An inclinometer is characterized wherein a thin, transparent plastic cylindrical container filled precisely one-half its volume by a inert liquid, is located in the middle of a homogeneous base in the shape of a quarter-circle whose two straight edges are exactly perpendicular, and when positioned upright, the surface of the liquid forms a longitudinal line intersecting the center of the cylinder and the first degree scale marked on the bottom of the cylinder; such that by viewing the said first scale opposite the liquid level, one can rapidly and directly measure the angle displaced by an object over a full 360-degree movement; or, for the purpose of finding any deviation from the horizontal plane, in any and all of the North, South, East and West directions, and/or any direction in-between each direction, can be measured by laying the inclinometer flat on the surface of the object whose inclination is to be measured, and the angular displacement is read directly from the second scale imprinted on the external wall of the cylinder.
