Storage
Store the cell dry.

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 meas-
ured 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
Samples with high conductivities, sea wa-
ters, industrial process waters, bleaches
and concentrated acids, etc.
