The LE050 electronic level is composed by an alluminium structure with analogue display incorporated; wooden handle (in order to prevent influences on the structure with the manual contact); the internal mechanic of the pendulum is in an oil-bath box which protects against accidental shocks. A commutator permits the selection of one of the five possible resolutions (from 250 µm/m up to 1 µm/m) , while a potentiometer permits the "zero" setting. Rechargeable battery-powered, with battery status.
