Before ordering, confirm that your meter accepts the STCON3 electrode connection and supports the conductivity range required for your application.

STCON3 vs STCON7 Selection Note

The OHAUS STCON3 is the better fit for broad-range conductivity testing, including many routine water, wastewater, environmental, food, beverage, and QC samples.

If your application is focused on very low-conductivity samples such as pure water, distilled water, or deionized water, the OHAUS STCON7 Low Conductivity Probe may be a better choice. Contact Cambridge before ordering if you are unsure which OHAUS conductivity probe is correct for your sample range.

Care and Use Notes

For best results, keep the plastic shield in place during measurement and make sure the solution reaches the correct level on the shield while remaining below the vent hole.

Rinse the probe with distilled water between and after measurements to reduce carry-over, especially when moving from high-conductivity samples to lower-conductivity samples.

Make sure the cell chamber is bubble-free during measurement. Allow sufficient time for the sensor to stabilize when measuring samples at different temperatures. Follow the OHAUS meter manual and your internal laboratory procedure for calibration, measurement, cleaning, and storage.

Common Questions About the OHAUS STCON3 Conductivity Electrode

What is the OHAUS STCON3 used for?

The OHAUS STCON3 is used for broad-range conductivity measurement in water, wastewater, environmental, food and beverage, brewing, education, research, and quality control applications.

What is the measurement range of the STCON3?

The STCON3 measurement range is 2 µS/cm to 200 mS/cm.

Is the STCON3 a 4-ring conductivity electrode?

Yes. The STCON3 is a 4-ring conductivity electrode designed for broad-range conductivity measurement.

Does the STCON3 include temperature compensation?

Yes. The STCON3 includes automatic temperature compensation when used with a compatible OHAUS meter.

Which meters are compatible with the STCON3?

OHAUS lists the STCON3 as applicable for ST300C, ST400M, AB23EC, AB33EC, and AB33M1 meters. Confirm compatibility before ordering if you are using another OHAUS meter.

Is the STCON3 suitable for wastewater testing?

Yes, the STCON3 can be suitable for many routine wastewater and environmental conductivity testing workflows, provided the expected conductivity range and meter setup match the application.

Is the STCON3 suitable for pure water testing?

The STCON3 can measure down to 2 µS/cm, but for very low-conductivity pure water, distilled water, or deionized water testing, the OHAUS STCON7 may be a better fit.

How should I clean the STCON3?

Rinse the probe with distilled water between and after measurements. Make sure the cell chamber is free of bubbles and follow the OHAUS meter manual and internal laboratory procedure for cleaning and storage.
