OHAUS Defender 3000 i-D33P300B1X2ZH Industrial Platform Scale

Overview

The OHAUS Defender 3000 i-D33P300B1X2ZH is an industrial-grade platform scale engineered for high-reliability weighing tasks in manufacturing, packaging, warehousing, and logistics operations. Built upon OHAUS’ proven Defender 3000 platform architecture, this model integrates a robust mechanical design with intuitive operator interface functionality to support routine mass measurement under demanding non-hazardous industrial conditions. Its core transduction system employs a hermetically sealed aluminum load cell rated to IP65 — ensuring resistance to dust ingress and low-pressure water jets — while maintaining long-term stability and repeatability across temperature fluctuations typical of factory floors. The scale operates on dual power sources: a universal-input AC adapter (110–240 VAC, 50/60 Hz) and an integrated rechargeable lead-acid battery, enabling uninterrupted operation during temporary power outages or mobile deployment within defined dry zones.

Key Features

• Large-format, 6-digit, 7-segment multicolor backlit LCD display with 45 mm digit height — optimized for legibility in ambient lighting ranging from dim storage areas to brightly lit production lines.
• Three-color visual checkweighing feedback (red/yellow/green) directly mapped to user-defined tolerance bands — eliminates subjective interpretation and accelerates pass/fail decisions during inline quality control.
• Durable mechanical construction: 304 stainless steel weighing pan; square-tube carbon steel frame with epoxy powder coating; corrosion-resistant ABS polymer housing for the indicator unit; rigid U-shaped metal mounting bracket for wall, pedestal, or benchtop installation.
• Four primary weighing modes: standard weighing, parts counting, checkweighing, and accumulation — each accessible via tactile membrane keys with positive actuation feedback.
• Standard RS232 serial interface supports connection to label printers, PLCs, or legacy industrial PCs; optional USB or Ethernet modules enable integration into modern MES or ERP systems with configurable data formatting (e.g., ASCII, Modbus RTU/TCP).
• Internal battery management system provides real-time charge status indication and automatic low-power mode activation to extend operational runtime between charges.

Sample Compatibility & Compliance

The i-D33P300B1X2ZH is designed exclusively for solid, non-corrosive, non-explosive materials within dry industrial settings. It is not intended for use with liquids, powders prone to airborne dispersion, or applications requiring washdown capability (IP67/IP69K). The scale meets electromagnetic compatibility requirements per EN 61326-1 and safety standards under EN 61010-1. As a CE-marked instrument manufactured in an ISO 9001-certified facility in Shanghai, it complies with RoHS Directive 2011/65/EU regarding hazardous substance restrictions. While not certified for legal-for-trade use (e.g., NTEP, EC Type Approval), its performance aligns with ASTM E74 and ISO/IEC 17025 guidelines for verification of non-automatic weighing instruments used in internal process control and inventory management.

Software & Data Management

No proprietary software is required for basic operation. All configuration — including units, decimal places, checkweighing thresholds, counting sample size, and communication parameters — is performed locally via the front-panel keypad. RS232 output follows standard ASCII protocol with customizable delimiters and carriage-return/line-feed termination. When equipped with the optional Ethernet module, the scale supports TCP/IP socket communication and can be assigned a static or DHCP-assigned IP address. Audit trails are not natively supported; however, external systems receiving transmitted data may implement timestamped logging compliant with 21 CFR Part 11 if deployed within validated pharmaceutical or medical device quality systems. Firmware updates are delivered via USB flash drive using OHAUS-provided utilities.

Applications

This platform scale serves as a foundational measurement node in discrete manufacturing workflows where traceability, throughput, and ergonomic efficiency are prioritized over metrological grade certification. Typical deployments include: raw material receipt verification against purchase orders; component counting prior to assembly line feeding; final package checkweighing before palletization; dynamic accumulation of batch weights during kitting operations; and periodic calibration verification of higher-accuracy instruments using certified test weights. Its modular interface options facilitate seamless data capture into SAP WM, Oracle WMS, or custom SQL-based warehouse tracking platforms without middleware dependency.

FAQ

Is the i-D33P300B1X2ZH approved for trade use or legal metrology?
No. This model is designated for industrial process control only and does not carry NTEP, MID, or OIML certification.
What is the maximum overload capacity of the load cell?
The aluminum load cell is rated for 150% of full-scale capacity (450 kg) without permanent deformation, per manufacturer specifications.
Can the display brightness or backlight timeout be adjusted?
Yes — both parameters are configurable through the setup menu using the front-panel keys.
Does the scale support dynamic weighing (e.g., weighing on a conveyor)?
No. It is designed for static loading only and lacks vibration compensation or motion filtering algorithms.
Is the lead-acid battery user-replaceable?
Yes — the battery compartment is accessible via two Phillips screws on the rear panel, and replacement kits are available through OHAUS authorized service channels.
