Overview
The ZiQi FA2204T is a Class I analytical balance engineered for precision mass measurement in regulated laboratory environments. Utilizing electromagnetic force compensation (EMFC) sensor technology, it delivers high reproducibility and long-term stability across its full 220 g capacity range. With a readability of 0.1 mg (1 × 10⁻⁴ g), the instrument satisfies the metrological requirements for quantitative analysis, formulation verification, and quality control procedures where sub-milligram resolution is essential. Its robust die-cast aluminum housing provides mechanical rigidity and electromagnetic shielding—critical for minimizing environmental interference in shared lab spaces or near RF-emitting equipment. Designed for compliance-driven workflows, the FA2204T supports audit-ready operation through traceable internal calibration, real-time stability monitoring, and hardware-level error detection.
Key Features
- Electromagnetic force compensation (EMFC) transducer ensures high linearity, low hysteresis, and minimal drift over time.
- 5-inch capacitive touchscreen interface with intuitive icon-based navigation—enabling rapid access to density determination, percentage weighing, and net/gross/tare functions without menu diving.
- Automatic internal calibration with user-configurable scheduling (e.g., at startup, after temperature shift >1.5°C, or at fixed intervals), eliminating manual weight handling and reducing calibration uncertainty.
- Full-range tare, cumulative weighing, overload/underload indication, and audible/visual fault alerts enhance operational safety and data integrity.
- Integrated RS-232 serial port enables direct connection to label printers, PCs, or LIMS systems; compatible with standard ASCII command protocols for seamless data export.
- Advanced weighing algorithms reduce stabilization time to ≤4 seconds—even under draft-sensitive conditions—improving throughput in high-volume QC labs.
Sample Compatibility & Compliance
The FA2204T accommodates standard Ø80 mm weighing pans and is compatible with common labware including weighing boats, crucibles, and sample vials. Its draft shield design (sold separately) meets ISO 17025 environmental recommendations for vibration- and airflow-controlled weighing stations. The balance conforms to OIML R76-1:2017 for Class I accuracy, and its internal calibration mechanism aligns with ISO/IEC 17025 clause 6.5.2 on equipment verification. For regulated industries, the device supports GLP and GMP documentation needs via timestamped calibration logs, operator ID prompts (when integrated with external authentication), and non-editable raw data output—facilitating FDA 21 CFR Part 11 readiness when paired with compliant software.
Software & Data Management
Data output follows standard RS-232 ASCII format (e.g., “S+000.1234 g” for stable reading), enabling plug-and-play integration with Microsoft Excel, LabArchives, or custom LIMS platforms. Optional ZiQi Balance Utility software (Windows-based) provides real-time graphing, statistical analysis (mean, SD, CV%), and automated report generation—including calibration history, daily verification records, and trend analysis for preventive maintenance planning. All communication events are logged with UTC timestamps and source identifiers, supporting traceability requirements per ISO 9001 and ISO/IEC 17025.
Applications
- Pharmaceutical QC: Active pharmaceutical ingredient (API) assay, excipient blending verification, and USP repeatability testing.
- Materials science: Precise powder dosing for catalyst synthesis, ceramic slurry formulation, and nanomaterial dispersion quantification.
- Environmental testing: Gravimetric analysis of PM₂.₅ filters, TSP collection media, and solvent residue recovery studies.
- Academic research: Stoichiometric reagent preparation, molar mass determination, and calibration of volumetric glassware per ASTM E542.
- Food & beverage: Nutrient fortification validation, moisture content by loss-on-drying (LOD), and allergen threshold verification.
FAQ
Does the FA2204T meet ISO/IEC 17025 requirements for accredited testing laboratories?
Yes—the balance’s Class I accuracy, documented internal calibration traceability, and built-in performance verification tools support compliance with ISO/IEC 17025:2017 clauses 6.4.3 and 6.5.2.
Can the touchscreen interface be locked to prevent accidental parameter changes during routine weighing?
Yes—user-defined password protection is available for configuration menus, while basic weighing functions remain accessible without authentication.
Is external calibration with certified weights still required if internal calibration is performed regularly?
Internal calibration verifies sensor response but does not replace periodic external verification using NIST-traceable weights per ISO 17025 clause 6.5.3; annual third-party verification is recommended.
What environmental conditions are recommended for optimal performance?
Operate within 15–30°C ambient temperature, ≤70% RH non-condensing, and on a vibration-isolated bench away from HVAC vents or foot traffic.
Does the RS-232 interface support bi-directional communication for remote command execution?
Yes—standard commands (e.g., “SI” for stable weight readout, “CAL” for manual internal calibration trigger) are supported per ZiQi Communication Protocol v2.1.
