Product Description
The METTLER TOLEDO 50g E0 class knob weight is a definitive one-piece (monobloc) reference standard, individually calibrated at a national metrology institute. Manufactured from vacuum-melted steel for exceptional purity and stability, it provides the highest level of accuracy and traceability, serving as an authoritative primary standard for calibrating analytical and high-capacity precision balances.

Key Features & Advantages:

• Peak Metrological Performance (E0 Class): Exceeds OIML E1 class tolerances, offering the highest achievable accuracy for a 50g weight and establishing it as a cornerstone standard for national and accredited calibration chains.

• Superior Vacuum-Melted Steel: Fabricated from high-grade steel refined through vacuum melting, ensuring exceptional purity, long-term mass stability, and corrosion resistance by eliminating undesirable trace elements.

• National Metrology Institute Certification: Each weight is individually finished and calibrated by a national institute, providing the highest echelon of documented traceability through an authoritative calibration certificate.

• Durable Monobloc Construction: Engineered as a robust, one-piece (monobloc) knob weight, offering superior handling, geometric integrity, and resistance to contamination compared to assembled weights.

• Exact Physical Properties: Manufactured to precise specifications for density (8000 ±30 kg/m³) and low magnetic susceptibility (<0.02), enabling accurate air buoyancy corrections and reliable performance in critical measurement applications.
