In an elevator for a water quality instrument having an elevator frame (7) provided on a post (5) so that it is able to ascend it, and a water quality instrument (3) supported via an arm (16) on the frame (7), the instrument (3) is able to rotate about a first rotational shaft which is along the longitudinal axis of the arm (16), and is able to rotate about a second rotational shaft which is along the elevational axis of the frame (7). The instrument (3) with this structure can be rotated from the vertical position to any horizontal position, and can also be rotated to any position about the rotational shaft along the elevational axis of the frame (7). Accordingly, the lift of the elevator can be reduced, and the instrument (3) can be checked and maintained at a safe position. |
