Magnetic Bubble Level is a tool used to determine whether a surface is horizontally level or vertically plumb. It consists of a sealed vial containing a liquid and an air bubble. The position of the bubble within the vial indicates the levelness of the surface upon which the tool rests.
What distinguishes a magnetic bubble level from other types of bubble levels is its magnetic base. This allows the level to be attached securely to ferromagnetic surfaces (like iron or steel) without the need for hands or other supports. This feature is particularly handy in situations where the user needs to work hands-free or when working with metal surfaces.
Magnetic bubble levels are commonly used in construction, carpentry, and many other professions where ensuring a level or plumb surface is essential. They can also be found in household toolkits for hanging pictures, installing appliances, and other DIY projects.
Common Types
Magnetic bubble levels come in various types based on design, intended use, and specific features.
- Torpedo Level: Compact and typically less than a foot in length, this type is equipped with multiple vials to measure different angles. It’s great for tight spaces and small tasks.
- I-Beam Level: Shaped like the letter “I”, it is often used for larger jobs and offers greater accuracy over longer lengths.
- Box Beam Level: Rectangular in shape, these are typically more durable and resistant to bending.
- Post Level: Designed to wrap around two sides of a post or pipe to check for level in two planes simultaneously.
- Cross Check Level: Small, often used in RVs or for photography, to ensure level in two planes simultaneously.
- Pocket Level: As the name suggests, these are small enough to fit in a pocket, often with a clip, and are handy for quick checks.
- Line Level: Designed to hang from a string, useful for leveling across longer distances, such as when setting the grade for landscaping or masonry.
- Electronic/Digital Levels: Provide digital readings and often come with backlit screens for better visibility. Some models can offer audio indications when a surface is level.
- Surface Level: Small, typically round or square, designed to rest flat on a surface to check if it’s level.
- Specialty Levels: These are designed for specific tasks, such as scaffolding levels with a groove to sit on a pipe or a fence post level.
When considering a magnetic version of these types, the primary feature is the inclusion of magnets, usually on the base or edge, which allows the level to adhere to metal surfaces without slipping. This is especially useful when working alone or in tight spaces.
