Overview
The Eutech Ion700 is a benchtop multi-parameter ion analyzer engineered for precise, routine measurement of ion concentration (via ion-selective electrodes), pH, oxidation-reduction potential (ORP), and temperature in laboratory and field-deployable environmental monitoring applications. Based on potentiometric detection principles, the instrument operates by measuring the voltage difference between an ion-selective electrode (ISE) and a reference electrode, converting the Nernstian response into quantitative ion activity or concentration (ppm or mol/L). Its architecture supports standardized electrochemical measurement protocols compliant with ASTM D1293 (pH of water), ASTM D3370 (sampling and analysis of ions in natural waters), and ISO 7888 (electrical conductivity and related parameters), making it suitable for regulatory-compliant water quality testing in municipal wastewater treatment, drinking water distribution systems, aquaculture, and industrial effluent monitoring.
Key Features
- Simultaneous measurement of pH, ORP, ion concentration (using interchangeable ISEs), and temperature — all within a single integrated platform
- Auto-buffer recognition for pH calibration across up to five points, supporting both USA and NIST standard buffer sets
- Multi-point ion calibration (2–5 points) with automatic slope calculation and offset verification per ISE
- GLP-compliant data handling: stores up to 100 measurement records with timestamp, electrode ID, calibration history, and measurement conditions
- Dual-line LCD display (5.6 × 7.5 cm) optimized for ambient-lit lab environments; large numeric characters ensure legibility during extended use
- Automatic or manual temperature compensation (0.0–100.0 °C) for pH and ion measurements, using either built-in ATC probe input or user-entered value
- Rugged, compact housing (17.5 × 15.5 × 6.9 cm; 650 g) designed for stable benchtop operation with integrated electrode stand
- Universal AC input (100–240 VAC, SMPS) ensures reliable power delivery across global laboratory infrastructures
Sample Compatibility & Compliance
The Ion700 interfaces with a broad range of commercially available ion-selective electrodes—including chloride (Cl⁻), nitrate (NO₃⁻), fluoride (F⁻), ammonium (NH₄⁺), sodium (Na⁺), potassium (K⁺), calcium (Ca²⁺), and cyanide (CN⁻) — enabling direct, non-destructive quantification in aqueous matrices without sample digestion. It accommodates standard BNC (for ISE/pH/ORP), phono (ATC), and phono (reference) inputs, ensuring compatibility with third-party electrodes meeting IUPAC-recommended impedance and junction specifications. The instrument conforms to IEC 61010-1 safety standards for electrical equipment used in measurement, control, and laboratory use. Data storage and calibration traceability support audit readiness under GLP and ISO/IEC 17025 frameworks, including documented electrode performance metrics (slope, offset, response time) required for method validation.
Software & Data Management
While the Ion700 operates as a standalone meter without proprietary PC software, its GLP-compliant internal memory logs each measurement with full contextual metadata: date/time stamp, measured parameter(s), electrode type, calibration status, temperature, and operator ID (manually entered). All stored entries are retrievable via front-panel navigation and can be manually transcribed or exported using optional RS232-to-USB adapters (not included). The system enforces data integrity through immutable record timestamps and prevents post-hoc editing—ensuring alignment with FDA 21 CFR Part 11 principles for electronic records where local IT infrastructure permits secure transfer workflows.
Applications
- Regulatory compliance testing of surface water, groundwater, and treated effluents per EPA Method 300.0 (anions) and Method 350.1 (ammonia)
- Process control in desalination plants (e.g., monitoring residual Cl⁻ post-chlorination or Na⁺ breakthrough in RO reject streams)
- Quality assurance in pharmaceutical water systems (PW, WFI) per USP conductivity and ion-specific verification
- Research-scale studies of ion exchange kinetics, nutrient leaching in soil lysimeters, and biofilm-mediated redox gradients
- Educational laboratories requiring robust, entry-level instrumentation for teaching electroanalytical fundamentals and ISE theory
FAQ
Does the Ion700 support direct molarity (mol/L) output for ions, or only ppm?
The instrument displays concentration in ppm by default; however, users may apply manual conversion factors (based on ion valence and atomic/molecular weight) during data interpretation. No built-in molarity mode is provided.
Can the Ion700 perform simultaneous dual-ion measurements (e.g., NO₃⁻ and Cl⁻) without electrode swapping?
No — like all single-channel potentiometric meters, the Ion700 requires physical electrode substitution between different ion measurements. It does not support multiplexed ISE arrays.
Is the 9V DC power supply included with the unit?
Yes — a regulated 9V DC adapter (100–240 VAC input, SMPS design) is supplied with each Ion700 unit.
What is the minimum detectable concentration for monovalent ions such as fluoride?
Detection limits depend on electrode performance and sample matrix; typical lower limits of quantitation (LLOQ) range from 0.02–0.1 ppm for high-quality F⁻ ISEs under controlled conditions.
Does the instrument provide diagnostic feedback for electrode degradation or junction clogging?
It displays real-time slope and offset values post-calibration, enabling users to assess electrode health against manufacturer-specified acceptance criteria (e.g., slope ≥ 54 mV/decade for monovalent ions).
