OHAUS TCS-D51XW15WR3 IP66 Waterproof Stainless Steel Bench Scale

Overview

The OHAUS TCS-D51XW15WR3 is a high-reliability, IP66-rated stainless steel bench scale engineered for demanding industrial, pharmaceutical, and food processing environments where washdown capability, regulatory traceability, and operational consistency are critical. Built on OIML R76 Class III metrological principles, the scale employs electromagnetic force restoration (EMFR) sensing technology—ensuring stable, drift-resistant measurement performance across temperature fluctuations and mechanical vibration. Its 15 kg maximum capacity and 1 g readability meet standard requirements for intermediate-precision weighing tasks in quality control laboratories, production line checkweighing stations, and raw material receiving areas. The scale’s design prioritizes long-term repeatability (>99.9% 24-hour stability under controlled conditions) and mechanical robustness, with all load-bearing components fabricated from electropolished 304 stainless steel to resist corrosion from cleaning agents, saline solutions, and organic solvents.

Key Features

• Full 304 stainless steel construction—including pan, housing, and internal structural frame—for sustained resistance to moisture, caustic cleaners, and microbial growth.
• IP66 ingress protection rating certified per IEC 60529: dust-tight and resistant to powerful water jets (12.5 mm nozzle, 100 kPa, 3 minutes from any direction), enabling safe use in wet-process zones and frequent sanitation cycles.
• Backlit wide-angle LCD display (128 × 64 pixels) with adjustable contrast and auto-dimming logic—optimized for visibility under ambient lighting ranging from 50 to 10,000 lux.
• Multi-mode weighing firmware supporting six validated operational modes: static weighing, checkweighing with configurable hi/lo/tol limits, piece counting (with automatic sample size recalculation), percentage weighing relative to reference mass, dynamic weighing for unstable loads, and manual hold activation.
• Dual-power architecture: integrated rechargeable Ni-MH battery (up to 120 hours continuous operation) and universal AC adapter input (100–240 VAC, 50/60 Hz), eliminating downtime during power transitions.
• Standard RS232 serial interface compliant with ANSI/EIA-232-F specifications, transmitting timestamped weight data (including date, time, unit, and mode identifier) in ASCII format—fully compatible with LIMS, MES, and electronic batch record systems.

Sample Compatibility & Compliance

The TCS-D51XW15WR3 accommodates containers and samples up to 200 mm × 250 mm footprint without compromising accuracy. Its low-profile pan geometry minimizes center-of-gravity shift during off-center loading, maintaining linearity within ±0.002% of full scale across 80% of pan surface area. The scale is certified to OIML R76-1:2021 (Class III) and NTEP Certificate #22-012A for legal-for-trade applications in the United States. It supports GMP and GLP workflows through built-in audit trail capabilities: all calibration events, parameter changes, and user logins are time-stamped and stored locally (non-volatile memory, 10,000-event capacity). While not inherently 21 CFR Part 11 compliant, its data export structure enables integration with validated third-party software platforms that provide electronic signature, role-based access control, and change history reporting.

Software & Data Management

No proprietary software installation is required for basic data capture; the scale operates as a virtual COM port device. For enhanced traceability, OHAUS provides optional StarCom™ PC software (v3.2+), which enables automated report generation (PDF/CSV), statistical process control (SPC) charting, and configurable data filtering by operator ID, time range, or weighing mode. All transmitted records include embedded metadata: scale ID, firmware version, UTC timestamp (synced via host PC), and environmental status flags (e.g., “Stable”, “Unstable”, “Overload”). Data streams conform to ASTM E1921-22 formatting guidelines for analytical instrument outputs, facilitating direct ingestion into enterprise quality management systems (QMS).

Applications

• Pharmaceutical manufacturing: Raw material receipt verification, in-process blend uniformity checks, and final packaging weight audits per USP and EU Annex 11 requirements.
• Food & beverage production: Batch ingredient dosing, portion control validation, and HACCP-critical checkweighing at metal detection or labeling stations.
• Chemical formulation labs: Precise additive dispensing where solvent exposure mandates frequent decontamination.
• Contract manufacturing organizations (CMOs): Multi-client environment support via password-protected user profiles and segregated data directories.
• Academic research facilities: Teaching labs requiring durable, intuitive instrumentation for metrology fundamentals and quality assurance coursework.

FAQ

Is the TCS-D51XW15WR3 suitable for outdoor use?
No—it is rated IP66 for washdown and dust resistance but lacks UV stabilization, condensation management, or thermal compensation for uncontrolled ambient conditions. Indoor, climate-stabilized environments are required.
Can the scale be calibrated internally without external weights?
Yes—internal calibration is supported via integrated motor-driven calibration mass; however, external verification using traceable Class M2 weights is required per ISO/IEC 17025 before first use and after any impact event.
Does the RS232 interface support bi-directional communication?
The standard interface is unidirectional (scale-to-host only); bidirectional control (e.g., tare-on-command) requires optional StarCom™ Pro firmware upgrade and dedicated driver configuration.
What is the warranty coverage for this model?
OHAUS provides a 3-year limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory or industrial use conditions.
Are replacement batteries field-serviceable?
Yes—the Ni-MH battery pack is user-replaceable using a Torx T10 driver; OHAUS part number BATT-NIMH-TCS is available through authorized distributors.
