OHAUS Defender 3000 i-D33XW Waterproof Floor Scale

Overview

The OHAUS Defender 3000 i-D33XW is a heavy-duty, fully stainless-steel waterproof floor scale engineered for reliability and repeatability in demanding industrial environments. Designed according to the principles of precision load cell transduction and robust mechanical stability, it delivers consistent performance under conditions involving moisture, frequent washdowns, dust ingress, and routine chemical cleaning—common challenges in food processing, pharmaceutical manufacturing, logistics, and chemical handling facilities. Its core architecture integrates an IP67-rated 304 stainless-steel load cell with a fully welded, corrosion-resistant scale deck and support frame. The indicator unit—housed in 304 stainless steel and rated IP66—features a large-format, high-contrast multicolor LCD display optimized for rapid visual interpretation of weight data and pass/fail status in real time.

Key Features

• Fully integrated 304 stainless-steel construction across all structural and functional components—including indicator housing, pan, base frame, and load cell—ensuring long-term resistance to corrosion, pitting, and degradation from caustic cleaners or saline exposure.
• Tri-color backlight LCD display (45 mm digit height) enables immediate visual feedback during checkweighing: green indicates within tolerance, yellow signals near-limit deviation, and red denotes out-of-spec condition—reducing operator dependency on manual interpretation and minimizing inspection errors.
• Four primary operational modes—standard weighing, parts counting, checkweighing, and accumulation—are accessible via intuitive tactile membrane keys, eliminating the need for complex menu navigation in production-line settings.
• Dual power architecture supports uninterrupted operation: built-in rechargeable sealed lead-acid battery (with runtime monitoring) and universal-input AC adapter (110–240 VAC, 50/60 Hz), enabling deployment in locations with unstable or mobile power infrastructure.
• Flexible mounting options include wall bracket, pedestal stand, or direct floor installation; reinforced U-shaped stainless-steel indicator bracket allows adjustable viewing angle and secure positioning in confined or high-traffic zones.

Sample Compatibility & Compliance

The i-D33XW is validated for use with solid, packaged, and bulk materials across a broad range of densities and surface characteristics—provided loads remain within its 150 kg capacity and center-of-gravity constraints. It complies with international metrological standards including OIML R76 for non-automatic weighing instruments and carries NTEP Class III certification for legal-for-trade applications in the United States. Its enclosure ratings (IP66 for indicator, IP67 for load cell) meet IEC 60529 requirements for protection against powerful water jets and temporary submersion. The design adheres to hygiene-critical facility guidelines aligned with FDA 21 CFR Part 11 (when used with compliant data capture systems), EU GMP Annex 11, and ISO/IEC 17025 traceability frameworks for calibration documentation.

Software & Data Management

Data output is natively supported via RS232 serial interface (ASCII protocol, configurable baud rate), enabling seamless integration with label printers, PLCs, SCADA systems, and legacy MES platforms. Optional USB and Ethernet interfaces facilitate modern connectivity: USB supports HID-compliant plug-and-play operation with Windows/Linux workstations, while Ethernet enables TCP/IP-based communication for centralized data logging, remote diagnostics, and integration into Industry 4.0 architectures. All interfaces support timestamped weight records, mode identification, and status flags—critical for audit-ready documentation in regulated environments. Firmware updates are performed via USB drive, ensuring version control and traceability per internal quality management system requirements.

Applications

• Food & Beverage: In-line checkweighing of filled packages (bags, trays, crates), raw material batching, and yield tracking in wet-processing lines.
• Pharmaceuticals: Weighing of active pharmaceutical ingredients (APIs), excipients, and intermediate blends under cGMP-compliant conditions where surface sanitation and material compatibility are mandatory.
• Chemical Manufacturing: Handling of corrosive or hygroscopic compounds requiring frequent decontamination cycles without instrument downtime.
• Logistics & Warehousing: Pallet-level verification, parcel sorting, and inventory reconciliation in humid or outdoor staging areas.
• Recycling & Waste Management: Gross/net tare operations for mixed-material containers exposed to rain, condensation, or process fluids.

FAQ

What environmental conditions is the i-D33XW rated for?
It is certified IP66 for the indicator and IP67 for the load cell, meaning it withstands high-pressure water jets and temporary immersion up to 1 meter for 30 minutes.
Is this scale approved for trade use in North America?
Yes—the model i-D33XW150C1X5ZH holds NTEP Class III approval for commercial weighing applications in the U.S. and Canada.
Can the tri-color checkweighing display be customized for specific tolerance bands?
Yes—upper and lower limits, along with associated color assignments, are programmable via the front-panel interface or remote configuration tools.
Does the scale support GLP/GMP-compliant data recording?
When connected to validated external software (e.g., OHAUS Logger Pro or third-party LIMS), it provides full audit trail capability, user authentication, and electronic signature support per 21 CFR Part 11 requirements.
What maintenance intervals are recommended for long-term accuracy?
Annual calibration verification against traceable standards is advised; daily zero checks and periodic load-cell diagnostics are supported through onboard self-test functions.
