METTLER TOLEDO MA3002/A Precision Balance

Overview

The METTLER TOLEDO MA3002/A Precision Balance is an industrial-grade analytical weighing instrument engineered for high reproducibility and operational robustness in regulated laboratory, quality control, and production environments. Built upon METTLER TOLEDO’s proven electromagnetic force compensation (EMFC) transduction principle, the MA3002/A delivers stable, drift-resistant measurements across its full 3.2 kg capacity range with a certified readability of 0.01 g. Its design prioritizes metrological integrity: the internal calibration system employs a built-in reference mass to automatically compensate for thermal drift and mechanical hysteresis—ensuring traceable accuracy without external weights. The balance meets essential regulatory benchmarks including USP Chapter 41 (Balance Performance Verification), USP Chapter 1251 (Weighing on Analytical Balances), and supports ISO/IEC 17025-compliant calibration documentation workflows. With an IP43-rated enclosure, it resists dust ingress and light splashing—making it suitable for shared lab spaces where routine cleaning with mild solvents is required.

Key Features

• Electromagnetic force compensation (EMFC) sensor architecture for long-term stability and low noise performance
• Internal automatic calibration triggered via single-touch interface—no manual weight handling required
• Backlit LCD touchscreen with intuitive icon-driven navigation and context-sensitive prompts
• Robust metal base and chemically resistant housing compatible with common laboratory cleaning agents (e.g., 70% ethanol, isopropanol)
• Configurable auto-standby mode with programmable timeout (1–60 minutes); zero warm-up delay upon wake-up
• Password-protected settings access to prevent unauthorized configuration changes—supports multi-user environments with consistent parameter enforcement
• Real-time repeatability monitoring: typical standard deviation ≤ 7 mg under controlled ambient conditions (20 ± 2 °C, <50% RH, draft-free)

Sample Compatibility & Compliance

The MA3002/A accommodates diverse sample forms—including powders, granules, liquids in tared containers, and solid components up to 180 mm × 180 mm footprint—without compromising resolution or linearity. Its 1.4 g minimum weight (U = 1%, k = 2) and 14 g minimum weight (USP <0.1% tolerance, k = 2) are validated per USP General Chapter 1251 guidelines. The balance complies with OIML R76-1 (Class II) for trade-related applications and supports GLP/GMP audit trails when integrated with METTLER TOLEDO LabX software. All firmware and calibration logs retain time-stamped metadata, satisfying FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed with appropriate system validation.

Software & Data Management

Data export is streamlined via dual serial protocols: RS232 enables direct printing to ESC/POS-compatible label or receipt printers, while USB-A supports plug-and-play connection to Windows/macOS PCs or FAT32-formatted USB flash drives for batch data archiving. When paired with METTLER TOLEDO LabX software (sold separately), the MA3002/A enables automated report generation, user-defined calculation templates (e.g., % loss-on-drying, net/gross/tare), and centralized instrument management across multi-balance networks. Audit trail functionality captures operator ID, timestamp, weight value, and event type (e.g., calibration, tare, print) with immutable digital signing—fully aligned with ALCOA+ data integrity principles.

Applications

This precision balance serves critical functions across pharmaceutical formulation (active ingredient dispensing, excipient blending), chemical R&D (catalyst dosing, reaction stoichiometry), food quality assurance (moisture content verification, recipe compliance), and academic teaching labs (density determination, gravimetric analysis). Its rapid 1-second stabilization time supports high-throughput workflows such as tablet weight checks in QC release testing. The IP43 rating and corrosion-resistant construction also permit deployment in pilot-scale manufacturing areas where environmental controls are less stringent than Class A cleanrooms.

FAQ

What is the certified readability and maximum capacity of the MA3002/A?
The MA3002/A provides a certified readability of 0.01 g and a maximum capacity of 3.2 kg.
Does the balance support GLP/GMP-compliant data handling?
Yes—when used with LabX software and configured with user authentication, electronic signatures, and audit trail logging, it fulfills core FDA 21 CFR Part 11 and EU Annex 11 requirements.
Can the internal calibration be scheduled automatically?
No—the internal calibration is manually initiated via touchscreen; however, it can be performed at any time without external weights and completes within seconds.
Is the MA3002/A suitable for weighing volatile or static-prone samples?
Its draft shield compatibility (optional accessories available) and low-noise EMFC sensor mitigate air current interference; anti-static kits and ionizers may be added per application-specific risk assessment.
What regulatory standards does this model meet for pharmaceutical use?
It supports USP , , and EP 2.1.6 verification protocols; full compliance requires documented installation qualification (IQ), operational qualification (OQ), and periodic performance verification per site SOPs.
