Beschreibung
Zusammenfassung:	The present invention relates to a measuring apparatus for growing length of a measuring object, and, specifically, to a measuring apparatus for growing length of a measuring object accommodated in a growth chamber, which comprises a long ascending/descending guide connected up and down, and arranged at the upper part of the growth chamber; a detecting unit having a predetermined length and a first magnet body on one side, and vertically arranged, and including a detecting probe ascending/descending within the ascending/descending guide; an ascending/descending unit surrounding a part of the external side of the ascending/descending guide, having a second magnet unit arranged to correspond to the first magnet unit, and selectively ascending/descending along the detecting probe along the ascending/descending guide by an external force; a measuring unit including a measuring part for measuring the moving distance by ascending/descending the ascending/descending unit; a position detecting sensor installed at the ascending/descending unit, and detecting one end of the detecting probe; and a detecting unit for controlling the operation of the ascending/descending unit according to the detection of the position detecting sensor.
