OHAUS STCON7 Low Conductivity Probe

The OHAUS STCON7 Conductivity Probe is a low-conductivity electrode designed for measuring samples such as pure water, distilled water, deionized water, and other low-conductivity laboratory solutions.

Unlike general-purpose conductivity probes intended for higher conductivity samples, the STCON7 is built for the low µS/cm range, with a measurement range of 0.02 to 200 µS/cm. It uses a 2-pole potentiometric measuring method and includes automatic temperature compensation through its built-in temperature sensor.

Why Choose the OHAUS STCON7?

• Low conductivity measurement range: Designed for 0.02 to 200 µS/cm conductivity measurements.
• Pure water application fit: Well suited for pure water, distilled water, and other low-conductivity sample types.
• 2-pole potentiometric design: Built for conductivity measurement in the low µS/cm range.
• Automatic temperature compensation: Built-in temperature sensor supports temperature-compensated conductivity measurements when used with compatible OHAUS meters.
• Mini-DIN connection: Designed for connection to compatible OHAUS Starter conductivity meters.
• 316L stainless steel measuring cell: Measuring cell chamber uses 316L stainless steel construction.
• Compact probe design: 95 mm shaft length and 12 mm shaft diameter for routine laboratory use.
• Canadian purchasing support: Supplied by Cambridge Environmental Products with CAD pricing and support for Canadian laboratories and facilities.

OHAUS STCON7 Specifications

Compatible Meter Notes

The STCON7 uses a Mini-DIN connection and is intended for use with compatible OHAUS Starter conductivity meters. OHAUS documentation identifies the STCON7 for use with the Starter 300C and Starter 3100C meters.

Before ordering, confirm that your meter accepts the STCON7 Mini-DIN conductivity electrode connection and supports the required low-conductivity measurement range for your application.

Care and Use Notes

For best results, rinse the probe with distilled water between measurements to reduce carry-over from one solution to another. When measuring, make sure the solution is above the cell chamber and that the cell chamber is free of bubbles.

Allow sufficient time for the probe to stabilize when measuring samples at different temperatures. If solids build up inside the cell chamber, carefully clean the chamber using a cotton swab soaked in detergent solution, then rinse the probe with distilled water.

Do not expose the probe shaft to organic solvents during cleaning or measurement. Do not use the probe outside the recommended temperature range. Follow the OHAUS meter manual and your internal laboratory procedure for calibration and measurement.
