Overview
The Defender® 6000 Washdown Scale – i-D61PW is an industrial-grade, high-protection weighing platform engineered for rigorous operational environments where hygiene, durability, and regulatory compliance are non-negotiable. Designed around the principles of precision load-cell transduction and robust environmental sealing, this scale employs a hermetically welded 316 stainless steel load cell compliant with both IP68 and IP69K ingress protection standards — enabling full resistance to high-pressure water jets, steam cleaning, and corrosive chemical exposure. Its structural architecture integrates food-grade polycarbonate housing for the indicator unit and 316 stainless steel for all wetted components including the U-frame base, weighing pan, support column, and mounting hardware (excluding 300 kg and 600 kg variants). Certified to NSF/ANSI Standard 18 — the benchmark for food equipment sanitation — the i-D61PW meets prerequisite requirements for HACCP-aligned production lines and supports GMP/GLP workflows in pharmaceutical manufacturing, bulk ingredient handling, and ready-to-eat food processing.
Key Features
- IP68 & IP69K-rated enclosure: Fully sealed against dust, immersion up to 1.5 m for 30 min (IP68), and resistant to high-temperature, high-pressure washdown cycles (up to 145 °C, 100 bar, 15 sec)
- NSF/ANSI 18 certified construction: Validated for direct contact with food products and compatibility with sanitary facility protocols
- 6-digit, 7-segment white-backlit LCD display with 45 mm character height for optimal legibility under ambient lighting or PPE-restricted viewing conditions
- Triple-color LED checkweighing bar (red/yellow/green) with programmable tolerance bands and real-time visual feedback
- 150% overload protection with mechanical stop design; automatic over/underload detection and audible/visual alerts
- Configurable environmental filtering: Adjustable digital damping to stabilize readings in vibrating or draft-prone environments
- GLP/GMP-compliant real-time clock with timestamped data logging capability (when paired with optional RS-232 or USB interface)
- Lockable keypad and menu system to prevent unauthorized parameter changes during operation
- Auto-zero tracking, auto-tare, auto-power-off, and low-battery indication — configurable via intuitive soft-key navigation
Sample Compatibility & Compliance
The i-D61PW accommodates diverse sample forms across primary and secondary packaging operations: bulk powders, liquid-filled containers, sealed trays, and irregularly shaped assemblies. Its 316 stainless steel pan and frame resist pitting from organic acids, chlorinated sanitizers (e.g., sodium hypochlorite), and alkaline cleaners used in CIP/SIP procedures. The scale conforms to ISO 9001 quality management requirements and supports audit readiness for FDA 21 CFR Part 11 (when integrated with compliant data capture software), EU Annex 11, and ICH Q7 GMP guidelines. It is routinely deployed in environments governed by SQF Code Edition 9, BRCGS Food Safety Issue 9, and FSSC 22000 v5.1.
Software & Data Management
While the i-D61PW operates as a standalone instrument, its serial (RS-232) and optional USB interfaces enable bidirectional communication with laboratory information management systems (LIMS), enterprise resource planning (ERP) platforms, and statistical process control (SPC) dashboards. When connected to OHAUS ACIS™ or third-party compliant middleware, the scale supports electronic record generation with user authentication, audit trail metadata (including operator ID, timestamp, weight value, and event type), and tamper-resistant data export in CSV or XML formats. Firmware updates are performed via USB drive, ensuring version traceability and validation documentation support.
Applications
- Food & beverage: In-line checkweighing of retail packages, batch reconciliation of raw material receipts, and portion control in cooking/prep stations
- Pharmaceuticals: Weighing of active pharmaceutical ingredients (APIs) during dispensing, container closure integrity verification, and formulation staging
- Chemicals: Hazardous material transfer verification, drum filling control, and catalyst dosage monitoring
- Logistics & distribution: Pallet accumulation verification, shipping manifest validation, and returnable asset tracking
- Contract manufacturing: Multi-client environment calibration traceability and SOP-driven operation mode selection
FAQ
What does IP69K certification mean for daily operation?
IP69K confirms that the scale can withstand repeated exposure to high-pressure, high-temperature water jets (80–100 °C, 80–100 bar) without degradation — essential for automated washdown cycles in USDA-inspected facilities.
Is the internal load cell replaceable in-field?
No — the 316 stainless steel load cell is permanently welded into the base structure to maintain IP69K integrity; replacement requires factory recalibration and re-certification.
Can the i-D61PW be integrated into a validated weighing network?
Yes — when configured with time-stamped output, user access controls, and electronic signature support via external software, it fulfills ALCOA+ data integrity criteria for regulated industries.
Does the scale support dynamic weighing of moving loads?
Yes — the Dynamic Weighing mode provides stabilized readings for conveyor-mounted applications, with adjustable response time and hold-trigger logic.
What battery life can be expected under typical usage?
With six AA alkaline cells, the indicator delivers approximately 200 hours of continuous operation at standard backlight intensity and sampling frequency.
