Product Description
The METTLER TOLEDO 20g E0 class knob weight is an elite one-piece (monobloc) reference standard, calibrated at a national metrology institute. Manufactured from vacuum-melted steel for maximum purity and stability, it provides the highest level of accuracy and traceability, serving as a definitive primary standard for calibrating analytical and high-capacity precision balances in accredited and national standards laboratories.
Key Features & Advantages:
Ultimate E0 Metrological Class: Exceeds OIML E1 class tolerances, representing the highest order of accuracy for a 20g weight and establishing it as a primary reference for the most demanding calibration applications.
Vacuum-Melted Steel Construction: Fabricated from high-grade steel refined through vacuum melting, which eliminates trace elements to ensure exceptional long-term mass stability, corrosion resistance, and measurement reliability.
National Metrology Institute Certification: Individually finished and calibrated by a national institute, providing the highest level of documented metrological traceability through an authoritative calibration certificate.
Durable Monobloc Knob Design: Engineered as a robust, one-piece (monobloc) knob weight, offering superior handling characteristics, geometric integrity, and resistance to contamination or damage.
Precise Density and Low Magnetic Properties: Manufactured to exact specifications for density (8000 ±30 kg/m³) and magnetic susceptibility (<0.02), enabling accurate air buoyancy corrections and reliable performance in sensitive measurement environments.
