Eutech CyberScan COND 600 Portable Conductivity Meter

Overview

The Eutech CyberScan COND 600 is a field-deployable, high-fidelity portable conductivity meter engineered for rigorous electrochemical measurement in diverse aqueous environments—from ultrapure water in semiconductor rinse stations to high-salinity seawater and industrial process streams. It operates on the principle of two-electrode or four-electrode conductometric sensing, where electrical conductance is measured via alternating current (AC) excitation to minimize polarization effects and electrode fouling. The instrument automatically detects electrode cell constant (0.010–10.000 cm⁻¹) and dynamically selects among five predefined conductivity ranges (0–2.000 µS/cm up to 40.00–200.0 mS/cm), ensuring optimal signal-to-noise ratio across six decades of dynamic range. Its temperature-compensated conductivity calculation follows the linear temperature coefficient model referenced to user-selectable standard temperatures (15–30 °C), compliant with ASTM D1125 and ISO 7888 standards for conductivity reporting.

Key Features

• Auto-recognition of both 2-cell and 4-cell conductivity electrodes—enabling accurate low-conductivity (<1 µS/cm) ultrapure water measurements and high-conductivity (up to 500 mS/cm) saline or brine analysis without manual range switching
• Five auto-ranging conductivity spans with triple-level resolution: 0.01/0.1 µS/cm in µS mode; 0.001/0.01/0.1 mS/cm in mS mode—supporting trace-level monitoring and bulk salinity assessment within a single device
• Integrated temperature sensor (±0.5 °C accuracy) with selectable linear compensation (0–80 °C) and programmable TDS conversion factor (0.40–1.00), enabling compliance with USP , ASTM D5391, and ISO 5667-11 for TDS estimation
• IP67-rated enclosure—dust-tight and submersible to 1 m for 30 minutes—validated for outdoor, wastewater, and marine field use under adverse environmental conditions
• Backlit LCD display (5.4 × 7.1 cm) showing real-time conductivity, TDS, temperature, electrode constant, calibration status, and alarm thresholds simultaneously—no menu navigation required for primary readouts
• GLP-compliant data management with time-stamped, operator-ID-capable storage of 500 measurement records—including calibration history, electrode ID, date/time, and ambient temperature

Sample Compatibility & Compliance

The COND 600 is validated for direct immersion measurement in deionized water, potable water, cooling tower fluids, boiler feedwater, aquaculture systems, estuarine and coastal seawater, and food-grade processing rinses. Its dual-electrode architecture eliminates errors from cable capacitance and stray currents common in high-resistivity samples, while the optional four-ring electrode minimizes errors induced by electrode coating in turbid or particulate-laden matrices. The instrument meets IEC 61000-4 electromagnetic compatibility requirements and conforms to FDA 21 CFR Part 11 Annex 11 principles for audit-trail-enabled calibration records. All stored data include immutable timestamps and calibration metadata, satisfying GLP and GMP documentation expectations for QC laboratories and environmental monitoring programs.

Software & Data Management

Data export is supported via infrared (IrDA) and RS232C serial interface to PCs or LIMS platforms. The bundled Eutech LogEasy software enables batch download, graphical trend analysis, report generation (PDF/CSV), and automated validation of calibration drift against historical baselines. Each stored record includes full metrological context: measurement mode, electrode constant, temperature reading, compensation settings, and user-defined alarm limits. The system supports configurable auto-calibration reminders and alerts for expired electrode verification—critical for maintaining ISO/IEC 17025-compliant measurement uncertainty budgets.

Applications

• Pharmaceutical water system validation (PW, WFI) per USP and EU Annex 1
• Environmental field screening of surface water, groundwater, and effluent discharge compliance (EPA Method 120.1)
• Power plant cycle chemistry control—monitoring condensate purity and steam generator blowdown conductivity
• Aquaculture and hydroponics nutrient solution management
• Food & beverage sanitation rinse monitoring and CIP solution concentration verification
• Educational laboratory instruction in electrochemistry and water quality fundamentals

FAQ

Does the COND 600 support automatic temperature compensation for non-linear media such as concentrated brines?
No—it implements only linear temperature compensation (β-coefficient), consistent with ASTM D1125 and ISO 7888. For highly non-linear systems (e.g., >100 mS/cm NaCl), users must apply empirical correction tables or reference to IAPWS formulations externally.
Can the instrument store calibration data separately for multiple electrodes?
Yes—each calibration event is tagged with detected electrode constant and stored with full metadata, allowing traceability across interchangeable probes used in multi-site deployments.
Is the IrDA interface compatible with modern Windows/macOS systems without legacy serial ports?
Yes—via USB-to-IrDA adapters certified for HID-class infrared communication; drivers and configuration utilities are provided in the LogEasy installation package.
What is the recommended recalibration interval under continuous field use?
Per ISO/IEC 17025:2017 Clause 7.7.1, recalibration is advised before each critical measurement series or at 24-hour intervals when operating in variable-temperature or high-contamination environments.
Does the battery-powered operation meet ATEX or IECEx requirements for hazardous locations?
No—the COND 600 is not intrinsically safe certified; it is rated for general-purpose industrial and environmental use only.
