Spirit level Expert+ MN-70-508 80 cm — 90° and 0° vials, 2.3% slope, shock protection

The Expert+ MN-70-508 80 cm spirit level is a professional measuring tool designed for accurate horizontal, vertical and slight gradient checks. It features two integrated vials set at 0° and 90° and an additional graduation for a 2.3% slope, allowing precise alignment for a variety of construction and installation tasks. The aluminium profile provides a stable reference edge while external shock protection reduces risk of damage from drops and impacts during daily use.

Advantages

The aluminium body combines low weight with rigidity to maintain straightness over long use. Dual vials for 0° and 90° enable quick verification of horizontals and verticals, and the 2.3% slope graduation helps set small gradients without the need for additional instruments. Shock protection around the ends and along the profile increases durability on busy job sites and prolongs service life. Clear vial markings and robust mounting points support reliable measurements and easy handling.

Suitable for

• Plumbing work and pipe alignment
• Carpentry and door/window installation
• Tiling and floor leveling
• General construction and site layout tasks

Key specifications

• Length: 80 cm aluminium profile suitable for medium- to large-scale tasks
• Vials: two spirit vials for 0° (horizontal) and 90° (vertical)
• Slope graduation: 2.3% slope marking for small gradient settings
• Protection: external shock-protection elements at ends and along the frame
• Accuracy: professional-grade vial alignment for reliable measurement results

How to use

Place the spirit level on the surface to be measured, aligning the profile edge with the reference line or the object edge. For horizontal checks, read the central vial and adjust the workpiece until the bubble centers between the marks. For vertical checks use the 90° vial in the same way. To set a slight gradient, use the 2.3% slope graduation as a guide and adjust until the vial indicates the required incline. Handle the tool by its profile and avoid heavy impacts to maintain vial calibration.

Usage recommendations

Store the spirit level in a dry place away from extreme temperatures and impacts. Before critical measurements, verify vial calibration by measuring a known horizontal and vertical surface; if necessary, recalibrate or replace the tool. Clean the profile edge and vials regularly to ensure precise contact and clear reading.
