Overview
The A&D FX-iWP Series Waterproof Precision Electronic Balance is an industrial-grade analytical and precision balance engineered for high-reliability operation in demanding laboratory, quality control, and production environments. Utilizing A&D’s proprietary Super Hybrid Sensor (SHS) technology, the FX-iWP delivers rapid stabilization—typically within one second—while maintaining exceptional repeatability and linearity across its full capacity range (122 g to 3200 g). Designed for rigorous daily use, the balance integrates robust mechanical architecture with IP65-rated ingress protection, enabling reliable performance in humid, dusty, or spill-prone settings—including wet chemistry labs, pharmaceutical manufacturing suites, and food processing lines where liquid or powder samples are routinely handled. Its core measurement principle relies on electromagnetic force restoration (EMFR), ensuring long-term stability, minimal drift, and traceable calibration performance compliant with international metrological standards.
Key Features
- Rapid stabilization (≤1 s) enabled by A&D’s patented SHS sensor architecture, minimizing throughput bottlenecks in high-volume QC workflows.
- IP65-certified enclosure provides full protection against dust ingress and low-pressure water jets—validated per IEC 60529—making it suitable for washdown environments and routine cleaning with damp cloths or mild disinfectants.
- B5-form-factor footprint (approx. 250 × 180 mm) optimizes bench space while supporting integration into automated weighing stations and conveyor-linked inspection systems.
- Large fluorescent LCD display with high-contrast digits ensures legibility under variable lighting conditions, including low-illumination cleanrooms or brightly lit production floors.
- Integrated multi-directional shock absorption system mitigates mechanical vibration from adjacent equipment (e.g., mixers, compressors), preserving sensor integrity and extending service life.
- Full digital calibration capability supports user-input correction factors for certified reference weights—enabling traceable, documented adjustments without external service tools.
- ACAI (Automatic Counting Accuracy Improvement) algorithm dynamically compensates for particle size distribution variance during piece counting, reducing relative counting error by up to 40% compared to conventional methods.
- Built-in rechargeable battery (up to 12 hours continuous operation) ensures uninterrupted functionality during power fluctuations or mobile deployment scenarios.
Sample Compatibility & Compliance
The FX-iWP accommodates a broad spectrum of sample types—including hygroscopic powders, viscous liquids, granular solids, and live biological specimens—thanks to its below-hook weighing capability, optional draft shield compatibility, and animal weighing mode with dynamic averaging. All models support GLP/GMP-compliant data handling: each weight record can be tagged with operator ID, sample ID, timestamp, balance serial number, and calibration status. Audit trails meet FDA 21 CFR Part 11 requirements when paired with A&D’s optional WinCT software, which logs all parameter changes, calibration events, and weighing sessions with immutable timestamps and user authentication. The balance conforms to ISO 9001, ISO/IEC 17025, USP , and ASTM E1223–22 for precision mass measurement instrumentation.
Software & Data Management
Data export is supported via RS-232 and USB interfaces (virtual COM port), enabling seamless integration with LIMS, MES, and ERP platforms. WinCT software (Windows-based) provides real-time graphing, statistical analysis (mean, SD, CV%, min/max), batch reporting, and customizable certificate generation—including calibration reports with uncertainty budgets traceable to NMI-Japan (National Metrology Institute of Japan). All stored records include metadata required for regulatory audits: instrument configuration history, environmental condition tags (optional external sensor input), and electronic signatures for critical operations. Internal memory retains up to 2,000 weighing records with time/date stamps—even during power loss—ensuring continuity of compliance documentation.
Applications
- Pharmaceutical formulation: active ingredient dispensing, excipient ratio verification, and tablet weight uniformity testing per USP .
- Chemical R&D: precise reagent dosing for catalytic reactions and stoichiometric synthesis where ±0.1 mg accuracy is essential.
- Food & beverage QA: moisture content determination (via loss-on-drying protocols), ingredient batching, and net weight compliance checks for retail packaging.
- Materials science: density determination using Archimedes’ principle with the optional lower hook and sinker assembly.
- Clinical diagnostics: preparation of standardized assay reagents and calibration standards under CLIA-regulated workflows.
- Electronics manufacturing: component counting for SMT line replenishment and solder paste mass verification prior to stencil printing.
FAQ
What does IP65 rating mean for this balance?
IP65 indicates complete protection against dust (6) and resistance to low-pressure water jets from any direction (5), permitting safe operation in non-submersible wet environments.
Can the FX-iWP be calibrated internally without external weights?
No—internal calibration requires a certified reference weight; however, the full digital calibration interface allows entry of certified correction values for enhanced traceability.
Is the balance compatible with FDA 21 CFR Part 11 requirements?
Yes—when used with WinCT software and configured with user authentication, electronic signatures, and audit trail logging, it satisfies electronic record and signature provisions.
Does the ACAI function require special training or setup?
No—ACAI activates automatically during counting mode and adapts in real time based on sample mass distribution; no user intervention is needed.
How is overload protection implemented mechanically?
A multi-stage damping system—comprising elastomeric isolators and guided linear suspension—limits displacement of the load receptor during impact or accidental overloading, preventing sensor damage and eliminating need for recalibration after minor incidents.
