Description

Ohaus STCON3 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 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 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.

  • Connection: Mini-Din
  • Cable Length: 1m
  • Shaft Length: 130 mm
  • Shaft Diameter: 14 mm
  • Temperature Range: 0-50 ˚C
  • Measurement Range: 70 µS/cm - 200mS/cm (0.5% accuracy) ; 2 μS/cm - 70μS/cm (1% to 5% accuracy)
  • Compatible With: ST300C portable meter

CARE AND USE

The STCON3 conductivity probe has a built-in temperature sensor which is 30kΩ.  When using STCON3, 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.
