Includes a data hold function and provides angle and slope readout conversion for convenient measurement capture and flexible readings. IP54 dustproof protection offers dependable durability in dusty environments; the digital level has a long service life, helping reduce replacement costs. Use scenarios Construction framing and wall alignment: quickly verify verticality and level across studs or frames by switching between relative and absolute measurements as you move along. Carpentry and cabinetry installation: check and transfer angles and slopes for accurate mounting of cabinets, countertops, or trim, using the data hold function to capture measurements while repositioning. Roofs and stairs planning: assess angles and slopes on uneven surfaces, and use the angleslope conversion to determine the correct pitch for components.
