Overview
The SHYP JA10003 Precision Balance is an electromagnetic force compensation-based analytical instrument engineered for high-reproducibility mass measurement in regulated and non-regulated laboratory settings. Operating on the principle of electromagnetic force restoration, the balance dynamically counterbalances sample weight via a precisely controlled coil system within a permanent magnetic field—ensuring linearity, thermal stability, and minimal drift over extended operation. With a maximum capacity of 1000 g and readability of 1 mg (0.001 g), it meets the performance requirements for routine quality control, formulation verification, sample preparation, and educational applications where ±0.002 g repeatability and <±0.005 g linearity error are acceptable per ISO 17025–aligned internal calibration protocols. Its compact footprint and robust mechanical architecture support integration into fume hoods, clean benches, and QC workstations without compromising structural integrity or metrological performance.
Key Features
- Electromagnetic force compensation sensor with auto-zero tracking and dynamic damping control for rapid stabilization (<3 s typical response time)
- Five-sided transparent draft shield with removable glass panels for unobstructed sample access and visual monitoring during weighing
- Backlit LCD display with 18-mm character height, optimized for low-contrast ambient lighting and operator ergonomics
- Integrated lower-hook assembly enabling below-balance weighing (e.g., density determination, magnetic susceptibility testing)
- External calibration capability using Class M2 or better standard weights; supports four-point linear calibration across 0%, 25%, 50%, and 100% of full scale
- Overload protection circuitry prevents sensor damage up to 150% of rated capacity (1500 g)
- RS232C serial interface compliant with standard ASCII command protocol (e.g., “S” for stable reading, “W” for weight output) for seamless integration with LIMS, ELN, or custom data acquisition software
Sample Compatibility & Compliance
The JA10003 accommodates samples up to 1000 g placed on its Ø80 mm stainless-steel weighing pan. Its open-top draft shield design allows handling of volumetric flasks, crucibles, beakers, and irregularly shaped objects while maintaining environmental isolation from air currents. The balance complies with fundamental metrological requirements outlined in OIML R76-1 (2017) for Class II non-automatic weighing instruments and aligns with ISO 9001:2015 clause 7.1.5.2 for monitoring and measuring resource control. While not certified to FDA 21 CFR Part 11 out-of-the-box, audit trails—including calibration logs, zero checks, and weight records—can be captured externally via RS232C and archived under institutional GLP/GMP documentation systems.
Software & Data Management
No proprietary software is bundled; however, the RS232C port enables direct communication with third-party platforms including LabArchives ELN, Thermo Fisher SampleManager LIMS, and Excel-based macros using standard terminal emulation (e.g., PuTTY, Tera Term). Data output format is configurable (grams only, or with unit suffix), and transmission triggers include manual keypress, timed interval (1–60 s), or stability detection. All firmware-level operations—including calibration date stamping, operator ID entry (via external keyboard), and error code logging—are retained in non-volatile memory and retrievable via serial query commands.
Applications
- Weighing raw materials and intermediates in pharmaceutical manufacturing (per USP and EP 2.1.1 guidelines)
- Preparation of standard solutions and buffer stocks in clinical chemistry and environmental testing labs
- Counting small components (e.g., screws, tablets, microcentrifuge tubes) using built-in piece-counting mode with user-defined reference weight
- Density determination of solids via hydrostatic weighing (using optional sinker kit and immersion accessories)
- Educational use in undergraduate physics and chemistry laboratories for teaching measurement uncertainty, significant figures, and statistical process control
- Inventory reconciliation and packaging line verification in food and cosmetics production facilities
FAQ
Does the JA10003 support internal calibration?
No—it requires external calibration using traceable standard weights. Internal calibration is not implemented in this model.
Is the RS232C interface compatible with modern Windows/macOS systems?
Yes, when used with a USB-to-RS232 adapter and appropriate driver installation; no additional SDK or license is required.
What is the temperature operating range for stable performance?
10–30 °C ambient, with ≤80% RH non-condensing; performance specifications assume thermal equilibrium ≥2 hours after power-on.
Can the balance store multiple calibration records?
No—calibration events are not logged internally, but timestamps and results can be captured externally via serial output during calibration procedures.
Is the draft shield removable for cleaning?
Yes—the five-panel glass shield detaches without tools and may be cleaned with isopropyl alcohol and lint-free cloth per manufacturer recommendations.
