Overview
The Thermo Fisher Scientific Eutech COND600 Portable Conductivity Meter is a high-precision, field-deployable electrochemical instrument engineered for reliable measurement of conductivity, total dissolved solids (TDS), and temperature across an exceptionally broad dynamic range—from ultrapure water (down to 0.00 µS/cm) to concentrated seawater and brines (up to 200.0 mS/cm). Built upon dual-cell geometry recognition technology, the COND600 automatically detects and configures for either two-electrode or four-electrode conductivity sensors—enabling optimal accuracy in both low-conductivity (e.g., pharmaceutical water systems, power plant condensate) and high-conductivity (e.g., wastewater effluent, desalination intake) applications. Its measurement principle adheres to standardized AC conductometric methods per ASTM D1125 and ISO 7888, with automatic temperature compensation (ATC) based on linear β-coefficient algorithms (0–80 °C), referenced to user-selectable standard temperatures (15–30 °C). The device meets GLP (Good Laboratory Practice) requirements with full audit-trail capability for calibration events, electrode history, and measurement metadata.
Key Features
- Auto-sensing electrode interface: Recognizes 2- or 4-electrode cells and applies appropriate cell constant (0.010–10.000 cm⁻¹) without manual input
- Five auto-ranging conductivity spans: Seamlessly switches between 0–2.000 µS/cm, 2.000 µS/cm–300.0 µS/cm, 300.0 µS/cm–4.000 mS/cm, 4.000–40.00 mS/cm, and 40.00–200.0 mS/cm
- High-resolution display: Backlit LCD (5.4 × 7.1 cm) showing real-time conductivity/TDS/temperature, electrode constant, calibration status, and user-defined alarm limits
- Calibration flexibility: Supports up to 4-point automatic or 5-point manual conductivity calibration; configurable TDS conversion factor (0.40–1.00)
- Ruggedized design: IP67-rated enclosure ensures dust-tight and immersion-resistant operation (1 m for 30 min), suitable for outdoor, industrial, and wastewater field use
- Extended battery life: >200 hours of continuous operation on four AAA alkaline cells; optional 9 V regulated DC adapter support
Sample Compatibility & Compliance
The COND600 accommodates aqueous samples across diverse matrices—including deionized water, drinking water, boiler feedwater, cooling tower water, seawater, brackish groundwater, and process streams in food & beverage, pharmaceutical, and environmental monitoring labs. It complies with key regulatory frameworks: ASTM D1125 (Standard Test Method for Electrical Conductivity of Water), ISO 7888 (Water Quality — Determination of Electrical Conductivity), and USP (Electrical Conductivity of Water for Pharmaceutical Use). Its GLP-compliant data logging includes timestamped entries for calibration date/time, sensor ID, standard used, slope/offset values, and operator ID (via optional software integration). All stored data are traceable and exportable for FDA 21 CFR Part 11–aligned review workflows.
Software & Data Management
The meter stores up to 500 measurement records locally, each containing conductivity/TDS/temperature values, date/time stamp, electrode constant, and calibration reference points. Data export is supported via infrared (IrDA) or RS232C serial interface to PCs running Thermo Fisher’s Eutech PC Connect software—enabling CSV or Excel-compatible file generation, trend plotting, and report generation compliant with ISO/IEC 17025 documentation standards. Automatic calibration reminders and configurable auto-shutdown (2–30 min idle timeout) enhance operational consistency and energy efficiency. The “Auto-Lock” function freezes stable readings for documentation in variable-field conditions.
Applications
- Environmental monitoring: Surface water quality assessment, estuarine salinity profiling, and groundwater contamination screening
- Pharmaceutical manufacturing: USP compliance testing of Purified Water (PW) and Water for Injection (WFI)
- Power generation: Monitoring condensate purity and steam cycle chemistry control
- Food & beverage: Verification of rinse water conductivity in CIP validation and ingredient solution concentration
- Aquaculture & marine research: Real-time salinity (TDS) tracking in hatcheries and coral reef studies
- Academic teaching labs: Hands-on instruction in electrochemical principles, calibration theory, and water quality parameter interrelationships
FAQ
Does the COND600 support both 2-electrode and 4-electrode conductivity sensors?
Yes—it automatically identifies and configures for either sensor type, optimizing accuracy across low- and high-conductivity ranges.
What temperature compensation options are available?
Linear ATC (0–80 °C) with user-selectable reference temperature (15–30 °C); manual compensation is also supported.
Is the device compliant with FDA 21 CFR Part 11 requirements?
While the standalone meter does not provide electronic signatures, its data export structure and GLP logging features support integration into Part 11–compliant LIMS or ELN systems.
How many calibration points can be performed?
Up to 4 automatic or 5 manual calibration points across the full conductivity range.
What is the operating temperature range for field use?
0–50 °C ambient; storage range extends from –10 to 60 °C.
