Accuracy: (±)3mm, Wavelength: 670 nm
Filters
- Amateur / DIY: For home use, decoration, simple space measurements (with measurement accuracy over ±2.0 mm).
- Semi-professional: Satisfactory accuracy for project or workshop measurements (with measurement accuracy from ± 1.6 mm to ± 2.0 mm).
- Professional / Precision: Suitable for engineers, construction, surveying (with measurement accuracy up to ± 1.5 mm).
- Volume: It is used to calculate the volume of a space (e.g. room, warehouse, office)
- Surface: It is used to calculate the area (m²) of a flat surface, such as a wall, floor, ceiling, or window.
- Triangle: It is used to calculate areas or distances that form a triangle, not necessarily a right triangle.
- Pythagorean: Allows you to calculate a length (usually height or distance) that cannot be measured directly with the laser, by measuring two or three other distances that form a right triangle.
- Red: It is suitable for indoor work and short distances (wavelength: approximately 630 – 680 nm).
- Green: Offers excellent visibility, especially outdoors and over long distances (wavelength: approximately 515 – 550 nm).
- Measurement Accuracy: Measurement accuracy indicates how close the laser's result is to the actual distance.
- IP40: Protection against large dust particles, no resistance to water; suitable only for indoor, clean environments.
- IP54: Protection against dust and water spray from any direction; the most common rating for professional lasers for indoor and outdoor use.
- IP65: Complete protection against dust and low-pressure water jets; excellent for frequent outdoor use.
