pH Electrode Status
Electrode condition is good.
The electrode slope is in the range of 95.1% to 104.9 %.
Electrode condition is fair.
The electrode slope is in the range of 85.1% to 95.0% or in the range of 105.0 % to 114.9%.
Electrode condition is bad.
The electrode slope is less than 85% or the electrode slope is greater than 115%.
Consult the pH electrode user manual for instructions on how to clean, condition and
troubleshoot the electrode.
Note: This is a general indicator of overall electrode status – always refer to the pH electrode
user manual for specific information on the recommended slope range for each pH electrode.
