APPARATUS FOR MEASURING PH IN SOIL

摘要

Disclosed is an apparatus for measuring soil pH which can be used promptly at a site where crops are cultivated. The apparatus for measuring soil pH of the present invention includes a measurement module and a control display module. The measurement module includes a measurement module body part, a pH measurement part and a reference electrode part. The pH measurement part is arranged to be exposed from the measurement module body part, and measures a pH measurement potential value from a random soil and outputs the measured value. The reference electrode part is arranged in the measurement module body part, and generates a reference potential value and outputs the reference potential value. The control display module includes a control part and a display part. The control part receives the pH measurement potential value and the reference potential value from the pH measurement part and the reference electrode part respectively, and generates a pH measurement value as to the soil using a potential difference between the pH measurement potential value and the reference potential value. The display part is controlled by the control part and displays the pH measurement value to the outside. Thus, since the apparatus generates the pH measurement value through the potential value measured through the pH measurement part and then displays the pH measurement value through the display part promptly, a user can measure pH of the soil rapidly and easily, at the site where the crops are cultivated.
