Overview
The Defender® 6000 Washdown Scale (i-D61PW) is an industrial-grade, high-protection weighing platform engineered for rigorous hygienic environments where moisture, chemical exposure, and frequent high-pressure cleaning are routine. Built to meet the dual ingress protection standards of IP68 and IP69K, this scale employs a fully sealed mechanical architecture—including hermetically welded 316 stainless steel load cells—and food-grade polycarbonate housing for the indicator unit. Its design complies with NSF/ANSI Standard 18 for food equipment, supporting HACCP-aligned process control in regulated manufacturing settings. The scale operates on the principle of strain-gauge-based force transduction, delivering stable, repeatable mass measurements under dynamic operational conditions typical of production lines, packaging stations, and warehouse dispatch zones.
Key Features
- IP68 & IP69K-rated enclosure: Fully submersible (up to 1 m for 30 min) and resistant to high-temperature, high-pressure washdown cycles (up to 80°C, 100 bar, 15° spray angle)
- Hygienic construction: 316 stainless steel pan, frame, and upright column (excluding 300 kg and 600 kg variants); NSF-certified food-grade PC indicator housing
- Robust overload protection: 150% rated capacity safeguard with audible/visual over/underload alerts
- Intuitive 6-digit, 7-segment white-backlit LCD display (45 mm character height) with real-time stability indicator
- Triple-color LED checkweighing bar (red/yellow/green) for immediate visual pass/fail feedback
- Configurable environmental filtering: Adjustable digital damping to suppress vibration or air current interference
- Secure operation controls: Keypad and menu lockout; auto-tare, auto-print, auto-off, and low-battery warnings
- Power flexibility: Standard 6× AA alkaline battery operation (approx. 1,000 hours continuous use); optional magnetic infrared communication kit for wireless data transfer
Sample Compatibility & Compliance
The i-D61PW accommodates a wide range of bulk, packaged, and irregularly shaped items common in food processing, chemical blending, and pharmaceutical secondary packaging operations. Its large, smooth-surface 316 stainless steel pan minimizes residue retention and supports rapid sanitization between batches. All wetted surfaces conform to FDA 21 CFR §177.1580 (food-contact plastics) and EU Regulation (EC) No. 1935/2004. The integrated real-time clock enables GLP/GMP-compliant audit trails when paired with OHAUS Logger Pro™ or third-party LIMS systems. The scale meets ISO/IEC 17025 calibration traceability requirements and supports documented verification per ASTM E74, USP , and EN 45501.
Software & Data Management
Data output is supported via RS-232 and optional infrared interface, enabling seamless integration with MES, ERP, and quality documentation platforms. The scale natively supports standard ASCII and Modbus RTU protocols. When connected to OHAUS’ certified software suite, users gain access to electronic signature capability, user-level permission management, and 21 CFR Part 11–compliant audit logging—including timestamped records of zeroing, taring, calibration, and weight capture events. All configuration changes are logged with operator ID and reason-for-change fields, fulfilling ALCOA+ data integrity principles.
Applications
- Food & beverage: In-line checkweighing of filled pouches, trays, and cartons; batch ingredient dispensing with APW-optimized counting
- Pharmaceuticals: Weighing of excipients and final dosage forms during packaging; GMP-aligned inventory reconciliation
- Chemicals: Corrosive material handling in solvent-based manufacturing; drum and tote filling verification
- Logistics & warehousing: Palletized load verification prior to shipment; dynamic weighing of moving conveyors (with optional hold function)
- Quality assurance labs: Routine verification of calibrated weights and reference standards in humidified test chambers
FAQ
What does IP69K certification mean for daily operation?
IP69K certifies resistance to high-pressure, high-temperature water jets—enabling full sanitization without disassembly. It exceeds standard IP67/IP68 requirements and is mandatory for USDA-inspected meat/poultry facilities.
Is calibration traceable to national standards?
Yes—OHAUS provides NIST-traceable calibration certificates upon request. Internal calibration routines support adjustment using certified test weights meeting OIML R111 Class M2 tolerances.
Can the scale be integrated into a validated manufacturing system?
Yes—when used with OHAUS-certified software and documented procedures, it satisfies FDA 21 CFR Part 11, EU Annex 11, and ISO 13485 requirements for electronic records and signatures.
What maintenance intervals are recommended for washdown environments?
Visual inspection before each shift; full external wipe-down after every cleaning cycle; annual verification of load cell integrity and indicator firmware version by authorized service personnel.
Does the indicator support multiple languages for global deployment?
Yes—the embedded firmware includes English, Spanish, French, German, Chinese, Japanese, and Korean language options, configurable via setup menu.
