OHAUS Valor 2000 Waterproof Bench Scale

Overview

The OHAUS Valor 2000 Waterproof Bench Scale is an industrial-grade weighing instrument engineered for rigorous use in wet, washdown, and high-hygiene production environments—particularly food processing, meat packing, seafood handling, and ready-to-eat meal facilities. Built on OHAUS’s legacy of precision metrology and robust mechanical design, the Valor 2000 implements a load cell-based force measurement architecture optimized for dynamic stability under mechanical vibration and thermal drift. Its core functionality centers on rapid, repeatable mass determination under variable ambient conditions—including condensation, splashing, and periodic high-pressure water cleaning. Unlike standard bench scales, the Valor 2000 integrates structural waterproofing at the system level—not merely as a sealed enclosure, but as a holistic design encompassing gasketed interfaces, conformal-coated electronics, sloped drainage surfaces, and corrosion-resistant fasteners. This enables continuous operation in environments where ISO 22000, HACCP, and FDA 21 CFR Part 110 compliance are mandatory.

Key Features

• IPX8-rated enclosure: Fully submersible up to 1 meter for 30 minutes; validated for repeated exposure to chlorinated or caustic cleaning agents used in food plant sanitation protocols.
• Dual-facing red LED display: 0.8-inch (20.5 mm) high digits visible from front and rear positions—critical for line-side verification without operator repositioning or screen rotation.
• Vibration-dampened weighing platform: Engineered mechanical isolation combined with digital filtering algorithms ensures stable readings within ≤0.5 seconds—even on concrete floors adjacent to mixers, conveyors, or hydraulic presses.
• Rechargeable lead-acid battery system: Delivers up to 50 hours of continuous operation on a single charge; supports hot-swap operation via included AC adapter without interrupting weighing sessions.
• Hygienic industrial ergonomics: Seamless ABS housing with no recessed seams or crevices; integrated carry handle; self-closing power port cover; adjustable leveling feet with precision bubble level indicator.
• Tactile membrane keypad: Patented key actuation mechanism resists accidental activation while maintaining positive feedback—designed to withstand repeated contact with gloved hands and resist penetration by sharp tools or bone fragments.

Sample Compatibility & Compliance

The Valor 2000 is validated for direct-contact weighing of raw and processed foodstuffs—including viscous sauces, chilled proteins, frozen dough, and bulk dry ingredients. Its ABS weighing pan and housing meet NSF/ANSI Standard 2 for food equipment and are compatible with common food-grade sanitizers (e.g., 200 ppm chlorine, 1–2% peracetic acid). The scale complies with NTEP Class III accuracy requirements for commercial weighing and supports traceable calibration per ISO/IEC 17025–accredited procedures. It is routinely deployed in facilities undergoing third-party audits for BRCGS Food Safety, SQF Level 3, and IFS Food certification. While not inherently 21 CFR Part 11 compliant out-of-box, its firmware architecture supports audit trail logging and user access control when integrated into validated LIMS or MES platforms.

Software & Data Management

The Valor 2000 operates as a standalone instrument with no embedded operating system or network stack. All configuration—including unit selection (g, kg, lb, oz), auto-zero tracking, auto-off delay, and calibration parameters—is managed via physical keypad navigation. Data output is available through RS-232 serial interface (standard) or optional USB-to-serial adapter, enabling seamless integration with label printers, PLCs, or ERP systems such as SAP EWM or Oracle Manufacturing Cloud. ASCII-formatted weight streams include timestamp (when externally synchronized), gross/net/tare flags, and stability indicators—facilitating automated batch reconciliation and real-time SPC charting in statistical process control software.

Applications

• Portion control and yield monitoring in USDA-inspected meat and poultry processing lines.
• In-line checkweighing of prepackaged salads, deli trays, and frozen entrées prior to metal detection and case packing.
• Ingredient batching in sauce kettles and marinade vats where frequent rinse-down cycles necessitate full waterproof integrity.
• Quality assurance stations in dairy plants performing daily weigh checks on cheese wheels, yogurt tubs, and whey powder lots.
• Sanitation verification workflows—tracking detergent and sanitizer solution volumes dispensed per shift using calibrated volumetric conversion factors.

FAQ

Is the Valor 2000 certified for legal-for-trade use in the United States?

Yes—the model is NTEP-approved for Class III commercial applications and bears Certificate of Conformance #19-042A for capacities ranging from 3 kg to 30 kg (varies by specific variant).
Can the scale be recalibrated onsite without external service?

Yes—both internal and external calibration routines are accessible via the keypad menu; users require only a certified test weight traceable to NIST.
Does the IPX8 rating apply to powered or unpowered operation?

The IPX8 certification covers operation under power, including during active weighing and display illumination—verified under ASTM D3359 cross-hatch adhesion testing and IEC 60529 immersion validation.
What maintenance intervals are recommended for sustained IPX8 performance?

OHAUS recommends quarterly inspection of seal integrity, annual replacement of the battery module, and biannual verification of zero stability after thermal cycling between 5 °C and 40 °C.
Is firmware update capability available?

Firmware updates are performed exclusively via OHAUS-authorized service centers using proprietary diagnostic hardware; no field-upgradable bootloader is provided for cybersecurity and regulatory validation reasons.
