Calibrate a conductivity sensor

Improve the accuracy of a conductivity sensor, such as the Wireless Conductivity Sensor (PS-3210A), via calibration.

Before you start

Calibrating a conductivity sensor will require the following supplies:

• Two beakers
• Two standard solutions of known conductivity
• De-ionized water

Calibration

1. Connect your conductivity sensor to Capstone.
2. Select Calibration from the Tools palette.
3. Select Conductivity from the dropdown box, then click Next.

4. Ensure that Two Standards (2 point) is selected from the list of calibration types, then click Next.

   

5. Insert the conductivity sensor's probe into a beaker containing your first standard solution, making sure the sensing element is immersed. Wait for the value of conductivity recorded in the Current Value box to stabilize.

6. Enter the known conductivity of the first standard solution into the Standard Value box, then click Set Current Value to Standard Value.
7. Remove the sensor from the first beaker and rinse the probe with de-ionized water.
8. Insert the probe into a beaker containing the second standard solution, making sure the sensing element is immersed. Wait for the value of conductivity recorded in the Current Value box to stabilize.

9. Enter the known conductivity of the second standard solution into the Standard Value box, then click Set Current Value to Standard Value.

   

10. Review your new calibration to ensure it is appropriate, then click Finish.
