Laser levels can be classified according to laser color, functional complexity, and operating environment. Based on laser color, they can be divided into red-beam and green-beam laser levels. Based on functional complexity, they can be categorized into basic models, multi-line models, models with plumb-down point functionality, and 360° omnidirectional models. Based on the operating environment, they can be classified as indoor-only models or dual-use indoor/outdoor models.
The HAD-APL305, DP-APL305, and XRS-APL305 series are self-leveling laser line projectors. Utilizing semiconductor lasers with a wavelength of 635 nm, these devices generate multiple mutually orthogonal vertical and horizontal lines; they feature a plumb-down point function, offer 360° rotation capabilities, are suitable for both indoor and outdoor use, and boast a horizontal accuracy of ±1 mm/10 m. The Ruipin 502 laser line projector features a laser wavelength of 635 nm, a self-leveling range of ±3°, and a horizontal accuracy of ±1 mm at a distance of 5 meters. The Bosch GTL 3 red-beam laser level projects three laser lines, offers a horizontal accuracy of ±0.2 mm/m, utilizes a laser wavelength of 635 nm, and is designed for indoor use.
The Fluke PLS 6R red-beam laser level features a laser wavelength of 635 nm, is designed for outdoor use, and includes a self-leveling function. The Huashengchang (CEM) LM-02T supports the projection of both horizontal and vertical lines. The Huashengchang (CEM) LM-16T features multi-line projection capabilities, providing comprehensive 360° alignment coverage. The PRO GCL 2-50 CG Professional combination laser level projects green laser lines, utilizes laser diodes with a wavelength of 500–540 nm, offers an accuracy of ±0.3 mm/m, features a self-leveling range of ±4°, and holds an IP54 rating for dust and splash protection.
