Mitax- spirit levels are made of tube profiles.
The tube profiles are the strongest aluminium profiles but they are still not much heavier than the I-profiled. Another advantage: The tube profiled spirit levels have durable acrylic block vials. Most of Mitax spirit levels are tube profiled spirit levels. Profiles are manufactured in our factory by extruding it from aluminium bars. This manufacturing method guarantees a stronger stability then the older casting process. After this the surface of the profiles has been strengthened by anodising it electronically. Anodising gives the strong surface for our spirit levels.
Usually, the tube profiled spirit levels are complained about two things. Firstly, their middle vials are on the upper edge of the spirit level, which makes it difficult to draw a continuous line along the spirit level. Secondly, the end plugs make it difficult to draw a direct line to the corners. On the other hand, all of the spirit levels we have studied the aluminium tube profiled spirit levels are the most accurate spirit levels.
