The Conductivity Electrodes & Probes category includes the instruments, accessories and consumables needed to measure physical, chemical or mechanical properties and convert observations into data that can be compared, documented and acted upon. Selecting them as part of a complete workflow helps prevent compatibility problems that are easy to miss when individual items are considered separately.
Instrument suitability, calibration and sample preparation all influence whether a result is repeatable and meaningful. The practical choice therefore depends on measurement range, accuracy and resolution, sample type, and sensor or fixture compatibility, as well as how frequently the product will be used and how it connects with the rest of the procedure.
A sound measurement workflow links representative sampling, suitable sensors or fixtures, calibration or verification, controlled testing and reliable recording of results. When each stage is matched correctly, laboratories in research, quality assurance, manufacturing, environmental, education and service laboratories can work more consistently and manage changeovers, replenishment and maintenance with fewer interruptions. As part of the Analytical Measurement & Testing Equipment range, these products can be selected with the equipment and consumables used before and after this stage.
Our Conductivity Electrodes & Probes range
Our collection covers use these electrodes with any conductivity meter, integrated temperature measurement, benefits of a 4-electrode conductivity cell, and choosing the right cell constant for application, giving laboratories practical choices for routine work and more specialised applications.
Use these electrodes with any conductivity meter
While many sensors are compatible across brands, you must ensure the connector type (such as MiniDIN) and the temperature sensor type (Pt1000 or NTC) match your specific meter's requirements. The most suitable format depends on measurement range, accuracy and resolution, and sample type. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. Within the wider method, these products help laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. They should be reviewed together with associated consumables, accessories and cleaning requirements.
Integrated temperature measurement
Conductivity is highly temperature-dependent; probes with integrated sensors allow the meter to perform automatic temperature compensation, ensuring results are comparable at a standard reference temperature. The most suitable format depends on accuracy and resolution, sample type, and sensor or fixture compatibility. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. Used correctly, this part of the range helps laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. The result is a setup that is easier to train, document and maintain.
Benefits of a 4-electrode conductivity cell
Unlike 2-pole cells, 4-electrode cells like the WTW TetraCon 325 are largely immune to polarization effects and fouling, making them much more accurate for measurements in highly conductive or dirty samples. The most suitable format depends on sample type, sensor or fixture compatibility, and calibration requirements. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. Used correctly, this part of the range helps laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. The result is a setup that is easier to train, document and maintain.
Choosing the right cell constant for application
Probes with low cell constants are generally used for low-conductivity liquids like pure water, while higher cell constants are better suited for measuring concentrated chemicals or seawater. When comparing options, consider sensor or fixture compatibility, calibration requirements, and data handling. The correct choice should fit the sample, expected workload and any equipment already used in the method. Within the wider method, these products help laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. They should be reviewed together with associated consumables, accessories and cleaning requirements.
