EUTECH CyberScan pH6500 Benchtop pH/ION/mV/ORP Meter

Overview

The EUTECH CyberScan pH6500 is a high-precision benchtop multi-parameter electrochemical analyzer engineered for rigorous laboratory, quality control, and research applications requiring trace-level pH, ion concentration, redox potential (ORP), and millivolt measurements. Built upon a robust dual-channel architecture, the instrument employs high-stability analog front-end circuitry and low-noise signal conditioning to deliver consistent, reproducible readings across extreme pH ranges (–2.000 to 20.000), enabling accurate characterization of highly acidic, alkaline, or non-aqueous samples—common in pharmaceutical formulation, semiconductor cleaning validation, and advanced materials synthesis. Its core measurement principle follows standardized potentiometric methodology per ASTM D1293 and ISO 10523, utilizing Nernst equation-based calculation with real-time temperature compensation to ensure thermodynamic fidelity. Designed and manufactured in the United States under stringent quality control protocols, the pH6500 complies with key regulatory frameworks including FDA 21 CFR Part 11 (when paired with validated software workflows), ISO/IEC 17025–aligned calibration traceability, and GLP documentation requirements.

Key Features

• Dual independent measurement channels support simultaneous, non-interfering acquisition of pH and ion concentration—or mV and ORP—enhancing throughput in multi-analyte workflows.
• Universal electrode interface accepts standard BNC pH glass electrodes and DIN-style ISFET sensors without adapters, reducing setup complexity and interfacial error sources.
• Five-point pH calibration with auto-buffer recognition across USA, NIST, and European standard buffer sets ensures rapid, operator-independent method setup and long-term drift monitoring.
• Comprehensive ion analysis mode supports direct concentration measurement, known-addition (standard addition), sample-addition, and subtraction methodologies—fully configurable for mono- and divalent ions per IUPAC-recommended protocols.
• Windows CE–driven 11.43 × 15.24 cm color touchscreen provides intuitive navigation, context-sensitive prompts, real-time electrode diagnostics, and on-screen slope/offset verification aligned with USP and EP 2.2.3 guidelines.
• Integrated GLP data management logs 1000 complete records—including date/time stamp, electrode serial number, calibration parameters, temperature, and user ID—with export via USB, SD card, or Ethernet to LIMS or ELN systems.

Sample Compatibility & Compliance

The pH6500 accommodates diverse sample matrices, including low-ionic-strength ultrapure water (with optional low-conductivity electrode), viscous industrial process streams, organic solvent mixtures (e.g., ethanol/water, acetonitrile), and high-salinity brines—provided appropriate electrode selection and junction design are applied. All measurements adhere to internationally recognized electrochemical standards: pH accuracy is verified against NIST-traceable reference solutions; ion quantification follows ISO 14911 for ion-selective electrode performance; and temperature compensation conforms to the ITS-90 scale. The instrument’s hardware and firmware architecture supports audit-ready GLP compliance, including electronic signature capability (via external authentication), immutable calibration logs, and full traceability of measurement conditions—critical for laboratories operating under ISO 9001, ISO 13485, or GMP environments.

Software & Data Management

Data integrity is maintained through built-in timestamped storage of all measurements, calibration events, and system diagnostics. The pH6500 exports CSV-formatted datasets compatible with Microsoft Excel, LabArchives, and industry-standard LIMS platforms. USB and RS232C ports enable bidirectional communication with PC-based EUTECH LogPro software for advanced trend analysis, report generation (PDF/Excel), and automated compliance reporting. Optional Ethernet (RJ45) connectivity allows remote monitoring and integration into centralized lab networks. All stored data includes electrode identification, slope (%), offset (mV), temperature, and environmental metadata—satisfying 21 CFR Part 11 requirements when deployed with validated software and access controls.

Applications

• Pharmaceutical QC: pH and ion profiling of injectables, buffers, and lyophilized formulations per USP and EP 2.2.3.
• Environmental Monitoring: Field-deployable lab verification of wastewater alkalinity, heavy metal ion concentrations (e.g., Pb²⁺, Cd²⁺), and redox status in remediation sites.
• Academic Research: Electrochemical characterization of novel electrolytes, battery slurries, and enzyme-catalyzed reactions requiring sub-millivolt stability.
• Food & Beverage: Titration endpoint verification, acidulant concentration control, and shelf-life stability testing under variable temperature regimes.
• Chemical Manufacturing: In-process monitoring of caustic scrubber solutions, catalyst activation baths, and polymerization reaction pH windows.

FAQ

Does the pH6500 support automatic temperature compensation during ion measurements?
Yes—ATC is fully integrated for both pH and ion modes, using either built-in or external Pt1000 temperature probes calibrated to ITS-90.
Can the instrument store calibration data for multiple electrodes separately?
Yes—each electrode can be assigned a unique ID; calibration history, slope, offset, and usage logs are stored per electrode identifier.
Is the touchscreen interface operable with gloves or in humid laboratory environments?
The resistive color touchscreen is rated for operation at up to 85% relative humidity and responds reliably to gloved fingertips or stylus input.
What regulatory standards does the pH6500 meet for pharmaceutical use?
It supports GLP/GMP workflows and, when used with validated procedures and EUTECH LogPro, satisfies data integrity requirements of 21 CFR Part 11, Annex 11, and EU GMP Chapter 4.
How is measurement uncertainty documented for audit purposes?
Each stored reading includes calculated expanded uncertainty (k=2) based on electrode specifications, calibration residuals, temperature drift coefficients, and resolution limits—exportable in audit-ready format.
