 cathetometer
 垂高計; 高差表; 高差計; 測高儀

From: Webster's Revised Unabridged Dictionary (1913)

 Cath·e·tom·e·ter n.  An instrument for the accurate measurement of small differences of height; esp. of the differences in the height of the upper surfaces of two columns of mercury or other fluid, or of the same column at different times. It consists of a telescopic leveling apparatus (d), which slides up or down a perpendicular metallic standard very finely graduated (bb). The telescope is raised or depressed in order to sight the objects or surfaces, and the differences in vertical height are thus shown on the graduated standard. [Written also kathetometer.]
