【Laser Level Function】- The digital spirit level tool can measure angles, check relative angles with zero calibration function and can also be used as a digital spirit level. The magnetic angle meter and two side lasers are great advantages for measuring, cutting, leveling when renovating wood and building furniture. It finds wide application in woodworking industry, plumbing industry, construction industry, machinery industry, automotive industry and DIY industry. Four-sided magnetic base: The digital inclinometer with powerful magnet on four sides can be attached to any ferrous metal surfaces such as pipes, steel structures, metal constructions and other ferromagnetic surfaces. Our angle gauge is a great helper and a good choice for angle measurement and adjustment. The 4 * 90 ° measurement can be used in many angles and will be adjusted to the same angle for comparison. 【Absolute and True Modes】 - The digital angle finder tool has two measurement modes - absolute and relative angle measurement (the absolute zero position of the digital angle finder has been calibrated at the factory); automatic shutdown - after 3 minutes without input or movement; automatic reversible display - when the meter is on the head; Hold button - freeze the current measurement value. Calibration function.
