AND FX-200i Precision Analytical Balance (220 g capacity, 1 mg readability)

Overview

The AND FX-200i is a high-precision analytical balance engineered for trace-level mass measurement in controlled laboratory and production environments—particularly where microgram-level repeatability and ISO/IEC 17025-compliant weighing integrity are required. Designed and manufactured in Japan under strict AND quality assurance protocols, the FX-200i employs electromagnetic force compensation (EMFC) technology to deliver stable, drift-resistant measurements across fluctuating ambient conditions. Its 220 g maximum capacity and 1 mg minimum readability meet the stringent demands of printed electronics manufacturing, including precise dispensing of conductive inks, nanoparticle suspensions, and functional polymer formulations used in semiconductor component printing. The compact B5 footprint (193 × 262.5 mm) enables seamless integration onto cleanroom workbenches or inline QC stations without compromising stability or metrological performance.

Key Features

• Electromagnetic force compensation sensor with automatic internal calibration verification at power-on and user-initiated intervals
• Three-step selectable display update rate (5 / 10 / 20 Hz) optimized for dynamic weighing tasks such as real-time ink formulation monitoring or gravimetric dosing
• SUS304 stainless-steel weighing pan (φ130 mm) resistant to chemical corrosion from solvents commonly used in printed electronics processing (e.g., terpineol, ethyl cellulose, DMSO)
• Multi-unit support: g, %, carat, and monme—enabling direct compatibility with legacy Japanese gemological and traditional material specifications
• RS-232C serial interface (D-sub 9-pin male) compliant with ANSI/TIA-232-F standards, enabling bidirectional communication with WinCT software and LIMS systems
• Integrated draft shield and protective cover included—designed to minimize air-current-induced noise during low-mass measurements (<10 mg)
• Low-power architecture (~11 VA total system draw) suitable for continuous operation in energy-constrained cleanroom utility grids

Sample Compatibility & Compliance

The FX-200i accommodates heterogeneous samples typical in printed electronics R&D and pilot-line production: viscous conductive pastes (e.g., Ag, Cu, Ni nanoparticle inks), low-surface-tension solvent blends, and hygroscopic polymer precursors. Its sealed sensor housing and non-porous pan surface mitigate moisture absorption and particulate adhesion—critical when handling sub-10 mg aliquots of functional materials. The instrument conforms to JIS B 7721 Class I accuracy requirements for analytical balances and supports GLP/GMP documentation workflows via WinCT’s audit-trail-enabled data export (CSV, TXT). While not FDA 21 CFR Part 11–certified out-of-the-box, its deterministic RS-232 output and timestamped weight logs enable validation-ready integration into regulated environments under client-defined SOPs.

Software & Data Management

WinCT software (Windows-compatible, included) provides full remote control, statistical analysis (mean, SD, CV%, min/max), and automated report generation. Raw weight data—including time stamps, unit selection, and environmental metadata (if connected to optional temperature/humidity sensors)—is logged with immutable file attributes. Export formats comply with ASTM E1482-22 (Standard Guide for Data Exchange in Laboratory Information Systems), facilitating traceable data migration into enterprise QMS platforms. All communications adhere to standard ASCII protocol framing; no proprietary drivers or cloud dependencies are required—ensuring long-term data sovereignty and offline operability.

Applications

• Gravimetric formulation of conductive inks prior to screen or inkjet deposition on flexible substrates
• Mass verification of deposited layers after thermal sintering (e.g., post-annealing silver trace mass loss quantification)
• In-process QC of semiconductor packaging adhesives and underfill materials
• Calibration of micro-dosing pumps using reference-standard weight gain methodology (per ISO 8655-5)
• Stability testing of nanomaterial dispersions via repeated 5–50 mg aliquot weighing over 24-hr periods
• Teaching and method development in university thin-film electronics labs requiring NIST-traceable mass metrology

FAQ

Is the FX-200i suitable for use in ISO Class 5 cleanrooms?
Yes—the unit’s sealed electronics, absence of internal fans, and smooth SUS304 surfaces support routine ISO 14644-1 compliant cleaning with IPA wipes and static-dissipative lint-free cloths.
Does it support internal calibration with external weights?
No—the FX-200i uses factory-programmed internal calibration; external calibration requires third-party accredited weights and documented adjustment procedures per ISO/IEC 17025 Clause 6.5.
Can WinCT log data directly to a network drive?
Yes—provided Windows permissions and UNC path accessibility are configured; WinCT writes files using standard file I/O without requiring database services.
What is the warm-up time to achieve rated repeatability?
Less than 30 minutes after power-on at 23 ±2 °C ambient; full specification performance is guaranteed after 60 minutes per JIS B 7721 Annex B.
Is the RS-232 interface optically isolated?
No—galvanic isolation is not built-in; for electrically noisy production floors, use an externally powered RS-232 isolator (e.g., ADUM1201-based module) compliant with IEC 61000-4-5 surge immunity.
