Overview
The Defender® 6000 Washdown Scale (i-D61PW) is an industrial-grade, high-protection weighing platform engineered for rigorous hygienic environments. Designed according to the principles of load cell-based force measurement under static equilibrium conditions, it delivers stable, repeatable mass readings in dynamic production settings where moisture, chemical exposure, and frequent sanitation cycles are routine. Its dual IP68 and IP69K ingress protection ratings—certified per IEC 60529—ensure full operational integrity during high-pressure, high-temperature washdown procedures using steam, caustic cleaners, or food-grade sanitizers. This makes the scale suitable for continuous use in wet-process zones compliant with HACCP, FDA 21 CFR Part 11 (when integrated with validated software), and EU Regulation (EC) No. 852/2004 on food hygiene.
Key Features
- IP68/IP69K-rated stainless steel load cell with hermetically welded 316 stainless steel housing, eliminating internal moisture accumulation and corrosion pathways
- Hygienic mechanical architecture: U-shaped 316 stainless steel support frame, seamless 316 stainless steel weighing pan and column (excluding 300 kg and 600 kg variants), and food-grade polycarbonate indicator housing compliant with NSF/ANSI Standard 18
- 6-digit, 7-segment white-backlit LCD display with 45 mm character height for high-visibility reading under ambient lighting or gloved operation
- Triple-color LED checkweighing bar (red/yellow/green) with programmable tolerance thresholds and visual status feedback
- 150% overload protection with audible and visual over/underload alerts, low-battery indication, auto-zero tracking, and auto-tare functionality
- Configurable environmental filtering (digital damping), stability detection algorithm, and user-lockable keypad/menus to prevent unauthorized parameter changes
- Integrated real-time clock supporting GLP/GMP-compliant data traceability, including time-stamped weight records and operator ID logging when paired with OHAUS Acuity™ or third-party LIMS
Sample Compatibility & Compliance
The i-D61PW accommodates a broad range of bulk, packaged, and irregularly shaped items typical in food processing (e.g., meat trays, baked goods, dairy containers), pharmaceutical secondary packaging (blister packs, vials on trays), and chemical intermediate handling (drums, totes, IBCs). Its sealed construction eliminates crevices that harbor microbial growth, satisfying prerequisite design criteria outlined in ISO 22000:2018 and BRCGS Food Safety Issue 9 Section 4.11. The scale has received formal NSF certification (Certificate #170723-01), verifying conformance to NSF/ANSI 18 for food equipment materials and cleanability. All electrical components meet UL 61010-1 and CE marking requirements for industrial instrumentation.
Software & Data Management
Data output is supported via RS-232 serial interface as standard; optional magnetic infrared communication enables cable-free data transfer to PCs or printers without physical port exposure—critical for maintaining IP69K integrity during operation. When connected to OHAUS Acuity™ Software or compatible SCADA/HMI systems, the scale supports audit-trail-enabled data capture, electronic signature workflows, and automated report generation aligned with 21 CFR Part 11 Annex 11 expectations. User-defined print templates (including batch ID, timestamp, operator code, and pass/fail status) can be triggered manually or automatically upon stabilization.
Applications
- Food manufacturing: In-line checkweighing of retail-ready packages prior to case packing; portion control verification in deli and ready-meal lines
- Pharmaceutical production: Weighing of excipients and active ingredients during dispensing; final container checkweighing in packaging suites
- Chemical blending operations: Batch ingredient addition verification under ATEX Zone 22-compatible conditions (non-explosive dust environments)
- Distribution centers: Palletized load verification pre-shipment; inventory reconciliation in refrigerated or humid warehouse zones
- Contract manufacturing organizations (CMOs): Multi-client environment support via configurable user profiles and role-based access control
FAQ
What does IP69K certification mean for daily operation?
IP69K certifies resistance to high-pressure, high-temperature water jets (up to 100 bar, 80 °C) directed at angles from 0° to 180°, ensuring uninterrupted function after aggressive cleaning cycles.
Is the scale compatible with GMP documentation requirements?
Yes—when used with time-stamped data logging and operator authentication protocols, it supports ALCOA+ data integrity principles and satisfies core elements of Annex 11 validation for computerized systems.
Can the display be viewed clearly while wearing safety goggles or in steam-filled environments?
The 45 mm high-contrast white-backlit LCD, combined with anti-fog optical coating on the polycarbonate lens, maintains legibility under condensation and PPE constraints.
Does the stainless steel construction resist common food-grade sanitizers such as peracetic acid or sodium hypochlorite?
Yes—316 stainless steel exhibits superior pitting and crevice corrosion resistance in oxidizing chloride-rich environments typical of chlorine-based and peroxyacid sanitizers.
How is calibration traceability maintained in regulated environments?
Internal calibration routines support external verification using NIST-traceable weights; calibration events—including date, technician ID, and deviation values—are stored locally and exportable via serial interface.
