Precisa XS8250D Precision Laboratory Balance

Overview

The Precisa XS8250D is a high-stability, general-purpose laboratory balance engineered for routine mass measurement tasks in quality control laboratories, educational institutions, and industrial preparation areas. Utilizing electromagnetic force compensation (EMFC) technology, the XS8250D delivers consistent, drift-resistant performance across its full 8,250 g capacity with 0.1 g readability. Its robust mechanical architecture—featuring a chromium-nickel steel weighing pan and precision-machined load cell housing—ensures long-term repeatability and resistance to mechanical shock and thermal gradients. Designed for continuous operation under variable ambient conditions (0–40 °C), the balance incorporates real-time environmental compensation algorithms that mitigate sensitivity drift (±4 ppm/°C between 10–30 °C), making it suitable for non-climate-controlled lab environments where temperature fluctuation is common.

Key Features

• Fluorescent display option ensures legible readouts under low-light, high-ambient-light, or oblique viewing conditions—critical for multi-user labs and production floor integration.
• User-defined internal calibration with customizable weight values eliminates dependency on certified external masses; supports traceable calibration workflows without third-party verification costs.
• Three-step stability adjustment allows operators to optimize response speed versus noise rejection based on sample volatility (e.g., powders vs. dense solids) and bench vibration levels.
• Auto-power-on functionality resumes operation after power interruption, preserving last-used settings and reducing manual reconfiguration time.
• Programmable auto-off delay (configurable via front-panel menu) conserves energy and extends component service life without compromising workflow continuity.
• Compliant with EN 45501 (formerly OIML R76) for non-automatic weighing instruments, supporting metrological traceability in regulated environments.

Sample Compatibility & Compliance

The XS8250D accommodates samples up to 8.25 kg with a 200 × 200 mm stainless steel pan, optimized for bulk solids, packaged goods, and medium-volume containers. Its wide tare range (–8250 g to +8250 g) enables precise net-weight determination of large vessels or nested packaging configurations. The balance meets ISO/IEC 17025 requirements for equipment suitability when used within defined environmental and operational parameters. While not intrinsically rated for hazardous locations, its design conforms to IEC 61010-1 safety standards for electrical laboratory equipment. It supports GLP documentation practices through stable output formatting and timestamp-ready RS232 interface (optional USB or Ethernet modules available).

Software & Data Management

Data output is supported via standard RS232 serial interface (9600 baud, ASCII protocol), enabling seamless integration with LIMS, ERP, or custom QA databases. Optional connectivity modules allow direct export to Excel-compatible CSV files or real-time streaming into statistical process control (SPC) platforms. All calibration events—including date, operator ID (if configured), and deviation logs—are retained in non-volatile memory for audit readiness. Firmware supports user-accessible calibration history and sensor diagnostic reports, aligning with FDA 21 CFR Part 11 principles for electronic record integrity when paired with validated host software.

Applications

• Raw material receipt inspection in pharmaceutical and food manufacturing facilities.
• Batch formulation and ingredient dispensing in chemical synthesis labs.
• Education: Student experiments requiring reliable mass measurement at sub-gram resolution.
• Environmental testing labs performing soil/sediment sample weighing prior to extraction.
• Logistics centers verifying shipment weights against manifest data.
• Calibration laboratories performing intermediate checks on higher-capacity balances using calibrated reference loads.

FAQ

Is the XS8250D compliant with ISO/IEC 17025 for accredited testing laboratories?
Yes—when operated within specified environmental limits and maintained per Precisa’s recommended calibration schedule, the XS8250D satisfies Clause 6.4.10 (Equipment Verification) and supports documented uncertainty estimation per ISO/IEC 17025:2017 Annex A.
Can the fluorescent display be retrofitted on existing units?
No—the fluorescent display is a factory-configured option; it cannot be added post-purchase due to integrated driver circuitry and housing modifications.
What is the recommended recalibration interval under GLP conditions?
Precisa recommends daily zero-checks, weekly span verification using a certified 5 kg test weight, and full two-point calibration every 3 months—or immediately after relocation, mechanical impact, or ambient temperature shifts exceeding 5 °C.
Does the balance support dynamic weighing (e.g., animal or liquid filling applications)?
No—the XS8250D is designed for static weighing only; it lacks dynamic filtering algorithms or stabilization modes required for moving or unstable loads.
Is firmware upgrade capability available?
Yes—firmware updates are distributed via Precisa’s authorized service network and require connection to a certified service terminal; end users cannot perform upgrades independently.
