precision tilt measurement: 4 x 90° measuring range with 0.2° accuracy enables quick and accurate angle readings for setup and verification. Flexible measurement modes: supports relative and absolute measurements interchangeably at any position; angle and slope readout conversion with a data hold function to freeze readings for transfer. Easy to read and power efficient: digital LCD display provides clear, intuitive readings; display auto off after 30 seconds of idle time and the device powers down after 3 minutes of idle time to conserve battery. Secure and portable design: builtin magnet allows the protractor to securely attach to metal surfaces for close fitting measurements; compact size, lightweight, and IP54 rated for dust and water splash resistance. Applications: Woodworking and carpentry: align miter saws, verify bevels and framing angles, set doors and cabinets with precise tolerances. Metalworking and fabrication: check weld joints, align fixtures, and verify machine base angles during setup. Construction and installation: ensure panel mounting, level surfaces, and tilt alignment of components in tight or limitedaccess areas.
