The Wadfow WLE1M03 15M Self-Leveling Line Laser is a compact and practical red-beam laser level designed to provide accurate horizontal and vertical reference lines for construction, installation and general alignment work. It offers a working range of 0–15 metres, making it suitable for indoor professional and DIY applications.
The laser provides levelling accuracy of ±2mm at 5m and line accuracy of ±2mm at 5m. Its self-levelling system automatically compensates for small positioning deviations within a ≤4° self-levelling angle, with a levelling time of ≤3 seconds.
The WLE1M03 produces both horizontal and vertical lines, allowing users to establish cross-line references for tasks such as tile alignment, cabinet installation, partition work, ceiling installation, carpentry, electrical installation and general construction layout. The integrated laser cross-lock function helps secure the laser during transportation or when manual positioning is required.
It uses a 635 ±5nm red laser classified as Class II, <1mW and is powered by two LR6 AA 1.5V batteries. The unit is specified for operation from 0°C to +40°C, with a storage temperature range of -10°C to +50°C.
