Stanley Digital Angle Measuring Tool The 0-42-087 from Stanley is a professional digital angle level and is a great device for checking angles. This tool can take angle measurements from 0° to 180°. It features two vials, one horizontal and one vertical.

Inclinometers are used for measuring the angles of slopes or elevation and are similar to spirit levels. Electronic inclinometers can be more precise with digital measuring and are becoming more popular than the classic spirit level due to a higher requirement of precision, resolution and reliability.

Levels use a liquid filled vial with an air bubble inside to indicate how level or perpendicular a surface. Guides on the vial indicate when the bubble is centred showing the user that it is level. Features and Benefits: Backlit LCD screen

Length: 400mm Typical Applications: Spirit Levels and Inclinometers are tools designed for precision levelling measurement in a multitude of jobs, from something as simple as putting a shelf up making sure it does not slope, to checking how level bricks are in a new wall. They are commonly used by:
• Stonemasons
• Bricklayers
• Surveyors
• DIY Enthusiasts FAQs
Why so some levels have more than one vial?

One vial is used on horizontal level work and the other for vertical levelling work.
