Aluminium profile spirit level


High precision vial bubbles move 5x faster than those of ordinary levels. Therefore inaccuracies can be recognised much sooner- and much better. BMI-round bubble for glare-free effect. 0.3 mm / m mounting accuracy of vials in normal position. BMI 4-chamber profile, the most resistant profile in the market. Effective additional protection through shock-absorbing rubber end-caps.

Our Spirit Level glossary (PDF) provides a good comparison of the selected BMI Levels: The 690, 691, 692, 695, 698 and 699 and the 660, 661 and 665 models are listed here.
