Abstract
A device for measuring ionic concentration in a sample liquid, having a detachable waterproof electrode housing. A body member has a computing device disposed therein and a display panel on an exterior surface. The waterproof electrode housing is demountably coupled to the body member. The electrode housing includes a flat surface sensor capable of measuring ionic concentration of the sample liquid when the device is placed on a flat surface, and is waterproof for measuring ionic concentration by immersion. A gap is formed between the body and the flat surface for preventing water from entering the body when the flat surface ionic concentration measurement procedure is being conducted.
