Introduction

In this introduction we tell you about the structure of spirit levels, their components and different models. This information is important for a do-it-yourself-man but especially for a seller of ironmonger’s.

Nowadays we live in the period of lasers and top electronics, but the good old spirit level is still the standard on construction sites. Spirit levels guarantee buildings the straightness of the walls and the right inclination of the floors. Many bangs are directed towards them, they get dirty of cement, they rattle on the platforms and are imposed to all kinds of stress. In spite of all these facts, spirit levels must always measure the right inclination carefully.

It doesn’t matter, if you use a small or a big spirit level, the operational principle of the spirit level is always the same. Traditional wood and state-of-the-art aluminium are the materials which rule on the market. Differences between different brands and manufacturing methods lie in details: the outer coverings and vials differ from manufacturer to manufacturer. There are also many spirit levels which are meant for special purposes of use like the long telescope spirit level for builders and magnet spirit level for metal workers.
