OHAUS TCS-D31XW30VR Waterproof Bench Scale

Overview

The OHAUS TCS-D31XW30VR is a rugged, IP67-rated waterproof bench scale engineered for reliable mass measurement in demanding industrial, food processing, logistics, and light manufacturing environments. Built on OHAUS’s legacy of precision weighing instrumentation, this model employs electromagnetic force restoration (EMFR) load cell technology to deliver high repeatability and long-term stability under variable ambient conditions—including exposure to moisture, dust, and routine washdown procedures. Its modular architecture separates the fully sealed, corrosion-resistant weighing platform from the independently rotatable indicator unit, enabling flexible installation in confined spaces or angled workstations. Designed for daily operational continuity, the TCS-D31XW30VR supports dual-power operation—rechargeable sealed lead-acid battery with up to 100 hours of standby time in auto-off mode, or continuous use via included AC adapter—ensuring uninterrupted functionality during shift transitions or facility-wide power fluctuations.

Key Features

• IP67-rated weighing platform and IP65-rated indicator housing—certified for resistance to high-pressure water jets and full submersion up to 1 meter for 30 minutes.
• 25 mm high-contrast backlit LCD display with intuitive 4-key membrane interface—optimized for gloved operation and rapid parameter navigation.
• 180° rotational indicator housing—enables vertical, horizontal, or tilted mounting without mechanical reconfiguration or hardware modification.
• Standard RS232 serial interface—supports direct connection to label printers, thermal receipt printers, PLCs, and host systems for real-time data logging and SPC integration.
• Three interchangeable platform configurations: 304 stainless steel (for hygiene-critical areas), chemical-resistant polypropylene (for corrosive environments), and impact-reinforced polymer (for high-drop industrial zones).
• Built-in battery management system with low-battery warning, automatic charging cutoff, and state-of-charge indicator—ensures consistent performance across extended duty cycles.

Sample Compatibility & Compliance

The TCS-D31XW30VR accommodates diverse sample types—from bulk food items and packaged goods to raw materials and intermediate components—without requiring recalibration between load categories. Its overload protection (150% capacity) and shock-absorbing foot design mitigate damage from accidental impacts or uneven loading. The scale meets NTEP Class III accuracy requirements (per Handbook 44) for commercial applications involving direct sales by weight, and carries CE marking under the EU Measuring Instruments Directive (MID 2014/32/EU). All firmware and calibration routines comply with ISO/IEC 17025 traceability protocols, and the device supports audit-ready calibration logs when paired with OHAUS SmartConnect software. While not FDA 21 CFR Part 11–validated out-of-the-box, its data export capabilities (CSV, TXT) and timestamped event logging enable seamless integration into GxP-aligned quality management systems.

Software & Data Management

The TCS-D31XW30VR operates autonomously but is fully compatible with OHAUS SmartConnect—a Windows-based configuration and data acquisition suite. SmartConnect enables remote setup of print templates (including barcodes, batch IDs, and tare offsets), user-defined application modes (e.g., parts counting, checkweighing, percent deviation), and automated export to Excel or LIMS databases. All communication follows ASCII protocol over RS232, ensuring interoperability with legacy MES and ERP platforms. Internal memory retains up to 999 transaction records with timestamps, operator IDs (via optional PIN login), and gross/net/tare values—facilitating root-cause analysis during nonconformance investigations. Firmware updates are performed via USB-to-RS232 bridge, with version rollback capability and checksum verification.

Applications

• Food & Beverage: Portion control, ingredient batching, and post-washdown verification in USDA-inspected facilities.
• Pharmaceutical Packaging: Secondary packaging line checkweighing where humidity and cleaning agents compromise conventional scales.
• Logistics & Warehousing: Pallet accumulation, parcel sorting, and returnable container reconciliation in damp dock environments.
• Chemical Distribution: Weighing of drums, IBCs, and intermediate bulk containers exposed to splashes or vapor condensation.
• Educational Labs: Introductory metrology training with emphasis on environmental resilience, uncertainty budgeting, and NIST-traceable calibration practices.

FAQ

What does the “W” in TCS-D31XW30VR signify?
The “W” denotes full waterproof certification—specifically IP67 for the platform and IP65 for the indicator—verified per IEC 60529 standards.
Can the scale be calibrated internally without external weights?
Yes—internal calibration is supported via built-in reference mass; external calibration using certified weights is required for NTEP or ISO/IEC 17025 compliance.
Is the battery replaceable by the end user?
The sealed lead-acid battery is field-replaceable using standard Torx tools; replacement kits include updated firmware patch and recalibration certificate.
Does the RS232 port support bi-directional communication?
Yes—both command-driven configuration (e.g., changing units or print format) and automatic data streaming (e.g., real-time weight output at 10 Hz) are supported.
Are platform options sold separately?
Yes—stainless steel (TCS-D31XW30VR-SS), polypropylene (TCS-D31XW30VR-PP), and reinforced polymer (TCS-D31XW30VR-RP) platforms are orderable as accessories with independent part numbers.
