WTW Cond 3310 Portable Conductivity Meter (2CA301 Cond 3310 SET 1)

Overview

The WTW Cond 3310 Portable Conductivity Meter (2CA301 Cond 3310 SET 1) is a rugged, field-deployable electrochemical analyzer engineered for high-reliability measurement of conductivity, resistivity, salinity, total dissolved solids (TDS), and temperature in aqueous media. Based on four-electrode (tetrapolar) AC conductivity measurement principle, the instrument eliminates polarization effects and electrode fouling artifacts—critical for stable readings in turbid, high-solids, or low-conductivity samples such as ultrapure water, wastewater effluents, or brine solutions. Its microprocessor-controlled architecture integrates automatic temperature compensation (ATC) with user-selectable reference temperatures (20 °C or 25 °C) and configurable compensation curves (linear, nonlinear, or none), ensuring traceable compliance with ISO 7888, ASTM D1125, and EN 27888 standards. Designed for both laboratory benchtop use and extended outdoor deployment, the Cond 3310 meets stringent environmental durability requirements without compromising metrological integrity.

Key Features

• Four-electrode conductivity measurement with TetraCon 325 sensor (included), minimizing polarization error and enabling accurate readings across wide dynamic range (0.000 µS/cm to 1000 mS/cm)
• Multi-parameter capability: simultaneous display and logging of conductivity, resistivity (0.00–20 MΩ·cm), salinity (0.0–70.0 ppt per IOT standard), TDS (0–199.9 g/L), and temperature (–5.0 to +105.0 °C, ±0.1 °C)
• Intelligent calibration management: 1–5-point calibration with auto-recognition of 16 DIN/NIST-certified buffer solutions; real-time electrode status feedback post-calibration
• Continuous Measurement Control (CMC): real-time validation of measurement validity—visual indicator when value falls within calibrated range; audible/visual alert if deviation exceeds defined thresholds
• Dual data storage architecture: 200 manually triggered entries + 5000 time-stamped automatic records (configurable interval: 1 s to 60 min), each storing parameter values, temperature, timestamp, sample ID, and calibration state
• IP66/IP67-rated housing with fully sealed silicone keypad and 100% waterproof USB interface for secure data transfer in wet or dusty conditions
• Energy-efficient design: up to 1000 hours of operation on standard AA batteries (backlight off); graphical LCD with adjustable backlight and auto-power-off (10 min–24 h)

Sample Compatibility & Compliance

The Cond 3310 accommodates diverse aqueous matrices including raw sewage, surface/groundwater, aquaculture systems, pharmaceutical process water, semiconductor rinse water, food & beverage formulations, and swimming pool sanitation streams. Its electrode constant adjustability (0.01–25.00 cm⁻¹) supports optimized configuration for ultra-low conductivity (e.g., deionized water with K = 0.01 cm⁻¹) or highly conductive brines (K = 10 or 25 cm⁻¹). The system complies with GLP documentation requirements through full audit trail functionality—including calibration history, operator ID (via optional PC software), and timestamped measurement logs. All firmware and calibration routines are validated against traceable NIST/DIN reference standards, supporting regulatory readiness for FDA 21 CFR Part 11 environments when paired with WTW’s LabX® Lite software.

Software & Data Management

Data export is enabled via the integrated waterproof USB port, compatible with Windows-based PCs and legacy handheld devices. Raw measurement files (.csv or .txt) retain full metadata (date/time, temperature, electrode ID, calibration status), facilitating integration into LIMS or statistical process control platforms. Optional WTW LabX® Lite software provides advanced reporting, trend analysis, and electronic signature support for GxP workflows. Firmware updates are delivered via USB and include version-locked calibration certificates, ensuring continuous metrological traceability. No cloud dependency or subscription model—data ownership remains fully under user control.

Applications

• Environmental monitoring: routine field assessment of river, lake, and groundwater conductivity for pollution tracking and regulatory reporting (EPA Method 120.1, ISO 7888)
• Wastewater treatment: real-time monitoring of influent/effluent conductivity to optimize coagulation, desalination, and membrane filtration processes
• Pharmaceutical manufacturing: verification of purified water (PW) and water-for-injection (WFI) conductivity per USP and EU Ph. Eur. 2.2.38
• Aquaculture & hydroponics: precise salinity and nutrient solution conductivity control to maintain species-specific osmotic balance
• Electronics industry: ultrapure water quality assurance in wafer cleaning lines where sub-µS/cm resolution is critical
• Food & beverage QC: batch consistency checks for brines, syrups, dairy processing water, and CIP rinse validation

FAQ

What electrode is included in the 2CA301 Cond 3310 SET 1?
The kit includes the TetraCon 325 four-pole conductivity sensor (K = 0.475 cm⁻¹), optimized for general-purpose field and lab use across 0.01–1000 mS/cm.
Does the Cond 3310 support GLP-compliant data handling?
Yes—when used with LabX® Lite software, it generates audit-trail-enabled reports with electronic signatures, calibration history, and user-defined metadata fields compliant with 21 CFR Part 11.
Can the instrument measure ultrapure water below 1 µS/cm?
Yes, using optional low-range electrodes (e.g., LF 92 with K = 0.01 cm⁻¹), the system achieves stable measurements down to 0.000 µS/cm with appropriate cell constant configuration.
Is automatic temperature compensation mandatory?
No—ATC can be disabled, and manual temperature input or fixed compensation coefficients (0.000–10.000 %/K) may be applied per application requirements.
How is calibration traceability maintained?
Each calibration event stores buffer IDs, measured values, deviations, and timestamps; calibration certificates from WTW-accredited labs are available upon request for IQ/OQ documentation.
