PROBLEM TO BE SOLVED: To solve the problem wherein reading errors in visual observation, since the air bubble of a single transparent container level pipe which detects the horizontal level from the location relation of a reticle and the air bubble is a very small moving amount. SOLUTION: The inside of a cylindrical transparent container is divided by a transparent partition plate into two chambers. The upper part of the inside surface of each divided room is curved and turns convex upward in an arc shape. The upper convex curved surface of the upper part of each divided chamber inside consists of mutually different curved ratio (curvature). A fluid is filled in and sealed so that an air bubble is made to exist in each of the inside of the two chambers of the transparent container. According to this constitution, the problem is solved by the two-chamber transparent container level pipe characterized by comprising the two-chamber transparent container.
