Metler Toledo TX-110ME Balance Data Printer

Overview

The Mettler Toledo TX-110ME Balance Data Printer is a dedicated, regulatory-compliant peripheral engineered for seamless integration with analytical and precision balances—including Mettler Toledo ME-series, AG-series, AL-series, and ZB-series instruments—as well as third-party balances from Sartorius, Shimadzu, Ohaus, A&D, and INTEK. Unlike generic label printers or PC-connected loggers, the TX-110ME operates as an autonomous, embedded data acquisition and reporting module that captures raw weight values directly from balance serial streams in real time. Its core architecture implements deterministic, low-latency communication protocols to ensure bit-level fidelity of transmitted mass readings—critical for audit-ready traceability under GLP, GMP, and ISO/IEC 17025 frameworks. The device employs an 8-pin impact dot-matrix print engine using standard plain paper and replaceable ribbons (Epson ERC-09/ERC-22), delivering archival-grade hard copies with >10-year legibility—fully compliant with FDA 21 CFR Part 11 requirements for non-erasable, non-modifiable printed records.

Key Features

• Regulatory-ready reporting: Built-in GLP/GMP header/footer templating with configurable fields—operator ID, instrument serial number, sample ID/batch number, timestamp (ISO 8601), sequence number, and digital signature line.
• Dual-mode printing: Configurable 24-character or 40-character line width; supports both impact (ribbon-based) and thermal printing modes for flexible media deployment.
• On-device statistical computation: Performs real-time calculation of mean, standard deviation, coefficient of variation, sum, min/max, and delta across up to 300 stored weighing entries using IEEE 754 double-precision arithmetic—no external software required.
• Pipette and volumetric glassware calibration mode: Implements JJG 646–2006 metrological procedures; automatically applies temperature-corrected volume conversion (K_t factor) to convert mass readings into equivalent volumes at 20 °C, supporting multi-point calibration with repeatability (S) and relative error (E) reporting.
• Multi-interface connectivity: Native RS-232 (default), optional USB 2.0 and RS-485 ports enable daisy-chaining in industrial scale networks or connection to legacy lab PCs without driver installation.
• 128×64 OLED display with bilingual UI: Supports English and Chinese language switching; provides real-time status feedback, parameter navigation, and local configuration without PC dependency.
• Data export capability: Integrated USB host port accepts standard FAT32-formatted USB flash drives for exporting CSV-formatted datasets directly to Excel-compatible spreadsheets—ideal for trend analysis and QA documentation.

Sample Compatibility & Compliance

The TX-110ME is validated for interoperability with over 120 models of laboratory and industrial balances, including but not limited to Mettler Toledo ME, AG, AL, ZB, and ICS platforms; Sartorius CPA, Q, P, and BS series; Shimadzu AUW, ATX, TX, and AP series; Ohaus Scout; A&D FX/iFX; and INTEK Midrics systems. It also interfaces with electrochemical instrumentation—including pH meters, ion analyzers, potentiometric titrators, and Karl Fischer moisture analyzers—from Mettler Toledo and Metrohm. All printed outputs comply with ISO/IEC 17025:2017 Clause 7.7 (results reporting), USP Analytical Instrument Qualification, and EU Annex 11 requirements for electronic records integrity. Audit trails include immutable timestamps, operator-assigned identifiers, and firmware-verified checksums on every printed page.

Software & Data Management

No proprietary software installation is required—the TX-110ME functions autonomously via hardware-level protocol parsing. Configuration is performed locally using the OLED menu system or remotely via ASCII command set (compatible with ANSI X3.4). All report templates are stored in non-volatile memory and survive power cycles. Header/footer elements—including facility name, department, instrument model, calibration due date, and QC reviewer signature block—are fully editable per SOP. Print logs retain metadata such as firmware version, last calibration timestamp, and interface handshake status—enabling full forensic reconstruction during regulatory inspections. Optional U-disk exports include .CSV files with column headers aligned to LIMS ingestion standards (e.g., “Sample_ID”, “Weighing_DateTime”, “Mass_g”, “Operator”, “Balance_Serial”).

Applications

• Pharmaceutical QC laboratories performing USP balance verification and weighing procedure validation.
• Chemical manufacturing sites requiring batch-record traceability per 21 CFR Part 211 Subpart J.
• Reference material producers documenting certified mass values under ISO Guide 34.
• Clinical trial labs executing Good Clinical Laboratory Practice (GCLP) compliant sample weighing.
• Academic research facilities maintaining FAIR (Findable, Accessible, Interoperable, Reusable) data principles through machine-readable printed archives.
• Calibration laboratories conducting pipette performance verification per ISO 8655-6 and volumetric flask certification per ISO 1042.

FAQ

Does the TX-110ME require drivers or software to operate with Mettler Toledo balances?
No—communication is handled natively via RS-232 ASCII protocol; no drivers, OS dependencies, or background services are needed.
Can the printer generate reports compliant with FDA 21 CFR Part 11?
Yes—printed outputs include permanent, non-erasable timestamps, operator identifiers, and unalterable record structure; electronic exports support digital signature embedding via external LIMS.
Is thermal printing supported out-of-the-box?
Thermal functionality is available as an optional configuration; standard units ship with impact printing enabled and ribbon pre-installed.
What is the maximum number of data points supported in statistical mode?
Up to 300 individual weighings can be stored and processed internally for statistical evaluation.
Does the device support barcode scanning integration?
Yes—via optional RS-232-connected barcode scanner; scanned IDs populate the Sample ID/Batch Number field automatically prior to printing.
