Product Description
The METTLER TOLEDO 1g E0 class knob weight is a premium, one-piece (monobloc) reference standard, individually calibrated at a national metrology institute. Manufactured from vacuum-melted steel for exceptional purity and stability, this weight sets the benchmark for precision, providing the highest level of accuracy and traceability for calibrating analytical and precision balances.

Key Features & Advantages:

• Supreme E0 Accuracy Classification: Exceeds OIML E1 class tolerances, offering the highest achievable accuracy for a 1g weight and serving as a definitive primary standard for national and accredited calibration laboratories.

• Vacuum-Melted Steel for Ultimate Stability: Fabricated from high-grade steel refined through vacuum melting to eliminate trace elements, ensuring unparalleled long-term mass stability and corrosion resistance for the most demanding metrological applications.

• National Institute Calibration & Certificate: Individually finished and calibrated by a national metrology institute, providing the highest echelon of documented traceability through an authoritative calibration certificate.

• Monobloc Knob Design: Engineered as a one-piece (monobloc) knob weight, offering superior handling, durability, and geometric integrity compared to multi-piece constructions, minimizing potential for contamination or damage.

• Precise Density and Low Magnetism: Manufactured to exact density (8000 ±30 kg/m³) and low magnetic susceptibility (<0.02) specifications, enabling accurate air buoyancy corrections and reliable performance in sensitive measurement environments.
