Life of the cell
The cell lifespan is unlimited if suitable
maintenance is applied and the cell does
not break.
Troubleshooting
... Reading 0 independently of the mea-
sured sample.
Broken cable.
Replace the cell.
... Unstable reading.
... Impossible calibration.
Dirty measuring electrodes or air
bubbles on their surface.
Clean or shake slightly the cell.
... The obtained readings differ a lot from
the real values.
Verify that the conductivity is covered
by the measuring interval of the cell.
Re-calibrate using standards in good
conditions.
... slow cell response
Regenerate the cell.
Specifications
Applications
Clean waters, low conductivity waters,
