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.
