Spirit levels also known as bubble levels are invaluable for precision levelling measurement in a multitude of jobs, from something as simple as putting a shelf up to checking how level bricks are in a new wall. This hand held tool is easy to use and a simple way to maintain accuracy on the job. Spirit levels use a liquid filled vial with an air bubble inside. Guides on the vial indicate when the bubble is centred showing the user that it is level. Digital spirit levels also feature a digital readout for extra accuracy and assurance. For best results try to use the longest level that fits on the surface that is being checked on either the horizontal or vertical (plumb) planes.
An inclinometer sometimes known as clinometer is used for measuring the angles of slope or elevation, similar to a spirit level they can use various methods to measure and can be both analogue and digital read outs. Most commonly featuring a gravity-based pendulum others can use a spirit vial. Modern electronic inclinometers can be more precise with the digital measuring systems utilising gyroscopes and are becoming more popular than the classic spirit level due to higher requirements of precision, resolution, reliability, data storage and documenting.
RS Components offer a wide selection including block, box section, bulls eye, straight and torpedo levels.
A dual-vial system means that the two vials on the level work on whether it is lying on either its top or bottom edges.
