Level (spirit) Expert+ MN-70-515 — 150 cm, 90° and 0° vials, 2.3% slope, shock protection

Expert+ MN-70-515 is a 150 cm spirit level designed for professional and semi-professional alignment tasks in construction, installation and woodworking. The aluminium profile provides a straight reference edge while integrated vials indicate 0° (horizontal) and 90° (vertical) positions. An additional vial shows a 2.3% slope, enabling quick setting of slight gradients for drainage or fall. Built-in shock protection reduces the risk of damage from drops and impacts, extending service life on busy worksites.

Advantages

This 150 cm spirit level combines accurate bubble vials for horizontal and vertical orientation with a dedicated slope indicator, making it a versatile tool for alignment, leveling and slope setting. The robust profile and shock protection improve durability under typical site conditions, and the clear, easy-to-read vials speed up measurement tasks. The length balances reach and portability for tasks from tiling and carpentry to masonry.

Suitable for

• Aligning and leveling walls, floors and fixtures
• Setting a 2.3% fall for drainage on terraces, roofs or balconies
• Carpentry, cabinetry and joinery work requiring long straight edges
• Tiling and masonry where accurate vertical and horizontal checks are needed

Key specifications

• Length: 150 cm
• Vials: horizontal (0°) and vertical (90°)
• Slope indicator: 2.3% gradient vial
• Construction: aluminium profile with shock protection

How to use

Place the level against the surface to be checked or aligned, ensuring the profile sits flat along the reference edge. Read the bubble position in the horizontal or vertical vial to determine levelness or plumb; adjust the workpiece until the bubble centers. For slope setting, use the 2.3% vial as a reference and adjust supports or shims until the bubble aligns. Handle the tool by its profile and avoid striking the vials directly to maintain calibration.

Usage recommendations

Store the spirit level in a dry place and avoid prolonged exposure to extreme temperatures. Inspect vials regularly for cracks and verify accuracy against a known flat reference before critical measurements. Clean the profile and vial windows after use to ensure clear reading.
