Overview
The ZiQi FA2004T is a high-precision analytical balance engineered for laboratories requiring consistent mass measurement at the 0.1 mg readability level (1 × 10⁻⁴ g). Built upon electromagnetic force compensation (EMFC) sensor technology, it delivers rapid stabilization—typically within ≤4 seconds—and maintains metrological integrity across its full 200 g capacity range. Designed and manufactured in Shanghai by ZiQi, a vertically integrated instrument producer, the FA2004T complies with OIML R76-1 Class I accuracy requirements for analytical balances and meets fundamental performance criteria aligned with ISO/IEC 17025 calibration traceability frameworks. Its robust die-cast aluminum housing provides mechanical stability, electromagnetic interference (EMI) shielding, and resistance to environmental perturbations common in shared lab environments.
Key Features
- Electromagnetic force compensation (EMFC) transducer system ensuring high linearity, low hysteresis, and long-term drift stability
- 5-inch capacitive touchscreen interface with intuitive icon-driven navigation and multilingual UI support (English default)
- Programmable automatic internal calibration—user-configurable intervals (e.g., hourly, daily, or on-demand) with real-time calibration status indicator
- Full-range tare, zero tracking, cumulative weighing, overload/underload detection, and audible/visual fault alerts
- Built-in density determination mode (solid/liquid) and percentage weighing functionality for formulation and quality control workflows
- Integrated RS-232 serial port compliant with EIA/TIA-232-F standards, enabling direct connection to label printers, PCs, or LIMS systems without additional adapters
- Enhanced operational versatility via counting mode (pieces per unit mass), unit conversion (g, mg, oz, ct, etc.), and below-balance weighing with optional hook assembly
Sample Compatibility & Compliance
The FA2004T accommodates standard analytical samples—including powders, granules, small components, and vials—on its Ø80 mm stainless steel weighing pan. Its design supports GLP-compliant operation through audit-trail-capable data logging when paired with compliant software (e.g., ZiQi BalanceLink or third-party SPC tools). While the balance itself does not embed FDA 21 CFR Part 11 electronic signature capabilities, its RS-232 output enables integration into validated systems where data integrity, user access control, and change history are managed at the host application layer. It conforms to IEC 61326-1 (EMC) and IEC 61010-1 (safety) standards for laboratory electrical equipment.
Software & Data Management
Data export is facilitated via ASCII-based RS-232 protocol using standard framing (9600 baud, 8N1). ZiQi provides optional BalanceLink software for Windows OS, supporting real-time data streaming, batch export to CSV/Excel, and customizable print templates for GLP-aligned reports. All transmitted data include timestamp, net weight, tare value, unit identifier, and operator ID (if entered manually). The firmware supports configurable data formatting (e.g., fixed decimal places, trailing zero suppression) to align with internal SOPs. No onboard memory is provided; persistent storage must be handled externally per laboratory data governance policies.
Applications
The FA2004T serves routine and regulated applications across pharmaceutical QC labs (e.g., assay preparation, reference standard weighing per USP ), academic research (gravimetric analysis, catalyst loading), materials science (powder blending verification), and food testing (nutrient fortification dosing). Its repeatability of ±0.0002 g and linearity error of ±0.0003 g ensure suitability for ASTM E899-22 (standard practice for balance verification) and ISO 17034 reference material certification support tasks. The fast stabilization time enhances throughput in high-volume sample preparation workflows without compromising measurement fidelity.
FAQ
What calibration standards are required for initial verification?
A certified Class F1 or E2 weight set (per OIML R111) is recommended for as-received verification and periodic performance checks.
Is external calibration necessary if internal calibration is performed regularly?
Yes—internal calibration verifies sensor response but does not replace external verification using traceable standards to confirm metrological conformity per ISO/IEC 17025 clause 6.5.
Can the balance operate in draft-free enclosures with restricted airflow?
Yes—the EMFC mechanism is insensitive to minor air current fluctuations; however, full enclosure use requires confirmation of thermal equilibrium to avoid convection-induced drift.
Does the RS-232 interface support Modbus RTU or other industrial protocols?
No—it implements a proprietary ASCII command set optimized for lab instrumentation interoperability; custom drivers may be developed using documented protocol specifications.
How is temperature drift compensated during extended operation?
The system incorporates real-time ambient temperature monitoring and applies factory-characterized thermal gain correction algorithms embedded in firmware.
