Calibration Fluids for pH and EC Meters

Milwaukee Electrode Rinse Solution 20ml is ideal for rinsing your electrode between different calibration fluids, thus avoiding mixing them. This rinse solution is also ideal for removing any build-up on the probe or cap caused by evaporation of the storage solution. Although the build-up of this build-up is normal, it must be removed before measuring or calibrating !
