METTLER TOLEDO MA602P Compact Laboratory Balance

Overview

The METTLER TOLEDO MA602P Compact Laboratory Balance is an entry-level analytical-grade weighing instrument engineered for precision, portability, and operational consistency in non-regulated and light-duty regulated environments. Utilizing electromagnetic force restoration (EMFR) technology, the MA602P delivers stable, drift-compensated measurements with high reproducibility across variable ambient conditions. Its compact footprint (under 200 mm wide) and lightweight design (approximately 1.8 kg) enable seamless relocation between workbenches, field laboratories, teaching labs, and quality control stations—without compromising mechanical stability or metrological integrity. The balance operates on dual power sources: a standard AC adapter for continuous benchtop use or an integrated rechargeable battery for up to 8 hours of uninterrupted operation—making it suitable for mobile applications such as inventory audits, raw material verification at receiving docks, or educational demonstrations outside dedicated lab spaces.

Key Features

• Electromagnetic force restoration (EMFR) sensor architecture ensures fast stabilization time (<2 seconds) and minimal temperature-induced drift.
• High-contrast backlit LCD display with large, legible digits (18 mm height) and contextual on-screen prompts for step-by-step weighing guidance.
• Touch-sensitive front-panel keys with tactile feedback simplify menu navigation, unit selection (g, mg, oz, ct), and application mode activation (e.g., parts counting, percentage weighing, density determination).
• Integrated internal calibration system: One-touch initiation triggers automatic calibration using a factory-mounted test weight; traceable to national standards and compliant with ISO 9001 internal audit requirements.
• Durable construction featuring chemically resistant glass top plate, reinforced ABS housing, and IP42-rated enclosure for protection against dust ingress and incidental splashes.
• USB interface supports direct connection to PCs or printers for real-time data export; compatible with METTLER TOLEDO’s LabX Lite software for basic result logging and report generation.

Sample Compatibility & Compliance

The MA602P accommodates standard laboratory sample containers—including weighing boats, beakers, crucibles, and vials—within its 200 mm diameter pan area. Its overload protection (up to 150% of max capacity) and shock-absorbing pan suspension minimize risk of sensor damage during routine handling. While not certified for USP or ASTM E898-22 Class I applications, the balance meets ISO/IEC 17025 general-purpose testing requirements when used within its specified environmental operating range (10–30 °C, ≤80% RH non-condensing). Its firmware supports user-defined audit trails for calibration events and critical parameter changes, facilitating adherence to GLP documentation practices and internal quality system reviews.

Software & Data Management

Data capture is supported via USB virtual COM port protocol, enabling seamless integration with spreadsheet applications or LIMS via ASCII text streaming. Optional LabX Lite software provides configurable templates for batch reporting, automatic timestamping, and electronic signature fields—sufficient for ISO 9001 Clause 8.5.2 records retention. All calibration logs include date/time stamps, operator ID (manually entered), and deviation values relative to last verified reference point. No cloud connectivity or FDA 21 CFR Part 11 compliance is implemented; however, local file exports (.csv, .txt) are fully auditable and tamper-evident when stored on secured network drives.

Applications

• Teaching laboratories: Ideal for undergraduate chemistry and biology courses requiring reliable mass measurement without complex setup.
• Production line checks: Rapid verification of component weights, packaging fill levels, or additive dosing prior to batch release.
• Field-based QC: On-site raw material inspection in warehouses or distribution centers where fixed infrastructure is unavailable.
• Pharmaceutical pre-formulation: Preliminary excipient weighing during early-stage development where full GMP-grade instrumentation is not mandated.
• Maintenance workshops: Calibration verification of torque wrenches, pipettes, or other tools requiring traceable mass references.

FAQ

What is the maximum weighing capacity and readability of the MA602P?
The MA602P offers a 600 g capacity with 0.01 g readability (10 mg resolution), optimized for general-purpose laboratory tasks requiring moderate precision.
Does the MA602P support external calibration with user-provided weights?
No—it is equipped exclusively with internal automatic calibration; external calibration is not supported by design.
Can the balance operate continuously on battery power?
Yes, the integrated rechargeable battery provides approximately 8 hours of typical usage between charges, with low-battery warnings displayed 30 minutes prior to shutdown.
Is the MA602P suitable for use in a fume hood?
It may be used inside a fume hood only if airflow velocity remains below 0.5 m/s and the unit is placed on a vibration-dampened surface; otherwise, air currents will degrade repeatability.
What documentation is provided for quality assurance purposes?
Each unit ships with a factory-issued conformity statement, calibration certificate (traceable to NIM, China), and user manual compliant with IEC 61000-6-3 EMC standards.
