Abstract
A removable gelatinized calibration member is provided for use in storing or calibrating an ion concentration measuring device having measuring electrodes located in a concave measuring portion. The gelatinized calibration member is provided in the same shape as the concave measuring portion so that it may be removably placed onto the measuring device electrodes. The gelatinized calibration member may be a discrete pad or it may be provided in a rod-like configuration that can be moved in and out of a cylindrical housing.
