Overview
The Precisa XS8250D-SCS is a robust, entry-level internal calibration electronic balance engineered for routine mass measurement tasks in quality control laboratories, educational institutions, and light industrial environments. Designed according to fundamental principles of electromagnetic force compensation (EMFC), it delivers stable and repeatable measurements across its full 8.25 kg capacity with 0.1 g resolution. Its internal calibration mechanism—activated via front-panel command—eliminates dependency on external reference weights during daily verification, reducing operational overhead while maintaining traceability to national standards through factory-certified internal calibration masses. The balance operates within an ambient temperature range of 0–40 °C and features thermal compensation algorithms that limit sensitivity drift to ±4 ppm/°C between 10–30 °C—ensuring consistent performance under typical laboratory conditions.
Key Features
- Internal calibration system with one-touch activation, compliant with ISO 9001 and GLP documentation requirements when paired with audit-trail-enabled software.
- Fluorescent display (optional configuration) offering high contrast and wide viewing angle—optimized for readability under low-light or oblique observation conditions without backlight dependency.
- Three-step stability adjustment allows users to fine-tune response dynamics for varying sample types: fast mode for gross weighing, standard for general use, and slow mode for vibration-prone or draft-sensitive environments.
- Automatic power-on at mains restoration and programmable auto-off (user-selectable idle timeout) support energy efficiency and device longevity.
- Chrome-nickel steel weighing pan (200 × 200 mm) provides corrosion resistance and mechanical durability for repeated handling of bulk solids, containers, or packaged goods.
- Compact footprint (210 × 340 × 89 mm) and lightweight design (5.6 kg net) facilitate integration into space-constrained workbenches or mobile lab carts.
Sample Compatibility & Compliance
The XS8250D-SCS accommodates a broad range of sample formats—including powders, granules, liquids in tared vessels, and pre-packaged items—within its 8250 g tare capacity. Its overload protection safeguards the load cell against accidental overloading up to 150% of nominal capacity. The balance meets essential regulatory prerequisites for non-automatic weighing instruments under OIML R76-1 (2021) and EU Directive 2014/31/EU. While not certified for legal-for-trade applications out-of-the-box, its linearity (±0.15 g), reproducibility (≤0.1 g), and thermal stability align with ASTM E898–22 guidelines for laboratory-grade balances used in non-regulated QC workflows. Full compliance documentation—including factory calibration certificate and conformity statement—is supplied with each unit.
Software & Data Management
The XS8250D-SCS supports RS232 serial output for direct connection to PCs, LIMS, or statistical process control (SPC) platforms. When interfaced with Precisa’s optional BalanceLink™ software (v3.2+), users gain access to configurable data logging, timestamped calibration event records, user-defined report templates, and export to CSV/Excel formats. The software enforces 21 CFR Part 11–compatible audit trails for calibration actions, operator identification, and parameter changes—meeting basic GxP data integrity expectations for regulated environments where formal validation is not mandated. No proprietary drivers are required; standard Windows COM port configuration suffices.
Applications
This balance serves as a cost-effective solution for standardized procedures requiring moderate precision but high operational uptime: raw material receipt inspection in food or chemical manufacturing; formulation batch checks in pharmaceutical pilot plants; student experiments in analytical chemistry labs; packaging weight verification in distribution centers; and inventory reconciliation in warehouse management systems. Its rapid stabilization (<2 s) and wide dynamic range make it suitable for both single-item weighing and cumulative dosing operations—particularly where frequent taring is required across heterogeneous container types.
FAQ
Does the XS8250D-SCS require external calibration weights?
No—it incorporates a motorized internal calibration mass and performs full-range verification autonomously upon user command or scheduled intervals.
Is the fluorescent display standard or optional?
Fluorescent display is an optional configuration; units may be ordered with standard LCD depending on regional specification and order code.
Can this balance be validated for GMP environments?
While the hardware meets foundational metrological criteria, formal GMP validation requires documented IQ/OQ/PQ protocols, environmental monitoring, and integration with qualified software—services available through Precisa’s Application Support team.
What is the warranty coverage period?
The instrument carries a 24-month limited manufacturer warranty covering parts and labor, commencing from date of shipment.
Is the balance compatible with 230 V / 50 Hz supply in Europe?
Yes—the dual-voltage input (115/230 V AC, 50–60 Hz) and ±20% voltage tolerance ensure reliable operation across European, North American, and Asian utility grids.
