Overview
The Sartorius CCE Series Automatic Mass Comparator is a high-precision metrological instrument engineered for traceable mass calibration and intercomparison in national metrology institutes, accredited calibration laboratories, and primary standards labs. Operating on the principle of electromagnetic force compensation (EMFC), it delivers direct, drift-compensated mass measurement by balancing gravitational force against a precisely controlled electromagnetic force—eliminating mechanical wear and enabling long-term stability. Unlike manual or semi-automated comparators, the CCE series integrates a motorized load alternator that automatically sequences reference standards and test weights without operator intervention, ensuring consistent loading geometry, minimized thermal drift, and full compliance with OIML R 111 and ISO/IEC 17025 requirements for uncertainty budgeting. Designed and manufactured in Germany, each unit undergoes individual factory calibration traceable to the PTB (Physikalisch-Technische Bundesanstalt) and includes a full metrological certificate.
Key Features
- Integrated load alternator with bidirectional robotic arm for fully automated handling of reference masses and unknowns—no manual placement, no stack-dependent errors
- Electromagnetic force compensation transducer with active temperature stabilization and real-time drift correction
- Hermetically sealed weighing chamber with dual-layer glass doors, internal vibration damping, and optional air purge interface for inert atmosphere operation
- Modular design supporting multiple configurations: CCE1000S-L (1 kg, 1 µg readability), CCE10000U-L (10 kg, 0.01 mg), CCE10000S-L (10 kg, 0.1 mg), CCE20000S-L (20 kg, 0.1 mg), and CCE50001S-L (51 kg, 1 mg)
- Compliance with OIML R 111 Class E1/E2 weight handling protocols—including automatic density correction, buoyancy compensation, and air density monitoring via integrated sensors
- IP54-rated electronics housing with galvanically isolated RS-232, Ethernet, and USB interfaces for secure lab network integration
Sample Compatibility & Compliance
The CCE series accommodates standard cylindrical, hexagonal, and rectangular weights conforming to OIML R 111 geometries—from 1 mg to 50 kg—and supports both single-piece and multi-piece weight sets. It is certified for use in E1- and E2-class calibration workflows per OIML R 111-1:2023 and meets the environmental and procedural requirements of ISO/IEC 17025:2017 Clause 6.4 (Equipment) and Clause 7.7 (Uncertainty of Measurement). All firmware and control logic are validated under GLP-compliant development practices; audit trails, user access logs, and electronic signatures align with FDA 21 CFR Part 11 when paired with Sartorius LabX software. The system is routinely deployed in NMIs across Europe and Asia for maintaining national mass standards and supporting BIPM key comparisons.
Software & Data Management
Controlled via Sartorius LabX Mass Calibration Software (v4.0+), the CCE series enables protocol-driven calibration sequences—including substitution, ABBA, and Borda methods—with configurable uncertainty propagation per GUM (JCGM 100:2008). LabX provides full 21 CFR Part 11 compliance: role-based user permissions, immutable electronic records, digital signature capture, and time-stamped audit trails for every weighing cycle, parameter change, or report generation. Raw data export supports CSV, XML, and PDF formats; metadata includes ambient temperature, pressure, humidity, air density, and transducer status. Optional integration with LIMS and ERP systems is supported via RESTful API and OPC UA connectivity.
Applications
- Primary and secondary mass calibration in national metrology institutes (NMIs) and designated institutes (DIs)
- Periodic verification and recalibration of E1/E2 reference weights used in pharmaceutical QC labs and aerospace manufacturing
- Interlaboratory comparison studies under CIPM MRA frameworks
- Development and validation of mass standards for semiconductor wafer handling and microfabrication tool calibration
- Uncertainty analysis support for ISO/IEC 17025 accreditation audits in calibration laboratories
- Traceable mass transfer between kilogram prototypes and working standards in research institutions
FAQ
What OIML weight classes can the CCE series calibrate?
The CCE series is validated for E1-, E2-, and F1-class weight calibration up to 51 kg, with full support for OIML R 111 geometric tolerances and material-specific density corrections.
Does the system require external environmental monitoring?
No—integrated high-accuracy sensors continuously measure temperature (±0.05 °C), atmospheric pressure (±0.1 hPa), and relative humidity (±1 %RH) for real-time air density calculation and buoyancy correction.
Can the CCE operate in a cleanroom environment?
Yes—the CCE20000S-L and CCE50001S-L models are optionally available with ISO Class 5-compatible enclosures and HEPA-filtered air purge ports.
Is remote operation and monitoring supported?
Yes—LabX software enables secure remote access via TLS-encrypted web client, allowing supervised calibration sessions and live data review from offsite locations.
How is traceability maintained during firmware updates?
Each firmware release is version-controlled, digitally signed, and accompanied by a metrological impact assessment; update logs are retained in the system’s audit trail and included in calibration certificates.
