The Klein Tools Digital Angle Gauge and Level can measure or set angles, check relative angles, or can be used as a digital level. The strong magnetic base attaches to ferromagnetic surfaces such as conduit. Along with dual measurement ranges of 0 to 90-Degree and 0 to 180-Degree, this tool has a high visibility reverse contrast display for easy viewing. Features: This Digital Angle Gauge and Level can measure or set angles, check relative angles, or can be used as a digital level; High visibility reverse contrast display improves visibility in dimly lit work environments; Strong magnetic base to attaches to conduit, pipes, saw blades, vents, ducts, and other ferromagnetic surfaces; V-groove edges enable optimal alignment on conduits and pipes for bending and alignment; 0 to 90-Degree and 0 to 180-Degree measurement ranges facilitate multiple and diverse applications; 0 to 180-Degree range is useful when accounting for kickback in pipe bending applications when bending to 90-Degree or more; Display auto-rotates when upside-down for easy viewing; Water and dust resistant with rating of IP42; Soft carrying case and two AAA batteries included; V-grooves Around Entire Perimeter, Dual Measurement Ranges at 0± to 90± and 0± to 180±, Reverse Contrast; This Digital Angle Gauge and Level can measure or set angles, check relative angles with zero calibration feature, or can be used as a digital level; 0 to 90-Degree and 0 to 180-Degree measurement ranges provide easy use in applications such as woodworking, bending conduit, installing electrical panels, and working on machinery; Digital Angle Gauge and Level can measure or set angles, check relative angles with zero calibration feature, or can be used as a digital level - Warnings: Read, understand, and follow instructions to ensure safe operation; Always wear approved eye protection; See instruction manual for additional warnings
