SOP TOP CON6300 Benchtop Conductivity Meter

Overview

The SOP TOP CON6300 Benchtop Conductivity Meter is a precision-engineered electrochemical instrument designed for routine and research-grade measurement of electrical conductivity, total dissolved solids (TDS), salinity, and resistivity in aqueous solutions. Operating on the principle of two- or four-electrode AC conductivity measurement—minimizing polarization effects and electrode fouling—the CON6300 delivers stable, reproducible readings across six decades of conductivity range (from ultra-pure water at 0.001 µS/cm to highly concentrated brines up to 500.0 mS/cm). Its modular cell constant support (0.01–10.0 cm⁻¹) enables accurate characterization of diverse sample matrices—from deionized water in semiconductor rinse baths to industrial process streams and seawater analogs—without recalibration. The meter incorporates dual-temperature sensing (°C/°F) with ±0.3 °C accuracy and configurable linear temperature compensation, ensuring traceable results aligned with ASTM D1125 and ISO 7888 standards for conductivity testing.

Key Features

• 5-inch multi-line LCD display with adjustable high-brightness backlight for optimal readability in lab and field environments
• Integrated rechargeable 3.7 V Li-ion battery base (battery not supplied) enabling uninterrupted operation during power interruptions or mobile deployment
• USB interface supporting direct connection to Windows-based PCs for real-time data streaming and firmware updates
• Onboard electrode health diagnostics—including conductivity drift trend analysis and cell constant validation alerts—to ensure measurement integrity prior to each assay
• Programmable auto-hold function with manual override, facilitating precise endpoint capture during titration or batch monitoring
• Configurable auto-power-off (default: 10 minutes idle) with optional disable setting for continuous logging applications
• Temperature offset calibration (±5.0 °C range) to correct for sensor thermal lag or immersion depth discrepancies
• Full parameter configurability: reference temperature (15.0–30.0 °C), temperature coefficient (0.00–9.99%), TDS conversion factor (0.40–1.00), and fixed salinity coefficient (0.65)

Sample Compatibility & Compliance

The CON6300 supports broad sample compatibility through interchangeable conductivity cells optimized for specific conductance regimes: low-conductivity cells (K = 0.01 cm⁻¹) for ultrapure water validation per ASTM D5127; standard cells (K = 0.1 or 1.0 cm⁻¹) for municipal drinking water (US EPA Method 120.1) and pharmaceutical water systems (USP ); and high-range cells (K = 10.0 cm⁻¹) for wastewater effluent and electroplating baths. All measurements comply with GLP documentation requirements via timestamped 100-point internal memory storage and exportable CSV logs. While the instrument itself does not carry FDA 21 CFR Part 11 certification, its data export architecture supports integration into validated LIMS or ELN platforms where electronic signatures and audit trails are managed at the system level.

Software & Data Management

Supplied with proprietary Windows-compatible data acquisition software (distributed on optical disc and downloadable from SOP TOP’s global support portal), the CON6300 enables synchronized time-series logging, customizable report generation (PDF/CSV), and overlay plotting of conductivity vs. temperature profiles. Software features include automatic unit conversion (µS/cm ↔ mS/cm ↔ ppt), batch ID tagging, and metadata annotation (operator, location, sample ID). Raw data files retain full resolution—including temperature-compensated values, raw sensor voltage, and diagnostic flags—ensuring full traceability for ISO/IEC 17025 accredited laboratories. No cloud dependency or subscription model is required; all processing occurs locally.

Applications

• Quality control of purified water in pharmaceutical manufacturing (WFI, PW) per USP and EP 2.2.38
• Monitoring reverse osmosis and EDI system performance in power plant boiler feedwater loops
• TDS estimation in agricultural irrigation water and hydroponic nutrient solutions
• Salinity profiling in marine biology and aquaculture research
• Electrolyte concentration verification in battery electrolyte R&D and fuel cell membrane hydration studies
• Environmental compliance testing of surface water, groundwater, and industrial discharge per ISO 10523 and APHA Standard Methods 2510B

FAQ

Does the CON6300 support GLP-compliant data recording?
Yes—each stored reading includes date/time stamp, measured parameters, temperature, cell constant, and operator-configured metadata. Exported files retain full precision and are compatible with third-party audit-trail systems.
Can I use non-SOP TOP conductivity cells with this meter?
The instrument accepts any DIN/ISO-standard conductivity cell with BNC or 6-pin connector and documented cell constant (0.01–10.0 cm⁻¹). Calibration verification is recommended before first use.
Is the USB interface capable of real-time data streaming?
Yes—software enables continuous acquisition at user-defined intervals (1–60 seconds), with live graphing and alarm-triggered logging.
What is the warranty coverage for the CON6300?
SOP TOP provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use.
How is temperature compensation applied during measurement?
The meter applies linear compensation using the formula: σ_T = σ_meas / [1 + α(T − T_ref)], where α is the configurable temperature coefficient and T_ref is the selected reference temperature.
