Stabilas new 14 TECH level offers both a Stabila spirit level with patented vial system that are guaranteed accurate for life, and a dual display electronic level. The two digital displays are located on the top edge and the front face for easier and faster reads. The frame is 30% stronger than our previous electronic level and all four corners have been retained on the new frame. High accuracy electronic module 0.05 degrees (1/16 over 72) and offers fast and easy one-button calibration. Electronic module reads in degrees, percentage or inches per foot so you can set slope and pitch. Audible tone on any selected degree for duplicating angles quickly without having to read the screen. Great for concrete contractors installing handicap ramps or any sidewalk or slab that needs specific angle or slope. Inspectors use electronic levels to check contractors work. Trim carpenters use electronic levels to determine angles on stairs to build railings. Framing carpenters use electronic levels to check pitches on existing roofs and duplicate pitches on common rafters, difficult rafters or valleys and crickets. All professional contractors appreciate the speed of the Stabila TECH level to increase productivity and accuracy.
