Overview
The SHYP JA5003B Precision Electronic Balance is a high-reliability analytical-grade instrument engineered for routine mass measurement in quality control laboratories, academic research settings, and pharmaceutical production environments. Built upon electromagnetic force compensation (EMFC) sensor technology, it delivers rapid stabilization (<3 seconds), exceptional repeatability (±0.001 g), and long-term drift stability under ambient laboratory conditions. Unlike strain-gauge-based platforms, the EMFC architecture ensures linearity across the full 0–500 g range without mechanical hysteresis, making it suitable for applications requiring traceable mass determination per ISO/IEC 17025 and USP . The balance operates within standard environmental tolerances (10–30 °C, ≤80% RH non-condensing) and is designed for continuous duty in ISO Class 7 cleanrooms or controlled lab spaces.
Key Features
- Electromagnetic force compensation (EMFC) transducer with auto-zero tracking and dynamic damping control
- Five-sided transparent acrylic draft shield—removable and statically dissipative—to minimize air current interference while enabling unobstructed sample observation
- Backlit LCD display (128 × 64 pixels) with adjustable contrast and dual-line readout (mass + status indicator)
- Internal overload protection (up to 150% of max capacity) and real-time fault diagnostics with error code logging
- Four-point linear calibration routine supported by external weights (class E2 or better recommended)
- Integrated below-balance weighing hook for density determination and suspended measurements
- RS232C serial interface compliant with standard ASCII protocol; supports bi-directional communication with LIMS, ERP, or custom data acquisition software
Sample Compatibility & Compliance
The JA5003B accommodates samples up to 500 g on its 80 mm diameter stainless-steel weighing pan. Its open-frame design and low-profile pan geometry support volumetric vessels (e.g., beakers, crucibles, density bottles) and irregular solids—including powders, granules, and small components—without compromising stability. The unit meets CE conformity requirements under the EU Measuring Instruments Directive (MID 2014/32/EU) for non-automatic weighing instruments (NAWI). While not certified to OIML R76 or NIST Handbook 44 out-of-the-box, it is fully configurable for GLP/GMP workflows: audit trail functionality (via connected PC), user access levels, and electronic signature support can be implemented through compatible third-party software aligned with FDA 21 CFR Part 11 Annex 11 requirements.
Software & Data Management
Data output follows standard ASCII format via RS232C at 9600 baud, 8N1 configuration—compatible with Microsoft Excel, LabArchives, and OpenLab CDS without proprietary drivers. Optional SHYP DataLink software (v3.2+) enables automated timestamped export, batch ID tagging, statistical summary (mean, SD, CV%), and PDF report generation. All measurement events—including calibration records, zero adjustments, and overload alerts—are timestamped and stored in non-volatile memory. For regulated environments, integration with validated electronic lab notebooks (ELNs) allows full traceability from raw mass reading to final QC release decision.
Applications
- Quantitative formulation in pharmaceutical tablet manufacturing (e.g., active ingredient dispensing, excipient blending verification)
- Gravimetric analysis in chemistry labs (precipitate drying, ash content determination, moisture loss on drying)
- Calibration transfer of reference standards in metrology labs (supporting ISO 17025 clause 6.5)
- Material density and specific gravity testing using Archimedes’ principle with optional sinker kit
- Counting operations for uniform parts (e.g., screws, tablets, microcomponents) with built-in piece-count mode
- Education and training in analytical chemistry curricula where reproducibility and uncertainty awareness are emphasized
FAQ
What calibration weights are required for routine verification?
Class E2 stainless-steel weights (500 g, 200 g, 100 g, and 10 g) are recommended for full-range linearity verification per ISO 9001 Clause 7.6.
Is internal calibration available on the JA5003B?
No—this model uses external calibration only. Internal motorized calibration is not implemented; users must perform manual two-point (zero and span) calibration using certified masses.
Can the balance operate on battery power?
No—the JA5003B requires continuous AC power (100–240 V, 50/60 Hz) via included switching adapter; no onboard battery option is provided.
Does the RS232 interface support print-to-USB printers?
Not natively—direct USB printing requires an RS232-to-USB converter and appropriate driver installation; native USB host capability is absent.
What maintenance intervals are recommended for optimal performance?
Daily cleaning of pan and draft shield with lint-free cloth and isopropyl alcohol; quarterly verification of leveling feet and shock absorber integrity; annual sensor diagnostic check by authorized SHYP service partner.
