conductivity sensor

This sensor is used in conjunction with a conductivity cell. It tends to used as a stand-alone meter to measure salinity or total dissolved solids in water. Offers some enhancement when used to monitor precipitation reactions on screen. 

Keep the conductivity cell as far as possible from the computer to minimise electrical noise that the cell can pick up. When transferring the cell from one solution to another, rinse in distilled water and shake rather than wipe to remove drops. After use wash in distilled water and store wet or dry. For absolute conductivity measurements, you may need to take account of the cell constant – a value may be marked on the cell.

These uses have been suggested:

  • acid-base titrations
  • precipitation and other titrations
  • measuring salinity of rock pools
  • environmental / water monitoring
  • conductimetric titrations.
