OHAUS Defender 3000 i-D33XW Waterproof Platform Scale

Overview

The OHAUS Defender 3000 i-D33XW is an industrial-grade waterproof platform scale engineered for reliable performance in demanding production, packaging, logistics, and food processing environments where moisture, particulate ingress, and frequent cleaning are routine operational conditions. Built upon OHAUS’s legacy of robust weighing instrumentation, this scale employs a full 304 stainless steel mechanical architecture—including load cell housing, platform, support frame, and indicator enclosure—to ensure structural integrity and long-term corrosion resistance. Its measurement principle relies on high-stability electromagnetic force compensation (EMFC) technology integrated with a hermetically sealed IP67-rated load cell, delivering consistent repeatability and minimal drift under thermal or mechanical stress. The indicator features an IP66-rated enclosure, enabling operation in high-humidity zones, splash-prone workstations, or areas subject to periodic low-pressure washdown procedures—making it suitable for facilities adhering to USDA, FDA, and EU hygiene directives.

Key Features

• Full 304 stainless steel construction across all major components: indicator housing, weighing platform, support structure, and internal sensor assembly.
• Tri-color backlit LCD display (45 mm digit height) with intuitive visual feedback during checkweighing—green for in-tolerance, yellow for near-limit, red for out-of-spec—reducing operator error and accelerating throughput.
• Dual-power architecture: integrated rechargeable lead-acid battery (up to 120 hours standby) and universal AC input (110–240 VAC, 50/60 Hz), ensuring uninterrupted operation during power fluctuations or mobile deployment.
• Flexible mounting system with adjustable stainless steel U-bracket, compatible with recessed floor installations, benchtop integration, or wall-mounted configurations.
• Four core operating modes—Weighing, Counting, Checkweighing, and Accumulation—configured via tactile membrane keys optimized for gloved-hand use in industrial settings.
• Standard RS232 serial interface for direct connection to label printers, PLCs, or legacy MES systems; optional USB or Ethernet modules enable seamless integration into modern IIoT architectures and centralized data logging platforms.

Sample Compatibility & Compliance

The i-D33XW is designed for non-hazardous solid and semi-solid materials commonly handled in manufacturing and distribution workflows—including packaged goods, raw ingredients, assembled components, and returnable containers. Its sealed mechanical design meets the environmental protection requirements of IP66 (indicator) and IP67 (load cell), aligning with IEC 60529 standards for dust-tightness and temporary water immersion resistance. While not certified for explosive atmospheres (ATEX/IECEx), its material selection and ingress protection make it appropriate for Class I, Division 2 or Zone 2 environments when used outside ignition-source zones. The scale supports Good Manufacturing Practice (GMP) documentation workflows through audit-ready configuration logs and user-accessible calibration history—compatible with 21 CFR Part 11-compliant software when paired with OHAUS Logger Pro or third-party SCADA systems.

Software & Data Management

The indicator operates independently without external software but supports bidirectional ASCII protocol communication via RS232, enabling real-time weight streaming, command-driven tare/reset functions, and batch ID tagging. When connected to OHAUS Logger Pro (Windows-based), users can configure automated data capture intervals, apply statistical process control (SPC) filters, generate PDF reports compliant with ISO 9001 documentation requirements, and export CSV or Excel-formatted datasets for traceability audits. Optional Ethernet connectivity allows integration with SQL databases or cloud-based quality management systems (QMS), supporting electronic record retention per FDA 21 CFR Part 11 when deployed with validated user authentication and change-control protocols.

Applications

• Food & beverage production lines: ingredient batching, portion control verification, and final-pack checkweighing prior to case packing.
• Pharmaceutical secondary packaging: tablet/capsule counting, vial fill verification, and carton accumulation before palletization.
• Automotive and electronics assembly: component kitting validation, sub-assembly weight reconciliation, and WIP inventory reconciliation.
• Distribution centers: parcel manifest verification, pallet load optimization, and return-goods inspection workflows.
• Chemical and agrochemical handling: drum filling confirmation, bagged product reconciliation, and hazardous-material transfer documentation (when used outside classified zones).

FAQ

Is the i-D33XW suitable for continuous outdoor use?
No—it is rated for indoor industrial environments with occasional moisture exposure. Prolonged UV exposure, freezing temperatures, or sustained rain contact may compromise seal integrity and battery performance.
Can the scale be calibrated internally without external weights?
Yes—internal calibration is supported via menu-driven procedure using factory-programmed reference values; however, external calibration with NIST-traceable weights is required for ISO/IEC 17025 accreditation or regulatory audits.
Does the tri-color checkweighing function support custom tolerance bands?
Yes—users can define upper/lower limits and intermediate thresholds via the setup menu, assigning distinct backlight colors to each zone for multi-tier pass/fail evaluation.
What is the expected service life of the included lead-acid battery?
Under typical usage (8 hrs/day, 5 days/week), the battery maintains ≥80% capacity for approximately 2–3 years; replacement kits (OHAUS part # BATT-PLAT-3000) are field-serviceable without disassembly.
Is firmware update capability available?
Yes—firmware upgrades are performed via RS232 using OHAUS-provided utility software; version history and release notes are published on the official OHAUS support portal for registered customers.
