METTLER TOLEDO MA2002 Precision Balance

Overview

The METTLER TOLEDO MA2002 Precision Balance is an entry-level analytical-grade weighing instrument engineered for routine laboratory and quality control environments where reproducibility, ergonomic operation, and regulatory traceability are essential. Utilizing electromagnetic force compensation (EMFC) technology, the MA2002 delivers stable, drift-resistant measurements under variable ambient conditions—including minor air currents and temperature fluctuations common in non-climate-controlled labs. Its 2,000 g capacity and 0.01 g readability meet the performance requirements of standard pharmacopeial assays (e.g., USP , EP 2.1.6), material formulation checks, sample preparation, and educational applications. Designed for high-throughput workflows, the balance integrates seamlessly into documented processes without requiring specialized training—making it suitable for multi-user facilities operating under GLP or GMP frameworks.

Key Features

• Electromagnetic force compensation (EMFC) sensor architecture ensures long-term stability and minimal warm-up time (<5 minutes to full specification).
• Internal automatic calibration system with integrated test weight performs routine recalibration at user-defined intervals or upon environmental trigger (e.g., ±1.5 °C change), maintaining metrological integrity between external verifications.
• High-contrast graphical LCD display (128 × 64 pixels) with intuitive icon-driven navigation and on-screen step-by-step guidance for common tasks (e.g., tare, percentage weighing, density determination).
• Sealed glass weighing pan and chemically resistant stainless-steel housing enable rapid decontamination and compliance with hygiene-critical environments (e.g., pharmaceutical QC labs).
• Touch-sensitive front-panel keys with tactile feedback reduce operational errors and support glove-compatible use.
• Dual communication interfaces—RS232 for legacy printers and LIMS integration, plus USB-A for direct connection to PCs, USB flash drives, or barcode scanners—facilitate audit-ready data export without middleware.

Sample Compatibility & Compliance

The MA2002 accommodates a wide range of sample types including powders, granules, liquids in containers, and small solid components. Its draft shield compatibility (optional accessory) extends usability to low-mass samples (<10 g) requiring enhanced environmental isolation. The balance conforms to international metrological standards including OIML R76-1 (Class II accuracy), ISO 9001 calibration traceability pathways, and supports full GLP documentation when paired with METTLER TOLEDO LabX Lite software (sold separately). Internal audit trail logging—enabled via firmware update—records operator ID, timestamp, net/gross/tare values, and calibration events, satisfying FDA 21 CFR Part 11 requirements for electronic records and signatures.

Software & Data Management

While the MA2002 operates autonomously via its embedded firmware, it is fully interoperable with METTLER TOLEDO’s LabX Lite software suite for centralized device management, method template deployment, and automated report generation. Data export formats include CSV, TXT, and XML—structured to align with LIMS ingestion protocols. USB-A port functionality enables direct saving of measurement logs onto removable media in real time, eliminating manual transcription and reducing transcription error risk by >92% (per internal METTLER TOLEDO validation study MA-2022-047). All data transmissions are unidirectional and non-editable at the device level, preserving raw result integrity.

Applications

• Pharmaceutical: Excipient dispensing, tablet weight uniformity testing per USP , and reference standard preparation.
• Academic & Research Labs: General chemistry lab instruction, stoichiometric reagent weighing, and calibration standard verification.
• Food & Beverage QC: Batch ingredient dosing, moisture content pre/post-drying mass determination, and package net weight verification.
• Materials Science: Powder blending ratio validation, catalyst loading quantification, and composite material density profiling.
• Environmental Testing Labs: Filter paper mass before/after particulate collection (EPA Method 201A, ISO 12103-1).

FAQ

What is the recommended recalibration frequency for the MA2002 in a regulated environment?
Internal calibration should be performed at startup, after significant ambient temperature shifts (>1.5 °C), and prior to critical measurements. External verification using NIST-traceable weights is advised daily or per SOP—typically aligned with shift changes in continuous-operation settings.
Does the MA2002 support direct printing to label printers?
Yes—via RS232, the balance outputs ASCII-formatted weight data compatible with Zebra, SATO, and Brady industrial label printers when configured with appropriate print templates.
Can the MA2002 store user-defined methods?
No—method storage requires LabX Lite or higher-tier software; however, the onboard interface retains last-used settings (e.g., unit, decimal places, auto-tare delay) across power cycles.
Is the glass weighing pan replaceable without service technician intervention?
Yes—the pan assembly is tool-free and field-replaceable using the included alignment jig, with full recalibration retained post-installation.
What is the maximum permissible load for dynamic weighing (e.g., filling operations)?
The MA2002 is rated for static weighing only; dynamic or off-center loading may compromise accuracy and void warranty coverage per METTLER TOLEDO Technical Bulletin TB-MA-012.
