing primary reference standards for national institutes and industries where the highest accuracy across both micro and macro weighing capacities is non-negotiable.

Key Features & Advantages:

• Unprecedented Range with Class 1 Accuracy: Defines the benchmark by offering the highest precision tolerances (ASTM Class 1) across the widest commercially available range, establishing a single, authoritative set capable of calibrating the entire hierarchy from microbalances to industrial platforms.

• Exacting Metrological Specifications: Fabricated from premium 316 stainless steel with rigorously controlled density and minimal magnetic susceptibility (X ≤ 0.03), ensuring performance integrity in precision mass comparators and controlled environments where even nanogram-level stability is required.

• Automated Robotic Perfection: Each weight is the product of fully automated robotic manufacturing, achieving geometric perfection, surface excellence, and mass consistency that satisfies the most stringent requirements for primary and secondary reference standards.

• Fully Sealed for Maximum Permanence: The complete set features a sealed adjusting cavity design, including the substantial 5 kg weights, providing an impervious barrier against environmental factors to guarantee century-level stability as a fixed reference asset.

• Foundational Asset for Highest-Level Calibration Chains: Presented without certification, this set is the ultimate choice for metrology institutions and corporate standards laboratories that define their own traceability to the International System of Units (SI) or require custom certification protocols.
