This compact model has a cast aluminium profile with a bevelled shape, making it one of STABILA's most robust spirit levels. With this model, you always have your hands free when aligning and adjusting construction elements on metal surfaces. The 81 SM Torpedo is equipped with a rare-earth magnet system that offers optimum adhesion. The vial and the milled measuring surface are precisely aligned during the manufacturing process and then permanently bonded together. In this way, STABILA ensures that the spirit level continues to measure absolutely accurately even after years of use.
The extra-strong adhesion of the rare-earth magnets is particularly useful in metal and scaffolding construction, as well as in assembly and welding work.
