| 摘要 |
The present invention relates to a horizontal level indicator assembly comprising: a measurement body which includes a first level indicator having a predetermined length; a second level indicator which penetrates both ends of the first level indicator, disposed to be inclined at a predetermined angle with respect to an imaginary line extending in a longitudinal direction of the measurement body, and is provided on one side of the measurement body; and a third level indicator disposed perpendicular to the imaginary line, and is provided on an other side of the measurement body wherein both ends of the measurement body including the second level indicator and the third level indicator can be extended and contracted to get farther away or closer with respect to the first level indicator, and the entire length of the measurement body is variable. Accordingly, vertical and horizontal degrees of a measurement target face having various areas and lengths can accurately and rapidly be measured by a single device. |
