Application Notes:
The Model CM is designed for use in seawater applications where the chloride level of the pore water is expected to remain nearly constant. It should be installed directly into the concrete as close as possible to the rebar where measurements are to be taken. Allow 60 days from the date of installation for the electrode to equilibrate to its surroundings. Subsequently, the Model CM will remain stable.
For those applications where the environmental conditions are expected to vary, or for concrete in fresh or brackish water, the Model CB-AGG should be used.
