Adam ABW-S Stainless Steel Waterproof Bench Scale

Overview

The Adam ABW-S Stainless Steel Waterproof Bench Scale is an industrial-grade weighing instrument engineered for high-reliability operation in demanding wet, dusty, or hygienically sensitive environments. Built to the IP68 ingress protection standard, it withstands full submersion in water up to 1 meter for 30 minutes and resists fine particulate ingress—making it suitable for food processing lines, pharmaceutical cleanrooms, chemical formulation areas, and outdoor logistics hubs where washdown protocols or ambient moisture are routine. Its monolithic 304 stainless steel housing integrates a sealed membrane keypad and dual-position LED displays, enabling simultaneous front- and rear-facing readouts for collaborative workflows or pass-through station configurations. The scale operates on either AC power via a regulated 12 VDC 800 mA adapter or its internal rechargeable battery—delivering up to 80 hours of continuous operation on a single charge—ensuring uninterrupted use during shift transitions or mobile deployment.

Key Features

• IP68-rated enclosure: Fully sealed against dust and temporary immersion; compliant with IEC 60529 for environmental robustness.
• Dual LED display system: Front display with 20 mm digits and rear display with 15 mm digits support bidirectional visibility without repositioning the unit.
• High-resolution counting capability: Internal resolution of 1:600,000 enables precise piece-counting applications, including small electronic components, fasteners, and tablets.
• Auto-part-weight optimization: Dynamically calculates average part weight during loading using statistical averaging across multiple samples—reducing operator dependency and improving repeatability.
• Overload protection circuitry: Integrated mechanical and electronic safeguards prevent damage from accidental overloading beyond rated capacity.
• “Hide-until-activated” indicator logic: Status LEDs remain unlit until triggered by active weighing or function selection—minimizing visual distraction and enhancing focus on critical tasks.
• External calibration compatibility: Supports traceable calibration using certified weights; meets requirements for ISO/IEC 17025-compliant calibration intervals.

Sample Compatibility & Compliance

The ABW-S accommodates a broad range of sample types—from bulk powders and packaged goods to irregularly shaped industrial parts—without compromising accuracy or structural integrity. Its stainless steel platform and sealed load cell assembly resist corrosion from saline solutions, cleaning agents (e.g., sodium hypochlorite, peracetic acid), and organic solvents commonly used in regulated manufacturing. The device complies with European CE marking directives (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU), RoHS 2011/65/EU, and conforms to relevant sections of NTEP Handbook 44 for commercial weighing applications in North America. While not intrinsically rated for hazardous locations, its construction supports integration into Class I, Division 2 or ATEX Zone 2 environments when installed per local electrical codes.

Software & Data Management

The ABW-S operates as a standalone instrument with no embedded firmware-based data logging or USB/Bluetooth connectivity. All configuration, unit selection, and counting parameters are managed directly via the sealed keypad interface. For traceability and quality documentation, users may integrate the scale with external data acquisition systems via RS-232 serial output (optional cable required). When connected to validated laboratory information management systems (LIMS) or enterprise resource planning (ERP) platforms, the scale supports GLP/GMP-aligned workflows—including user-defined ID entry, timestamped weight capture, and audit-ready export of raw measurement records. External calibration events can be manually logged in accordance with FDA 21 CFR Part 11 requirements when paired with appropriate electronic signature controls.

Applications

• Batch verification and ingredient reconciliation in GMP-compliant pharmaceutical and nutraceutical production.
• High-volume parts counting in electronics assembly and automotive component distribution centers.
• Portion control and yield tracking in USDA-inspected meat and seafood processing facilities.
• Inventory management of consumables in hospital central supply departments (CSD) and sterile processing units (SPD).
• Field-deployable weighing for municipal waste sorting operations and recycling facility inbound inspection.
• Quality assurance sampling in beverage bottling lines subject to frequent CIP/SIP cycles.

FAQ

Is the ABW-S certified for trade use (e.g., NTEP or MID)?
No—the ABW-S is designed for industrial process control and internal quality assurance, not legal-for-trade commercial transactions. It does not carry NTEP Certificate of Conformance or MID approval.
Can the internal battery be replaced by the user?
Yes—the rechargeable battery is field-replaceable using standard service tools; replacement kits and torque specifications are documented in the maintenance manual provided with each unit.
What is the recommended recalibration interval?
Adam Instruments recommends external calibration at least once per shift in high-usage environments, or daily prior to first use in regulated settings—aligned with ISO 9001 clause 7.1.5 and ASTM E899-20 guidance for weighing equipment verification.
Does the scale support tare memory or multiple preset tare values?
No—the ABW-S implements a single, volatile tare function that resets upon power cycle; it does not store tare offsets or support programmable presets.
Is the LED display brightness adjustable?
No—display intensity is fixed to ensure consistent readability under variable ambient lighting conditions, including direct sunlight and low-illumination warehouse zones.
