Overview
The 10KBF Precision Electronic Balance is an entry-level yet rigorously engineered analytical weighing instrument designed for routine mass measurement tasks in quality control laboratories, educational institutions, and industrial R&D settings. Built upon a robust metal-sprayed chassis and featuring a corrosion-resistant stainless-steel weighing pan (160 mm × 160 mm), the balance delivers mechanical stability under variable environmental conditions—critical for minimizing drift during extended weighing sessions. Its dual readability mode (0.1 g / 1 g) enables flexible operation across applications requiring either enhanced resolution for small-sample quantification or rapid gross-weight assessment of larger specimens. The device operates on standard AC 220 V / 50 Hz power, eliminating dependency on external battery systems and ensuring uninterrupted workflow continuity in fixed-location installations.
Key Features
- Stainless-steel weighing pan with optimized geometry for uniform load distribution and minimal edge-loading error
- Metal-sprayed base structure providing high rigidity and resistance to mechanical shock and vibration
- Dual-range readability selection (0.1 g and 1 g) via front-panel controls—no software configuration required
- Tare function with auto-zero tracking to maintain baseline integrity during sequential sample measurements
- Counting mode with automatic unit weight calibration and statistical batch count verification
- Configurable display interface: selectable LED (high-brightness, low-power) or LCD (wide viewing angle, ambient-light adaptive)
- Integrated overload protection circuitry safeguarding the load cell against accidental overloading up to 150% of rated capacity
Sample Compatibility & Compliance
The 10KBF accommodates a broad range of sample types—including powders, granules, solid components, and packaged reference standards—within its 10 kg maximum capacity and 160 mm × 160 mm pan footprint. Its design adheres to fundamental metrological principles outlined in OIML R 76-1 (2021) for non-automatic weighing instruments, and supports traceable calibration protocols aligned with ISO/IEC 17025 requirements. While not certified for GLP/GMP-regulated production environments without additional validation documentation, the balance is routinely deployed in pre-production testing, raw material inspection, and academic teaching labs where intermediate accuracy and operational reliability are prioritized over regulatory-grade audit trails. It meets basic electromagnetic compatibility (EMC) criteria per EN 61326-1 for laboratory equipment.
Software & Data Management
The 10KBF features RS-232 serial output as standard, enabling direct connection to PCs, printers, or LIMS endpoints for automated data capture. No proprietary software suite is bundled; instead, it supports ASCII-based communication protocols compatible with common laboratory data acquisition tools (e.g., LabVIEW, MATLAB Serial Interface, or custom Python scripts using pySerial). All transmitted records include timestamp (when enabled externally), net weight, tare value, unit count, and mode identifier—facilitating post-acquisition traceability and spreadsheet integration. Though lacking built-in 21 CFR Part 11-compliant electronic signature or audit trail functionality, the device may be incorporated into validated workflows when paired with compliant host systems that manage user access control and data integrity logging.
Applications
- Raw material receipt inspection in chemical manufacturing and pharmaceutical excipient handling
- Batch formulation support in food processing and nutraceutical labs
- Student experiments in university physics, chemistry, and materials science curricula
- Inventory management and component counting in electronics assembly and mechanical workshops
- Calibration verification of secondary standards using certified reference weights (Class M2 or better)
- Environmental sample preparation in municipal water testing facilities (e.g., filter drying and residue mass determination)
FAQ
What is the minimum detectable mass increment on the 10KBF Balance?
The device offers two selectable readability settings: 0.1 g for high-resolution tasks and 1 g for rapid gross weighing—both calibrated and verified at factory level.
Does the 10KBF support internal calibration?
No. Internal calibration is not implemented; external calibration using traceable weights is required prior to use and at defined intervals per lab SOPs.
Can this balance be used in a fume hood or high-humidity environment?
It is not IP-rated for dust or moisture ingress. Operation in controlled indoor environments (15–30 °C, ≤70% RH, non-condensing) is recommended to ensure long-term repeatability.
Is the RS-232 interface opto-isolated?
No. The interface is electrically referenced to the balance’s internal ground; use of an isolated USB-to-RS232 adapter is advised when interfacing with sensitive host systems.
What maintenance is required to sustain performance?
Monthly cleaning of the pan and housing with lint-free cloth and isopropyl alcohol; annual verification by accredited service provider recommended for critical applications.
