Product Description
The METTLER TOLEDO ASTM Class 1 High-Range Weight Set is a master-grade calibration standard designed for laboratories that require the highest precision across an extended mass spectrum. Encompassing 1 milligram to 200 grams with ASTM Class 1 tolerances, this 23-piece set is engineered for metrology applications, stringent quality assurance, and as a primary reference for calibrating secondary working standards.

Key Features & Advantages:

• Elite ASTM Class 1 Precision Across 200g: Delivers the tightest permissible tolerances over a wide range, making it suitable for calibrating high-accuracy analytical and precision balances, and for use in laboratories where measurement uncertainty budgets are critically minimized.

• Enhanced Metrological Properties: Features superior specifications, including lower magnetic susceptibility (X ≤ 0.03) and controlled density, ensuring minimal influence from environmental factors and providing reliable performance in precision measurement systems.

• Robotic Production for Guaranteed Consistency: Manufactured using automated robotic systems, each weight is produced to exacting standards, ensuring inherent accuracy and uniformity ideal for establishing or verifying a laboratory's internal calibration hierarchy.

• Sealed Cavity Construction for Ultimate Stability: The sealed adjusting cavity design protects against contamination and corrosion, ensuring the long-term mass stability required for reference standards that may see prolonged use between calibrations.

• Ideal Master Set for Accredited Calibration Labs: Provides a cost-effective solution for accredited laboratories to acquire top-tier reference masses without the immediate need for a certificate, allowing for in-house or third-party certification aligned with specific accreditation requirements.
