Generally conductivity meters are available to measure cond of aqueous solution from less than 1 microS/cm to several mS/cm range. But for high conducting acid solutions (cond several S/cm) how can you proceed?
With response to Dr. Omar D Rodriguez the system as designed may not work. In this case where ionic conductivity is concerned one has to take care for polarization. Moreover the salinity scale is confined to sevaral mS/cm but what I need conductivity of solution which falls from 1S/cm to 100S/cm or still above. Hence for calibration some other alternatives have to be thought of.
