METTLER TOLEDO MA6002 Precision Balance

Overview

The METTLER TOLEDO MA6002 Precision Balance is an entry-level analytical-grade weighing instrument engineered for routine laboratory and quality control applications requiring consistent accuracy, operational robustness, and regulatory traceability. Based on electromagnetic force compensation (EMFC) transduction technology, the MA6002 delivers stable, drift-compensated measurements across fluctuating ambient conditions—critical for environments where temperature gradients, air currents, or vibration may affect conventional strain-gauge systems. With a maximum capacity of 6,200 g and readability of 10 mg, it bridges the performance gap between basic top-loading balances and high-end analytical instruments—making it ideal for sample preparation, formulation, check-weighing, and intermediate-stage QC testing in pharmaceutical, chemical, food, and academic laboratories.

Key Features

• Electromagnetic force compensation (EMFC) sensor architecture ensures long-term stability, minimal warm-up time (< 30 minutes), and immunity to mechanical hysteresis.
• Automatic internal calibration triggered by time intervals, temperature shifts (>1.5 °C), or manual initiation—executed using a factory-certified internal test weight traceable to NIST standards.
• High-contrast graphical LCD display with intuitive icon-driven navigation; on-screen step-by-step guidance for common workflows including percentage weighing, density determination, and net/gross/tare operations.
• Integrated application library enables one-touch execution of 12 preprogrammed functions—including statistical batch weighing, parts counting, and formulation mode—with real-time deviation alerts.
• Dual-interface connectivity: RS232 supports legacy printers and LIMS integration; USB-A port allows direct connection to PCs, USB flash drives (FAT32 formatted), or barcode scanners without driver installation.
• IP54-rated enclosure with stainless steel weighing pan and optional removable glass draft shield—designed for resistance to dust ingress and accidental liquid splashes during routine cleaning.

Sample Compatibility & Compliance

The MA6002 accommodates samples up to 6.2 kg with dimensions compatible with standard laboratory containers (e.g., beakers up to Ø180 mm × H150 mm). Its open-frame design permits rapid placement and removal of vessels, while the low-profile pan geometry minimizes center-of-gravity instability during dynamic loading. The balance meets ISO 9001 and ISO/IEC 17025 requirements for measurement uncertainty management and is validated for use in GLP and GMP environments when operated with documented procedures. Data output complies with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) and supports FDA 21 CFR Part 11 compliance when paired with METTLER TOLEDO LabX™ software (sold separately), enabling electronic signatures, audit trails, and role-based access control.

Software & Data Management

Raw weighing data are transmitted in ASCII format via RS232 or USB virtual COM port, ensuring compatibility with Excel, LabWare LIMS, and custom SCADA systems. Optional LabX™ software transforms the MA6002 into a networked, compliant workstation: automatic metadata capture (operator ID, timestamp, location), configurable report templates (PDF/CSV), and encrypted database storage with full revision history. All data transfers include checksum validation and timestamped log files—essential for audit readiness and root-cause analysis during regulatory inspections.

Applications

• Pharmaceutical: Raw material receipt verification, excipient dispensing, tablet weight uniformity checks per USP .
• Chemical manufacturing: Batch ingredient dosing, catalyst charge verification, and reaction stoichiometry support.
• Food & beverage: Portion control validation, nutritional labeling mass assignments, and HACCP critical control point monitoring.
• Academic research: Teaching labs for metrology fundamentals, environmental sample quantification (e.g., soil moisture loss), and polymer blend ratio verification.
• Industrial QA: Component count verification, packaging fill-weight audits, and incoming inspection of machined parts.

FAQ

What is the typical repeatability specification for the MA6002 at full load?
Repeatability is ≤ ±0.02 g (2σ) under controlled lab conditions (20 ±2 °C, <50% RH, no drafts), verified per OIML R76-1 Annex C.
Does the MA6002 support external calibration with user-provided weights?
Yes—external calibration is available via menu-driven procedure using Class M2 or better certified weights; however, internal calibration remains the recommended method for routine operation.
Can the balance store weighing records locally without external software?
No—the MA6002 does not feature onboard memory; all data must be transmitted in real time or logged externally via connected devices.
Is the RS232 interface opto-isolated?
Yes—RS232 communication employs galvanic isolation to prevent ground-loop interference in electrically noisy production environments.
What is the warm-up time required before first-use calibration?
Minimum 30 minutes at stable ambient temperature; calibration is automatically reinitiated if internal temperature drift exceeds ±1.5 °C post-warm-up.
