6 MODEL 225 CALIBRA TION CALIBRA TION The nominal cell constant of the Model 225 sensor is 2.7/cm. The error in the cell const ant is about ± 10%, so conductivity readings made using the nominal cell con- stant will have an error of at least ± 10%. W all effects, discussed below , will likely make the error greater .
