Abstract

The present invention provides a level (20) comprising a housing (21) that is set on a surface to determine its inclination. An oblate spheroid vial (22) is disposed within the housing and contains a liquid and inclination indicating means (23) to indicate the inclination of the surface. The indicating means may comprise an air bubble formed in the liquid or a float. The vial may have opposed raised hemispheroid surfaces (30, 31) and a curved equatorial periphery and positional markings may be provided on the vial. The housing may be located on a surface in at least two orientations, and can provide differing levels of accuracy in each.
