Anden FX-iWP Series Waterproof Precision Electronic Balance

Overview

The Anden FX-iWP Series Waterproof Precision Electronic Balance is an industrial-grade analytical weighing instrument engineered for high-reproducibility mass measurement in demanding laboratory, quality control, and automated manufacturing environments. Utilizing Anden’s proprietary Strain-Hybrid Sensor (SHS) architecture, the FX-iWP achieves 1 mg readability with ≤1 second stabilization time—enabling rapid, repeatable measurements of solids, powders, and low-viscosity liquids without drift or thermal lag. Its fully sealed mechanical design meets IP65 ingress protection standards, ensuring reliable operation in humid, dusty, or splash-prone settings such as wet chemistry labs, pharmaceutical formulation areas, food processing lines, and cleanroom-adjacent QC stations. Unlike conventional electromagnetic force compensation (EMFC) balances, the SHS platform delivers enhanced mechanical robustness and long-term calibration stability under variable environmental loads—critical for applications requiring traceable, audit-ready data across regulatory workflows.

Key Features

• IP65-rated enclosure: Full protection against dust ingress and water jets from any direction—validated per IEC 60529—enabling safe use near sinks, wash stations, or solvent-handling zones.
• SHS sensor technology: Patented hybrid strain gauge architecture delivering 1 mg resolution with sub-second response, minimal creep, and immunity to minor floor vibrations.
• Vibration damping system: Integrated multi-axis shock absorption isolates the load cell from external mechanical disturbances, extending sensor service life and maintaining metrological integrity during high-throughput operations.
• Large fluorescent LCD display: High-contrast, wide-view-angle screen with adjustable brightness; supports dual-line readout (net weight + unit/statistic) for unambiguous operator interpretation.
• Digital calibration suite: Full internal calibration with user-input correction factors for certified test weights—eliminating mechanical adjustment and supporting ISO/IEC 17025-compliant uncertainty budgets.
• Regulatory-ready data handling: GLP/GMP-compliant print/export of balance ID, calibration history, date/time stamps, operator codes, and full audit trail metadata via RS-232 or USB interface.
• ACAI (Automatic Counting Accuracy Improvement): Dynamic algorithm that compensates for particle size distribution variance during piece counting—reducing statistical error by up to 40% versus fixed-threshold methods.
• Built-in rechargeable battery: Supports ≥12 hours continuous operation on single charge; auto-switches between AC and DC power with seamless transition and state-of-charge monitoring.

Sample Compatibility & Compliance

The FX-iWP accommodates a broad range of sample types—including hygroscopic powders, viscous suspensions, live biological specimens (via animal weighing mode), and small-volume liquid aliquots—without compromising repeatability. Its below-balance hook enables density determination of irregular solids using Archimedes’ principle, while the optional large draft shield (sold separately) satisfies ASTM E898-22 requirements for low-airflow static weighing environments. The balance conforms to international metrological standards including OIML R76-1 (2021), EN 45501:2015, and JIS B 7721-1:2020. All firmware and data export protocols support FDA 21 CFR Part 11 compliance when integrated with validated LIMS or ELN systems—ensuring electronic records are attributable, legible, contemporaneous, original, and accurate (ALCOA+ principles).

Software & Data Management

Data output is natively compatible with Windows-based laboratory software via standard ASCII protocol over RS-232 or virtual COM port (USB). Raw weight values, statistics (mean, SD, CV%), count totals, and percent deviation are timestamped and tagged with user-defined IDs. Optional Anden DataLink™ software provides real-time graphing, SPC chart generation (X-bar/R), and automated report templates aligned with ISO 9001 clause 7.6 and USP . All calibration events—including due dates, tolerance thresholds, and pass/fail status—are logged with immutable digital signatures. Internal memory retains ≥1,000 weight records with full metadata, accessible via direct USB export or remote query through serial command set (SCPI-compatible syntax).

Applications

• Pharmaceutical: Active ingredient dispensing, excipient blending verification, capsule fill weight checks, and reference standard preparation under GMP Annex 11 conditions.
• Chemical R&D: Catalyst dosage control, reaction stoichiometry validation, and gravimetric titration endpoint confirmation.
• Food & Beverage: Batch consistency auditing, nutritional labeling compliance (FDA 21 CFR 101), and HACCP critical control point monitoring.
• Academic Research: Teaching labs requiring rugged instrumentation for student use; materials science labs performing density and porosity analysis.
• Automated Manufacturing: Integration into pick-and-place workcells via programmable I/O (optional module) for closed-loop feedback in precision filling systems.

FAQ

Does the FX-iWP support external calibration with NIST-traceable weights?
Yes—the balance accepts user-defined calibration coefficients for Class M1 or better weights, with full documentation of correction values and uncertainty contributions per ISO/IEC 17025 Section 6.5.
Can the built-in battery be replaced in-field without service tools?
No—the Li-ion battery is user-serviceable only by authorized Anden technicians to maintain IP65 integrity and calibration traceability.
Is the RS-232 interface opto-isolated?
Yes—galvanic isolation prevents ground-loop interference in electrically noisy production environments.
What is the maximum permissible overload before sensor damage occurs?
The SHS sensor is rated for 150% of full scale for ≤10 seconds; sustained overloads >120% trigger audible and visual alerts and suspend measurement until reset.
Does the FX-iWP meet ISO 14001 energy efficiency criteria?
Its auto-power-off function (configurable 1–60 min idle timeout), low-quiescent-current design, and ENERGY STAR®-aligned standby consumption (<0.3 W) align with ISO 14001:2015 Annex A.3.3 energy performance indicators.
