Overview
The OHAUS RC2000 Portable Counting Scale is an industrial-grade, battery-powered precision scale engineered for high-reliability piece-counting applications in manufacturing, warehousing, quality control, and inventory management environments. Unlike conventional platform scales, the RC2000 employs advanced load cell technology with digital signal processing to deliver stable, repeatable weight measurements—enabling accurate part counting based on user-defined sample unit weights. Its core functionality rests on the principle of *average piece weight (APW) calculation*: the scale determines the mean mass of a known reference quantity (e.g., 10–50 pieces), then extrapolates total piece count from bulk weight using real-time division algorithms. This method complies with ISO 8653:2016 (Industrial weighing—Counting scales—Metrological and technical requirements) and supports traceable, auditable counting workflows under GLP and GMP-aligned operational protocols.
Key Features
- Rechargeable lithium-ion battery providing up to 100 hours of continuous operation on a single charge—ideal for mobile use across production floors, receiving docks, and assembly lines.
- Large, backlit LCD display with intuitive icon-driven interface optimized for gloved-hand operation and low-light conditions.
- Dual-mode operation: standard weighing mode and dedicated counting mode with automatic APW calibration, tolerance-based reject alerts, and batch accumulation.
- Rugged ABS housing with IP54-rated ingress protection against dust and water splashes—suitable for non-hazardous industrial environments.
- Integrated RS-232 and USB Device ports for direct connection to PCs, label printers, or PLC systems; supports ASCII and Modbus RTU communication protocols.
- Auto-zero tracking and dynamic compensation for environmental drift ensure consistent accuracy across ambient temperature fluctuations (10–40 °C).
Sample Compatibility & Compliance
The RC2000 accommodates a broad range of discrete, uniform parts—including screws, washers, electronic components, pharmaceutical tablets, fasteners, and small machined parts—provided dimensional consistency and surface homogeneity meet ASTM E177-22 guidelines for measurement repeatability. It is certified to NTEP Class III (for commercial weighing up to 30 kg) and meets OIML R76-1:2021 requirements for non-automatic weighing instruments. All firmware and calibration routines are designed to support 21 CFR Part 11-compliant data integrity when integrated with validated laboratory information management systems (LIMS) or enterprise resource planning (ERP) platforms. Factory calibration certificates include as-found/as-left data and uncertainty budgets traceable to NIST standards.
Software & Data Management
The RC2000 operates natively without proprietary software but supports seamless integration via standard serial/USB protocols. When connected to host systems, it transmits timestamped weight, count, and status data—including over/under-tolerance flags, batch IDs, and operator codes—in structured ASCII frames. Optional OHAUS Acuity™ software (v3.2+) enables centralized configuration management, audit trail generation, electronic signature capture, and export to CSV, Excel, or SQL databases. All data logs retain immutable timestamps and support full forensic reconstruction for internal audits or regulatory inspections per ISO/IEC 17025:2017 clause 7.7.
Applications
- High-volume component kitting and line-side replenishment in automotive and electronics assembly.
- Pharmaceutical secondary packaging verification (e.g., blister pack count validation per USP ).
- Quality assurance sampling for incoming raw material lots (e.g., fastener counts per ANSI/ASQ Z1.4 sampling plans).
- Inventory reconciliation during cycle counts in distribution centers with barcode-triggered count initiation.
- Production line end-of-line (EOL) inspection for adherence to defined piece-per-container specifications.
FAQ
What is the maximum capacity and readability of the RC2000?
The RC2000 is available in multiple configurations; standard models offer capacities from 6 kg to 30 kg with readability ranging from 0.01 g to 1 g, depending on model variant. Exact specifications are detailed in the product datasheet corresponding to the selected SKU.
Does the RC2000 support external calibration with certified test weights?
Yes—the scale features internal calibration capability and accepts external calibration using Class M2 or better certified weights, following procedures outlined in OHAUS Technical Bulletin TB-RC2000-02.
Can counting tolerances be customized per job or part type?
Yes—users can define upper and lower count deviation thresholds (±0.1% to ±5.0%) independently for each stored application profile, enabling risk-based tolerance assignment aligned with criticality classification.
Is firmware update supported in-field?
Yes—firmware upgrades are delivered via USB flash drive using OHAUS Firmware Update Utility (v2.1+), with version rollback and checksum validation to ensure integrity.
How is data security maintained during transmission to host systems?
All serial and USB communications operate in plain-text ASCII format; encryption and authentication must be implemented at the host system level per organizational IT policy—no onboard cryptographic modules are embedded in the RC2000 hardware.
