Ohaus STCON7 Conductivity Probe

The OHAUS Starter Series are designed to produce exact results time and time again.  They fit perfectly in holders on OHAUS bench meters as well as clips on all OHAUS portable meters. 

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.  The stainless steel measuring cell chamber can hold 316L.


  • Connection: Mini-Din
  • Cable Length: 1m
  • Shaft Length: 95 mm
  • Shaft Diameter: 12 mm
  • Temperature Range: 0-60 ˚C
  • Measurement Range: 02 μS/cm - 200μS/cm (accuracy: 0.02μS/cm)


When using STCON7, please consider the following:

  1. Make sure the plastic shield is in place when measuring.
  2. Be sure the solution reached the line on the plastic shield and below the vent hole when measuring.
  3. To prevent carry over from high to low conductivity solutions, rinse with distilled water between and after measurements.
  4. Make sure the cell chamber is bubble-free.
  5. Allow sufficient time for the sensor to stabilize when measuring samples at different temperatures. A manual end-point is advised.
  6. Do not expose the shaft to organic solvents when cleaning or when taking measurements.
  7. Do not use the probe outside the recommended temperature range.
  8. Calibrate the electrode with standard solution for an accurate measurement.
