OHAUS TCS-D51P15HR1 Precision Bench Scale

Overview

The OHAUS TCS-D51P15HR1 is a Class III precision bench scale engineered for reliable, repeatable mass measurement in regulated industrial, quality control, and light laboratory environments. Designed in accordance with OIML R76 international recommendations for non-automatic weighing instruments, it delivers certified accuracy at a verification scale interval (e) of 1 g across its full 15 kg capacity range. Its core architecture integrates a high-stability load cell system with digital signal processing optimized for low-drift performance under variable environmental conditions—critical for applications requiring traceable, auditable weight data. The scale’s modular design supports seamless integration into production lines, packaging stations, and QC workflows where compliance with GMP, GLP, and ISO/IEC 17025 documentation requirements is mandatory.

Key Features

• Class III accuracy certification per OIML R76, supporting regulatory compliance in pharmaceutical, food, and chemical manufacturing.
• 180° rotatable indicator housing enables flexible mounting—ideal for space-constrained workbenches or integrated conveyor setups.
• Backlit, wide-view LCD display ensures legibility under varying ambient lighting, including low-light production floors or controlled cleanroom environments.
• Dual-material construction: impact-resistant ABS polymer housing for the indicator unit and corrosion-resistant 304 stainless steel weighing pan for long-term durability and ease of decontamination.
• Multi-power architecture: compatible with AC mains power, factory-rechargeable Ni-MH battery pack, or standard AA alkaline cells—enabling uninterrupted operation during power outages or mobile deployment.
• Configurable unit system: supports SI units (kg, g), imperial equivalents (lb, oz), and up to three user-defined custom units—facilitating material-specific batch tracking or internal process metrics.

Sample Compatibility & Compliance

The TCS-D51P15HR1 accommodates a broad range of sample forms—including bulk solids, packaged goods, containers, and intermediate assemblies—within its 15 kg limit and 190 × 250 mm stainless steel pan surface. Its mechanical design meets IP42 ingress protection standards for resistance to dust and dripping water, making it suitable for humid or washdown-adjacent areas when used with appropriate safeguards. All weight data output via RS232 includes embedded timestamps and operator identifiers (when configured), satisfying ALCOA+ principles for attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available records. The scale supports audit-ready GMP/GLP data export protocols compliant with FDA 21 CFR Part 11 requirements when paired with validated software systems.

Software & Data Management

Standard RS232 serial communication provides ASCII-formatted weight data with configurable delimiters and optional metadata fields (date, time, mode identifier, unit code). When connected to host systems—such as LIMS, MES, or custom SCADA platforms—the scale transmits real-time measurements without proprietary drivers. Optional expansion modules enable simultaneous dual-port connectivity (e.g., primary RS232 to PC, secondary RS485 to PLC network) or discrete I/O control via AC/DC relay outputs for automated reject gates or fill-level triggers. Firmware updates are performed via USB-to-serial adapter, ensuring long-term maintainability and cybersecurity alignment with current NIST SP 800-53 controls for embedded devices.

Applications

• Checkweighing of prepackaged consumer goods against target weight tolerances per ISO 2859-1 sampling plans.
• Dynamic weighing of moving parts on slow-speed conveyors during final assembly verification.
• Inventory reconciliation via piece counting—leveraging auto-updating average piece weight (APW) calculation for mixed-batch lot management.
• Formulation support in compounding labs, where percentage-based ingredient addition must be tracked relative to a master batch reference.
• Raw material receipt inspection in food and nutraceutical facilities, aligned with SQF Code Edition 9 and BRCGS Issue 9 documentation expectations.
• Calibration verification logs for in-house metrology programs meeting ISO/IEC 17025 clause 6.5.2 requirements.

FAQ

What regulatory standards does the TCS-D51P15HR1 comply with?

It conforms to OIML R76 Class III accuracy requirements and supports GMP/GLP data integrity practices through timestamped, operator-identifiable RS232 output.
Can this scale be used in wet or washdown environments?

Its IP42 rating permits use in non-immersion environments with occasional splashing; however, direct high-pressure cleaning is not recommended without supplemental protective enclosures.
Is calibration certificate included with purchase?

A factory-issued calibration report traceable to NIST standards is provided; formal ISO/IEC 17025-accredited calibration requires third-party service engagement.
Does the scale support automatic tare function during continuous weighing?

Yes—tare can be applied manually or triggered automatically via programmable input (e.g., foot switch or relay signal) in checkweighing and dynamic modes.
How many custom units can be programmed?

Up to three user-defined units may be stored and recalled directly from the front panel interface without software assistance.
