What is a Grade/Slope Laser Level?

A slope/grade laser lever is a measurement tool that is used in construction and surveying. Its laser beam indicator is fixed on a tripod that is leveled depending on the accuracy you desire to achieve.

This measurement tool will indicate a red or green beam when placed along the vertical or horizontal axis.

Types of Grade Lasers

There are 2 main types of grade lasers, dual slope grade lasers and single slope grade lasers. When using a single slope grade laser, you can get a reading on one axis on a slope at one go.

On the other hand, a dual slope laser offers you the opportunity to get a reading on two slopes while using separate axes simultaneously.

Grade Setting Methods

Grade lasers usually have two distinct grade setting methods; fully automatic and semi-automatic.

For example, the Leica Rugby 680 rotating laser is semi-automatic and is most suitable for different construction applications. Align, square, and level much quicker and eliminate downtime and costly errors.
