PURPOSE: A LED measurement probe for a near measurement target is provided to accurately display a measurement target with LED lights even in a dark space and to provide an accurate measurement target. CONSTITUTION: A LED measurement probe for a near measurement target comprises a measurement probe(100) and a variable measurement target unit(200). The variable measurement target unit(200) comprises a first variable mini measurement target, a second variable mini measurement target, a third variable mini measurement target, a fourth variable mini measurement target, a fifth variable mini measurement target, an insertion type water level meter, a screw thread unit, and a radial LED module. The first variable mini measurement target displays a first gradation displaying line being silk-printed on a surface of the first variable mini measurement target using LED lights of the radial LED module. The second variable mini measurement target displays a second graduation displaying line being silk-printed on a surface of the second variable mini measurement target using the LED lights emitted from the inside of the radial LED module by being upwardly projected after passing through the first variable mini measurement target. The third variable mini measurement target displays a third graduation displaying line being silk-printed on a surface of the third variable mini measurement target using the LED lights emitted from the inside of the radial LED module by being upwardly projected after passing through the second variable mini measurement target. The water level meter is inserted into the inside of a lower part surface of the first variable mini target and sets a reference balanced position of the measurement probe being joined to the lower part and the reference balanced positions of the first, second, third, fourth, and fifth variable mini measurement targets being joined to the measurement probe.
