Precisa XS6250D-SCS Economic Internal Calibration Electronic Balance

Overview

The Precisa XS6250D-SCS is an economical, entry-level internal calibration electronic balance engineered for routine mass measurement tasks in quality control laboratories, educational institutions, and light industrial environments. It operates on electromagnetic force compensation (EMFC) principle—where the restoring force required to maintain the load cell in equilibrium is precisely measured and converted into a digital mass reading. This architecture ensures high reproducibility and long-term stability without mechanical wear. Designed for daily use under non-GxP-critical conditions, the XS6250D-SCS delivers consistent 0.1 g readability across its full 6250 g capacity, with linearity error maintained within ±0.15 g and repeatability ≤0.1 g—meeting ISO 9001-aligned metrological requirements for general-purpose weighing.

Key Features

• Integrated internal calibration mechanism eliminates dependency on external reference weights, reducing operational overhead and minimizing traceability gaps during routine verification.
• Fluorescent display option ensures high-contrast, wide-angle readability under variable ambient lighting—including low-light or glare-prone workspaces—without requiring backlight adjustment or user proximity.
• Three-step adjustable stability setting allows users to optimize response time versus noise rejection based on environmental vibration levels or sample volatility (e.g., powders, hygroscopic materials).
• Auto-power-on functionality resumes operation after power interruption, preserving last-used configuration and eliminating manual reset delays.
• Programmable auto-off timer conserves energy and extends component service life while complying with IEC 62368-1 safety standards for low-power instrumentation.
• Robust chrome-nickel steel weighing pan (200 × 200 mm) resists corrosion and mechanical abrasion, supporting frequent cleaning and compatibility with common laboratory solvents.

Sample Compatibility & Compliance

The XS6250D-SCS accommodates a broad range of solid and granular samples up to 6.25 kg, including bulk reagents, packaged goods, ceramic components, and educational specimens. Its tare range matches full capacity (6250 g), enabling direct subtraction of container mass without range limitation. While not certified for GLP/GMP-regulated batch release or USP critical weighing applications, the balance conforms to OIML R76-1 (2017) Class III accuracy requirements for non-automatic weighing instruments. It supports basic traceability via internal calibration log (non-auditable), and its temperature drift specification (±4 ppm/°C between 10–30 °C) aligns with EN 45501:2015 environmental performance criteria for laboratory balances used outside climate-controlled rooms.

Software & Data Management

The XS6250D-SCS features standard RS-232 interface for bidirectional communication with PCs or LIMS systems. It transmits stable weight values, tare status, unit selection, and calibration timestamps in ASCII format—enabling integration with third-party data acquisition software (e.g., LabX Lite, Excel-based macros). No proprietary driver or cloud platform is required. Though it does not support FDA 21 CFR Part 11-compliant electronic signatures or audit trails, its firmware retains calibration history (date/time stamp only) for internal QA review. Data export is compatible with ISO/IEC 17025 documentation workflows when paired with validated serial capture protocols.

Applications

• Raw material receipt inspection in food, pharmaceutical, and chemical distribution centers.
• Formulation batching for non-critical excipients or diluents in pilot-scale R&D labs.
• Student experiments in physics and chemistry curricula requiring reliable mass determination at sub-gram resolution.
• Inventory management and packaging line checkweighing where ±0.15 g linearity meets process tolerance bands.
• Field-deployed calibration verification of lower-precision instruments using internal reference.

FAQ

Does the XS6250D-SCS support external calibration with certified weights?
Yes—the balance accepts manual calibration via external weights through its dedicated calibration mode, though internal calibration is recommended for routine daily verification.
Is the fluorescent display standard or optional?
The fluorescent display is an optional configuration; units may also be supplied with standard LCD depending on regional ordering specifications.
What is the warranty coverage and service support structure?
Precisa provides a 24-month limited manufacturer warranty covering parts and labor for defects in materials or workmanship, serviced through authorized Precisa distributors in EMEA, APAC, and Americas regions.
Can this balance operate continuously in uncontrolled warehouse environments?
It is rated for 0–40 °C ambient operation, but sustained use above 30 °C may affect sensitivity drift performance; humidity should remain below 80 % RH non-condensing to prevent condensation on internal electronics.
Is the RS-232 interface galvanically isolated?
No—RS-232 communication uses standard single-ended signaling; for electrically noisy industrial settings, use of an opto-isolated USB-to-RS232 adapter is advised to prevent ground-loop interference.
