Product Description
The METTLER TOLEDO Vacuum Mass Comparator (M_one and M_10 models) represents the pinnacle of mass metrology, delivering the highest possible accuracy for primary weight calibration. These automated systems combine a ultra-high-resolution comparator (0.1 µg / 1 µg readability) with an automated weight handler inside a controlled vacuum chamber, eliminating air buoyancy effects. Designed for National Metrology Institutes and advanced calibration laboratories, they provide assured traceability and the lowest possible measurement uncertainty for artifacts from 1 mg up to 10 kg.
Key Features & Advantages:
Nanogram Precision in Controlled Vacuum: Performs mass determinations under controlled environmental conditions, from ambient pressure down to 10 { v mbar, to eliminate air buoyancy—the primary source of uncertainty—enabling mass calibration with accuracy down to 100 nanograms.
Fully Automated, Contamination-Free Operation: The integrated Artefact Storage and Transfer Vessel (ASTV) and Load Lock system allow for the transfer of weights into the weighing chamber without exposure to ambient air, ensuring artifact stability and preventing contamination.
Modular & Flexible System Design: Built on a modular basis, the system can be configured initially with core components (like the M_one comparator and vacuum chamber) and later expanded with additional automation (Load Lock, ATD) as application needs and budget evolve.
Accommodates Diverse Artefacts: Features a unique STAR-shaped weighing pan and Automated Gravimetric Centering (AGC) to handle various artifacts, including OIML weights (1 mg – 1 kg / 1 kg – 10 kg), silicon spheres (up to 100 mm), and density artifacts, positioning them precisely for minimal eccentricity error.
Comprehensive M_Control Software Suite: The dedicated M_Control software provides complete control over calibration processes, automated sequencing, data acquisition, and post-processing for air buoyancy compensation, ensuring full data integrity and streamlined operation for compliance with highest standards.
