Horizontal Spirit Levels are used for inspecting and leveling horizontal surfaces and cylinders. Any level can be checked for accuracy on any flat surface regardless of whether it is level or not.  Simply put the level on the surface and note the position of the bubble.  Then reverse the level in the same spot.  If the level is true, the bubble will be in the same relative position both ways. Other Levels include Inspection Square Block Levels used for adjusting and checking horizontal and vertical surfaces. Cross Spirit Levels are used for leveling machines and other apparatus.
