6 MODEL 225 CALIBRATION CALIBRATION The nominal cell constant of the Model 225 sensor is2.7/cm. The error in the cell constant is about ± 10%, so conductivity readings made using the nominal cell con-stant will have an error of at least ± 10%. Wall effects, discussed below, will likely make the erro...
