Level, characterized essentially by being constituted by a needle mounted swinging on a substantially horizontal axis, provided at one end with a counterweight that keeps the needle in vertical position, whose opposite end runs through an arbitrarily chosen circular scale, the needle-shaft assembly being arranged in a support provided with at least one flat base supported on the surface whose slope is to be measured, the reference of the scale and the slope of said base being related to the vertical position of the needle.
