AND GX-8202M IP65 Dust- and Water-Resistant Precision Balance with Internal Calibration, 8.2 kg Capacity, 0.01 g Readability

Overview

The AND GX-8202M is an industrial-grade precision balance engineered for demanding production, quality control, and laboratory environments where environmental resilience and metrological reliability are non-negotiable. Designed and manufactured in Japan by A&D Co., Ltd. — a globally recognized leader in weighing instrumentation — the GX-8202M employs electromagnetic force restoration (EMFR) sensor technology to deliver stable, high-reproducibility measurements under dynamic operational conditions. Its IP65-rated enclosure ensures full protection against dust ingress and low-pressure water jets, enabling safe deployment in humid cleanrooms, wet-process lines, food processing zones, or chemical handling areas where splash exposure or airborne particulates would compromise conventional balances. With a maximum capacity of 8.2 kg and readability of 0.01 g, the GX-8202M bridges the gap between analytical and industrial weighing — supporting applications ranging from formulation verification and batch reconciliation to real-time mass flow monitoring.

Key Features

• IP65-rated robust housing: Sealed front panel, removable stainless-steel pan assembly (SUS316), and detachable rear chassis enable thorough cleaning and compliance with hygiene-critical standards (e.g., ISO 22000, FDA cGMP).
• Integrated internal calibration system: Motor-driven, traceable internal weight eliminates manual calibration drift and reduces operator dependency; calibration completes in ≤90 seconds without external masses.
• Intelligent shock detection (ISD): Four-stage visual alert + audible beep activates when mechanical impact exceeds predefined thresholds — protecting load cell integrity and preserving long-term accuracy during line-side mounting.
• Flow rate display (FRD): Real-time derivative calculation converts sequential mass readings into volumetric or gravimetric flow rates (e.g., g/s or mL/min), eliminating need for separate flow meters in pump calibration or dispensing validation.
• Electronic Control Load (ECL) algorithm: Continuously evaluates internal repeatability performance using proprietary statistical sampling; reports stability metrics and triggers recalibration alerts based on actual usage patterns — not fixed time intervals.
• Dual communication interface: Simultaneous RS-232C (D-Sub 9-pin male) and USB Mini-B outputs support legacy SPC systems and modern PC-based data acquisition software; configurable baud rates up to 115.2 kbps.

Sample Compatibility & Compliance

The GX-8202M accommodates diverse sample types — from powders and granules to viscous liquids and irregularly shaped components — thanks to its large 270 × 210 mm SUS316 pan and optional draft shield. The removable pan mount and shock-absorbing substructure minimize vibration transmission to the EMFR transducer, ensuring consistent results even on non-isolated workbenches. Regulatory alignment includes conformity with OIML R76-1 (2021), JIS B 7720-1:2020, and NIST Handbook 44 Class III requirements. Firmware supports audit trail logging per FDA 21 CFR Part 11 when connected to compliant LIMS or ELN platforms. Optional user authentication (PIN/password) and clock-synchronized timestamping fulfill GLP/GMP documentation mandates.

Software & Data Management

Data output adheres to standard ASCII protocols compatible with Microsoft Excel, LabWare LIMS, and custom Python/Matlab scripts via serial/USB virtual COM port. Built-in statistical functions include mean, SD, CV%, max/min, and tolerance checking with pass/fail flagging. Density measurement mode leverages air buoyancy correction per ASTM D792 and ISO 1183-1. All stored records (up to 1,000 entries) retain timestamps, operator IDs, and environmental flags (e.g., “ISD triggered”, “FRD active”). Exported CSV files include metadata headers compliant with ISO/IEC 17025 clause 7.7 traceability requirements.

Applications

• Gravimetric dosing verification in pharmaceutical tablet coating lines
• In-line mass flow monitoring for liquid filling machines (e.g., syrups, solvents)
• Raw material receipt inspection under ISO 9001 Clause 8.6
• Quality assurance testing of battery electrode slurries and ceramic pastes
• Calibration of peristaltic pumps using FRD-derived flow profiles
• Environmental lab sample preparation where washdown capability is required (e.g., wastewater solids analysis)

FAQ

Does the GX-8202M meet ISO/IEC 17025 calibration requirements?
Yes — when used with A&D’s certified internal calibration mass and validated procedures, it satisfies ISO/IEC 17025:2017 clause 6.5.2 for in-house verification; external periodic calibration by an accredited lab is still recommended annually.
Can FRD mode be used for regulatory submissions?
FRD provides indicative flow trends; for validated flow measurement, cross-correlation with primary standards (e.g., Coriolis meter) and documented uncertainty budgeting per GUM (JCGM 100:2008) is required.
Is the USB interface compatible with Windows 11 and macOS Ventura+
Yes — plug-and-play HID-compliant mode requires no driver installation; virtual COM port mode uses standard CDC ACM drivers included in both OS families.
What maintenance intervals are recommended for IP65 operation?
Visual inspection every 3 months; full pan and housing disassembly + ethanol wipe-down every 6 months; annual sensor diagnostics via A&D Service Mode (accessible via service PIN).
