Overview
The OHAUS Defender 3000 i-D33P is a robust, NTEP-certified industrial platform scale engineered for high-reliability weighing in production, packaging, warehousing, and logistics environments. Built upon OHAUS’ proven Defender 3000 platform architecture, the i-D33P integrates precision load cell technology with an ergonomic, operator-centric interface to deliver consistent performance under demanding daily use. Its measurement principle relies on electromagnetic force compensation (EMFC) for the indicator unit, coupled with a high-stability aluminum alloy load cell rated to IP65 ingress protection—ensuring accurate signal transduction even in dusty or mildly humid conditions typical of dry industrial settings. The scale meets Class III accuracy requirements per NTEP Handbook 44 and conforms to OIML R76-1 standards for non-automatic weighing instruments, making it suitable for legal-for-trade applications where traceability and repeatability are mandated.
Key Features
- 600 kg maximum capacity with 0.2 kg readability, optimized for medium-to-heavy industrial loads including palletized goods, bulk containers, and assembled components.
- Multicolor backlit LCD display (45 mm digit height) with tri-color checkweighing indicators (red/yellow/green) enabling rapid visual pass/fail assessment without operator interpretation delay.
- Stainless steel 304 weighing pan and powder-coated square-tube carbon steel frame provide mechanical resilience against impact, corrosion, and repeated loading cycles.
- IP67-rated pan and frame assembly ensures resistance to water jets and particulate ingress during cleaning or incidental spill exposure.
- Tactile mechanical keypad offers reliable actuation in gloved-hand operation; ABS engineering plastic housing provides thermal stability and impact resistance across –10 °C to +40 °C operating range.
- Dual-power architecture supports continuous operation via universal AC input (110–240 VAC) or up to 8 hours of battery-backed runtime using integrated sealed lead-acid battery.
- Modular mounting system with adjustable U-shaped metal bracket allows flexible installation on floors, benches, or integrated into conveyor lines.
Sample Compatibility & Compliance
The i-D33P accommodates diverse sample forms—including rigid crates, polybags, tote bins, and irregularly shaped assemblies—without requiring recalibration. Its large pan surface (600 × 800 mm standard) minimizes off-center loading errors, while the square-tube structural design maintains rigidity at full capacity. Regulatory alignment includes NTEP Class III certification (Certificate No. 22-022E), OIML R76-1 compliance for metrological equivalence in international trade, and adherence to ISO 9001 quality management systems at OHAUS’ Shanghai manufacturing facility. All firmware and calibration routines support audit-ready documentation per GLP/GMP guidelines, with optional configuration for FDA 21 CFR Part 11-compliant electronic records when paired with OHAUS Acquire™ software.
Software & Data Management
The scale supports bidirectional data exchange via standard RS232 serial protocol, enabling seamless integration with label printers (e.g., Zebra GK420t), PLCs, and MES platforms. Optional USB Type-B and Ethernet interfaces allow direct connection to Windows-based workstations or industrial networks. When used with OHAUS Acquire™ PC software (v5.0+), users gain access to configurable data logging, automated report generation (CSV/PDF), user-access-level controls, and secure audit trails—including timestamped calibration events, weight history, and parameter change logs. Firmware updates are performed via USB drive without external service tools, ensuring long-term maintainability.
Applications
- Production line checkweighing of pre-packed consumer goods to verify fill consistency against target weight tolerances.
- Inventory reconciliation of raw materials and finished goods using counting mode with automatic piece-weight averaging.
- Shipping manifest verification via accumulation mode—summing sequential weights for consolidated pallet or container loads.
- Quality control sampling in pharmaceutical secondary packaging, food processing, and automotive component staging.
- Warehouse receiving inspection where rapid, legally compliant weight validation is required prior to stock entry.
FAQ
Is the i-D33P certified for trade use in North America?
Yes—the i-D33P600B1V3ZH model carries NTEP Certificate of Conformance #22-022E for Class III applications up to 600 kg.
What environmental protections does the scale offer?
The indicator is rated IP65; the pan and frame assembly meet IP67 requirements per IEC 60529, supporting washdown-capable deployment in controlled dry industrial zones.
Can the scale be integrated into an existing factory network?
With optional Ethernet interface and TCP/IP stack support, the i-D33P enables Modbus TCP communication and direct SCADA/MES connectivity.
Does the device support user-defined tolerance bands in checkweighing mode?
Yes—up to three programmable tolerance zones (underweight, target, overweight) with independent color assignment and audible alert options.
How is calibration performed, and is it traceable?
Internal calibration uses certified test weights; external calibration follows ISO/IEC 17025 procedures. Calibration certificates include uncertainty budgets and reference to national standards (NIST-traceable).
