METTLER TOLEDO ICS689 Intelligent Floor Scale

Overview

The METTLER TOLEDO ICS689 Intelligent Floor Scale is an industrial-grade, hygienic weighing platform engineered for high-reliability operation in regulated production environments—including food processing, pharmaceutical manufacturing, and fine chemical synthesis. Built upon METTLER TOLEDO’s legacy of metrological excellence, the ICS689 implements precision strain-gauge load cell technology with dual-sealed, IP68/IP69K-rated electronics—ensuring uninterrupted performance under repeated high-pressure washdowns, steam sterilization, and corrosive exposure. Its fully welded AISI 304 stainless steel (1.4301) construction complies with EHEDG Document 8 and NSF/ANSI Standard 2 for equipment used in food-contact zones. Unlike conventional floor scales, the ICS689 integrates real-time weight-based decision logic directly into the weighing terminal—eliminating latency between measurement and action in checkweighing, filling, or counting workflows.

Key Features

• IP68/IP69K-certified weighing indicator with patented double-seal architecture—validated for continuous operation in wet, caustic, or temperature-cycling environments
• Full 304 stainless steel frame and pan; no crevices, no weld seams requiring polishing—designed for rapid, validated cleaning per FDA and EU GMP Annex 1 requirements
• ColorWeight™ visual feedback system: intuitive color-coded display (green/yellow/red) indicating pass/fail status against user-defined tolerance bands—reducing operator interpretation error by >40% in validation studies
• Configurable soft-key interface with alphanumeric input support (including Simplified Chinese), enabling direct entry of batch IDs, material codes, or operator credentials without external peripherals
• Embedded Alibi memory storing 300,000 auditable weighing transactions—including timestamp, weight value, operator ID, and calibration event logs—meeting ISO/IEC 17025 traceability and 21 CFR Part 11 electronic record integrity requirements
• Multi-protocol scale interface supporting analog (mV/V), IDNet®, and SICSpro® load cells—enabling seamless integration with legacy and next-generation METTLER TOLEDO weighing modules

Sample Compatibility & Compliance

The ICS689 is purpose-built for heterogeneous industrial samples—from bulk powders and viscous slurries to pre-packaged unit-dose containers and sterile intermediate batches. Its modular design supports up to four strain-gauge load cells (including PBK7, PBK9, and PFK9 series), accommodating total capacities from 30 kg to 3,000 kg with resolution down to 0.264 µV/e. All configurations are certified to OIML R76 (Class III), NTEP Class III, and CMC standards, with metrological data (e.g., verification scale interval ‘e’, maximum capacity, accuracy class) permanently displayed on-screen during operation. The system meets EHEDG Guideline 8 for hygienic design and NSF/ANSI 2 for food equipment sanitation. For GxP environments, firmware supports audit-trail-enabling features including user authentication, role-based access control, and immutable calibration history export—facilitating routine internal audits and regulatory inspections (e.g., FDA Form 483 readiness).

Software & Data Management

The ICS689 operates on METTLER TOLEDO’s proprietary embedded OS, supporting over-the-air firmware updates and configurable application profiles via the free Standard Weighing Software Suite. Data export is natively supported via RS232 (ASCII/MT-S format), Ethernet (TCP/IP Modbus TCP), or optional USB host (CSV/Excel). When connected to METTLER TOLEDO’s LabX® Scale Edition or third-party MES/ERP systems (e.g., SAP EWM, Siemens SIMATIC IT), the scale transmits structured JSON payloads containing weight metadata, process flags, and digital signatures—ensuring ALCOA+ compliance (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Internal database stores up to 5,000 material records with tare offsets, density factors, and target weights—enabling rapid recipe recall and reducing setup time by up to 65% in multi-product lines.

Applications

• Pharmaceutical Blending & Filling: Real-time weight monitoring during granule transfer, capsule filling, or vial dosing—with automatic rejection triggers based on USP <41> weight variation limits
• Food Portion Control: High-speed checkweighing of cooked meats, baked goods, or ready-to-eat meals—integrated with vision inspection systems via digital I/O for synchronized reject actuation
• Chemical Drum Weighing: Corrosion-resistant platform for hazardous material dispensing; certified for use in Zone 22 dust environments per IECEx/ATEX directives
• Warehouse Reconciliation: Inventory reconciliation with barcode scanning (via optional USB scanner), auto-updating ERP stock levels with full traceability to weigh event and operator
• GMP Batch Release: Automated generation of electronic batch records (EBR) compliant with Annex 11, including weight deviation analysis and electronic signature capture

FAQ

Does the ICS689 meet FDA 21 CFR Part 11 requirements for electronic records and signatures?
Yes—the device supports audit-trail logging, user authentication, and electronic signature capture when paired with METTLER TOLEDO LabX Scale Edition or validated third-party LIMS/MES platforms.
Can the ICS689 be integrated into a Siemens SIMATIC PCS 7 DCS environment?
Yes—via optional Modbus TCP or OPC UA communication modules, enabling bidirectional data exchange with plant-level automation systems.
What is the minimum detectable weight change under dynamic checkweighing conditions?
The system achieves repeatability of ≤0.5e under standard operating conditions (Class III, 23 ±2 °C, ≤60% RH), consistent with OIML R76 test protocols.
Is the internal Alibi memory encrypted and tamper-proof?
Alibi data is stored in write-once flash memory with hardware-enforced write protection; export requires authenticated administrative access and generates SHA-256 hash-verified archives.
Does the ICS689 support remote diagnostics and predictive maintenance alerts?
With optional WLAN and METTLER TOLEDO Remote Service subscription, the scale transmits health metrics (load cell drift, temperature gradient, power stability) to cloud analytics dashboards—enabling proactive service dispatch before failure thresholds are reached.
