Overview
The OHAUS Defender 3000 i-D33P300B1V3ZH is an industrial floor scale engineered for precision, durability, and operational flexibility in demanding dry-environment production and logistics settings. Built upon OHAUS’ proven Defender platform, this scale employs electromagnetic force compensation (EMFC) transduction technology—optimized for high repeatability and long-term stability under continuous use. Its structural architecture integrates a rigid square-tube carbon steel base with powder-coated finish, supporting a 304 stainless steel weighing pan and an IP65-rated aluminum load cell assembly. Designed to meet the functional requirements of manufacturing line verification, warehouse inventory control, packaging quality assurance, and outbound shipment validation, the i-D33P300B1V3ZH delivers reliable mass measurement across basic weighing, parts counting, checkweighing, and cumulative totalization tasks—without requiring environmental enclosures or climate-controlled infrastructure.
Key Features
- 6-digit, 7-segment multicolor backlit LCD display with 45 mm character height—engineered for legibility under ambient lighting conditions typical of factory floors, including high-glare or low-contrast environments.
- Three-color visual checkweighing feedback (red/yellow/green) directly mapped to user-defined tolerance bands—enabling immediate go/no-go assessment without operator interpretation delay.
- Robust mechanical construction: 304 stainless steel pan; powder-coated square-tube carbon steel frame; IP65-rated aluminum load cell; ABS engineering-grade polymer housing with integrated metal U-bracket for wall, pedestal, or bench mounting.
- Tactile membrane keypad interface with optimized actuation force and tactile feedback—designed for gloved-hand operation and resistance to dust ingress and mechanical wear.
- Dual-power architecture: Standard AC adapter (110–240 VAC, 50/60 Hz) and built-in rechargeable sealed lead-acid battery—supporting uninterrupted operation during power fluctuations or mobile deployment scenarios.
Sample Compatibility & Compliance
The i-D33P300B1V3ZH is rated for dry-industrial environments per IEC 60529 (IP65 ingress protection for the load cell and internal electronics). It complies with OIML R76-1 (2006) and NTEP Class III accuracy requirements for non-automatic weighing instruments used in commercial applications. While not certified for hazardous locations or wet-process areas, its material selection (304 SS pan, corrosion-resistant frame coating, sealed electronics) ensures compatibility with routine exposure to cleaning agents, particulate dust, and moderate thermal cycling (operating range: 10–40 °C, <80% RH non-condensing). The scale supports GLP/GMP-aligned documentation workflows through audit-trail-capable data export protocols.
Software & Data Management
The scale features native RS232 serial communication as standard, enabling direct integration with label printers, PLCs, and legacy MES systems. Optional USB (virtual COM port mode) and Ethernet (TCP/IP Modbus TCP or ASCII protocol) interfaces facilitate modern factory network integration—including connection to SCADA systems or centralized quality databases. All data transmission adheres to ASCII-based command-response structure for deterministic parsing. Firmware supports configurable auto-print triggers, timestamped batch logging, and user-accessible calibration lockout—supporting traceability requirements under FDA 21 CFR Part 11 when deployed with validated external software platforms.
Applications
- Production line checkweighing: Real-time verification of filled containers, blister packs, or assembled components against preset upper/lower limits.
- Inventory reconciliation: High-speed parts counting via unit weight averaging—validated for batches ranging from small fasteners to medium-sized consumer goods.
- Shipping manifest validation: Cumulative weight accumulation across multiple SKUs prior to palletization or carrier handoff.
- Raw material receipt inspection: Verification of supplier-provided lot weights against purchase order specifications.
- Work-in-progress (WIP) tracking: On-station mass recording at discrete process nodes for lean manufacturing analytics.
FAQ
What is the maximum capacity and readability of the i-D33P300B1V3ZH model?
The i-D33P300B1V3ZH is configured for 300 kg maximum capacity. Readability is determined by the selected firmware configuration and application mode—typically 10 g in standard weighing mode, consistent with OIML R76 Class III requirements.
Is the scale suitable for washdown environments?
No. While the load cell meets IP65 for dust and low-pressure water jets, the overall system—including the indicator housing and keypad—is not rated for full washdown. It is intended for dry, controlled industrial spaces.
Can the checkweighing color logic be customized beyond red/yellow/green?
The three-color LED backlight is fixed-function per hardware design. Tolerance thresholds (e.g., ±2%, ±5%) are fully programmable via front-panel menu navigation, but hue assignment is non-configurable.
Does the scale support automatic calibration or internal reference standards?
This model requires external calibration using certified test weights. It does not include motorized or internal calibration mechanisms.
What is the battery runtime on a full charge?
Under typical intermittent-use conditions (10–15 weigh cycles per hour), the integrated sealed lead-acid battery provides approximately 40–50 hours of operation. Runtime decreases significantly under continuous display backlighting or frequent data transmission.
