APPARATUS FOR SENSING SOLID MEDIUM PH USING NUTRICULTURE

摘要

The present invention relates to an apparatus for sensing solid medium PH using nutriculture. The apparatus comprises: a first electrode member electrically connected to a first electrode and a second electrode member electrically connected to a second electrode; a standard electrode unit which is electrically connected to a third electrode, include some metals and fluid that produce standard electromotive force by a chemical reaction between the metal and the fluid, and compare values of some electromotive force measured using the first electrode member and the second electrode member with the standard electromotive force value; an electrode body part on whose surface the first electrode member and the second electrode member are fixed; a signal processing unit electrically connected to the first electrode, the second electrode and the third electrode. When using the apparatus for sensing solid mediums, the PH of a solid medium can be sensed in real time, damage caused by impact can be reduced not by using glass electrodes and durability can be improved when a metal is used for an electrode unit.
