Ohaus Starter Conductivity Probes

Backed by our commitment to accurate and precise measurement, Ohaus Starter Conductivity Probes are designed to produce exact results time and time again.

The STCON3 utilizes the 4-ring potentiometric method for measuring conductivity, which incorporates a series of four stainless steel rings formed into the probe shaft. This design completely eliminates polarization, which occurs with the 2-plates amperometric method. Furthermore, without polarization the probe can measure a wider range of conductivity values because it does not suffer from electrolysis. The STCON3 conductivity probe has a built-in temperature sensor which is 30kΩ.

The newest conductivity probe to join the Starter Series is a 2-pole potentiometric probe, STCON7. STCON7 is especially designed for low conductivity measurements in mediums such as pure or distilled water. With a built-in 30KΩ temperature sensor, it performs automatic temperature compensation.
