Defender® 6000 Washdown Stainless Steel IP69K Industrial Floor Scale

Overview

The Defender® 6000 Washdown is a high-integrity industrial floor scale engineered for continuous operation in hygienic and demanding production environments. Built to meet the rigorous demands of food processing, pharmaceutical manufacturing, and chemical handling, this scale integrates dual-certified ingress protection (IP68 and IP69K) with full 316 stainless steel construction — including sealed, welded load cells, corrosion-resistant frame, and NSF-certified indicator housing. Its measurement principle relies on precision strain-gauge transduction within a hermetically sealed sensor assembly, ensuring long-term stability and repeatability under repeated high-pressure washdown cycles. Unlike standard industrial scales, the Defender 6000 is validated for compliance with NSF/ANSI Standard 2 for food equipment, supporting HACCP prerequisite programs and enabling seamless integration into GMP-compliant workflows where environmental control, traceability, and contamination prevention are non-negotiable.

Key Features

• Hygienic Structural Integrity: Entire load-bearing architecture — pan, frame, column (except 300 kg and 600 kg variants), and indicator housing — fabricated from electropolished 316 stainless steel with crevice-free, weld-sealed joints to prevent microbial entrapment.
• Dual Ingress Protection: IP69K-rated for resistance to high-temperature, high-pressure steam jet cleaning (up to 100 bar, 80 °C); IP68-rated for submersion up to 1.5 m for 30 minutes — verified per DIN EN 60529.
• NSF-Certified Design: Third-party certified to NSF/ANSI 2, confirming suitability for direct contact with food, cleanability under industrial sanitation protocols, and absence of hazardous materials.
• Advanced Operator Interface: 6-digit, 20 mm white LED display with high-contrast readability under ambient lighting; 8×16 tri-color LED checkweighing matrix enabling intuitive pass/fail/reject visual feedback.
• Robust Overload Management: 150% mechanical overload protection integrated at both sensor and structural levels; automatic over/under-load alerts and stable-weight indication ensure process continuity and operator safety.
• Configurable Environmental Resilience: Adjustable digital filtering algorithms mitigate vibration-induced noise from nearby conveyors or agitators; user-lockable keypad and menu system prevent unauthorized configuration changes during shift handovers.

Sample Compatibility & Compliance

The Defender 6000 Washdown supports broad material handling requirements across regulated and unregulated production lines. It accommodates wet, viscous, particulate, and temperature-variable loads typical in meat processing, dairy batching, bulk chemical dispensing, and sterile pharmaceutical component weighing. Its sealed architecture eliminates harborage points for Listeria monocytogenes or Salmonella biofilm formation, satisfying prerequisite programs under ISO 22000 and BRCGS Food Safety Issue 9. The scale’s real-time clock and audit-trail-capable firmware (when paired with OHAUS ACIS or third-party GLP/GMP-compliant software) support ALCOA+ data integrity principles. All firmware revisions undergo validation documentation per ICH Q9 and are compatible with 21 CFR Part 11-compliant electronic signature workflows when deployed with appropriate access controls and electronic record archiving.

Software & Data Management

• Standard RS232 and USB host ports enable direct connection to label printers, PLCs, or local PCs for raw weight capture.
• Optional Ethernet/Wi-Fi modules support MQTT or Modbus TCP integration into MES/SCADA systems (e.g., Siemens SIMATIC, Rockwell FactoryTalk).
• GLP/GMP real-time clock enables time-stamped event logging (zero, tare, print, mode change) with optional password-protected user roles.
• User-defined print templates support custom formatting for batch records, shipping manifests, or QC check sheets — compliant with internal SOPs and external auditor expectations.
• Data export via CSV or XML formats ensures compatibility with LIMS platforms such as LabWare or Thermo Fisher SampleManager.

Applications

This scale serves mission-critical functions across multiple operational stages: raw material receipt verification with APW-optimized counting for fasteners or vials; in-process checkweighing of filled pouches or trays against dynamic tolerance bands; dynamic filling control with hold-and-stabilize logic for liquid or semi-solid dosing; inventory reconciliation in cold/wet warehouse zones; and final pallet verification prior to dispatch. Its durability and certification profile make it suitable for USDA-inspected facilities, EU-regulated food exporters (EC No. 852/2004), and FDA-audited API manufacturing suites operating under cGMP Annex 11 requirements.

FAQ

Is the Defender 6000 Washdown certified for use in USDA-inspected meat and poultry facilities?
Yes — its NSF/ANSI 2 certification and 316 stainless steel construction meet USDA-FSIS Directive 7120.1 requirements for equipment used in official establishments.
Can the scale maintain calibration accuracy after repeated IP69K washdown cycles?
Calibration stability is ensured by welded, hermetically sealed 316 SS load cells with zero-drift compensation algorithms; routine verification using traceable test weights is recommended per ASTM E74 and ISO/IEC 17025.
Does the optional Wi-Fi module support WPA3 encryption and enterprise authentication (802.1X)?
Yes — the OHAUS Wi-Fi adapter supports WPA3-Enterprise with RADIUS server integration, enabling secure onboarding into corporate VLANs without compromising network segmentation policies.
Is the tri-color LED checkweighing display programmable for multi-zone tolerancing (e.g., ±0.5 g, ±1.0 g, ±2.0 g)?
Yes — up to three independent tolerance bands can be defined per weighing session, with distinct LED color assignments (green/yellow/red) and configurable audible alerts.
Are firmware updates provided with validation documentation for GxP environments?
OHAUS supplies IQ/OQ protocol templates and change control records for all major firmware releases, supporting customer-executed validation per GAMP 5 guidelines.
