Hardness Tester: Accurate Material Hardness Analysis for Heat-Treated Metals

With a power output of 1 mW or less, Class 2 lasers can be used as precision laser leveling instruments which can project a horizontal or vertical line or even plumb dots and dots at an accuracy of ±0.3mm/m. Its self-leveling versions automatically adjust within a range of ±4° tilt. Cross-line lasers mark vertical and horizontal 90° crossings for tiling and aligning drywall installations along with machinery. Outdoor-grade lasers have a visibility of up to 30 m in daylight while having IP54 protection. Compared to traditional laser levels, outdoor-grade lasers enable collar mounted setups to be done 50% quicker. These lasers are crucial in woodworking and construction as well as industrial assembly.
