Our servers are getting hit pretty hard right now. To continue shopping, enter the characters as they are shown These are handmade, do allow 0.4mm in diameter size fluctuation. We haven't found any with more than 0.35mm (at the max) variation though, in diameter. Sensitivity is used to indicate "the minimum volume of a gradient between a horizontal surface (or a vertical surface) forms with a level when a bubble of the level starts to move."

Archived from the original on July 10, 2009 . Retrieved 2009-07-29. Sensitivity is an important specification for a spirit level, as the device's accuracy depends on its sensitivity. The sensitivity of a level is given as the change of angle or gradient required to move the bubble by unit distance. If the bubble housing has graduated divisions, then the sensitivity is the angle or gradient change that moves the bubble by one of these divisions. 2mm (0.079in) is the usual spacing for graduations; on a surveyor's level, the bubble will move 2mm (0.079in) when the vial is tilted about 0.005 degree. For a precision machinist level with 2mm (0.079in) divisions, when the vial is tilted one division, the level will change 0.04mm (0.0016in) one meter from the pivot point, referred to by machinists as 5 tenths per foot. This terminology is unique to machinists and indicates a length of 5 tenths of 1 thousandth of an inch. [3] [4] Types [ edit ] Level tool being used to establish horizontality. Ebisu has created a marking system which classifies sensitivity, precision, and precision for use, so that users can properly understand the quality of Ebisu's products without any misreading. A traditional carpenter's spirit level looks like a short plank of wood and often has a wide body to ensure stability, and that the surface is being measured correctly. In the middle of the spirit level is a small window where the bubble and the tube is mounted. Two notches (or rings) designate where the bubble should be if the surface is level. Often an indicator for a 45 degree inclination is included.

Retrieved 2 August 2018. Ground spirit level vials are generally used in applications which require a higher degree of accuracy than is achievable with the lower cost plastic vials. We manufacture these in a wide range of sizes and sensitivities and produce many standard types as well as custom made products for OEM's. We have an advanced production facility which enables us to produce extremely high quality vials in small or large quantities at very competitive prices. Applications and Features A variant of the linear spirit level is the bull's eye level: a circular, flat-bottomed device with the liquid under a slightly convex glass face with a circle at the center. It serves to level a surface across a plane, while the tubular level only does so in the direction of the tube.

The history of the spirit level was discussed in brief in an 1887 article appearing in Scientific American. [1] Melchisédech Thévenot, a French scientist, invented the instrument some time before February 2, 1661. [ citation needed] This date can be established from Thevenot's correspondence with scientist Christiaan Huygens. Within a year of this date the inventor circulated details of his invention to others, including Robert Hooke in London and Vincenzo Viviani in Florence. [ citation needed] It is occasionally argued that these "bubble levels" did not come into widespread use until the beginning of the 18th century, the earliest surviving examples being from that time, but Adrien Auzout had recommended that the Académie Royale des Sciences take "levels of the Thevenot type" on its expedition to Madagascar in 1666. [ citation needed] It is very likely that these levels were in use in France and elsewhere long before the turn of the century.

These vials are incompletely filled with a liquid, usually a colored spirit or alcohol, leaving a bubble in the tube. They have a slight upward curve, so that the bubble naturally rests in the center, the highest point. At slight inclinations the bubble travels away from the marked center position. Where a spirit level must also be usable upside-down or on its side, the curved constant-diameter tube is replaced by an uncurved barrel-shaped tube with a slightly larger diameter in its middle.

Vials are stress-relieved, fast setting fluid-filled and precision bubble-sized as specified above. A similar procedure is applied to more sophisticated instruments such as a surveyor's optical level or a theodolite and is a matter of course each time the instrument is set up. In this latter case, the plane of rotation of the instrument is levelled, along with the spirit level. This is done in two horizontal perpendicular directions.A Selection of Stunning Leather multi-purpose storage pouches. For use with tools, accessories, pencil case, make up bag etc Adjustment of the spirit level is performed by successively rotating the level and moving the bubble tube within its housing to take up roughly half of the discrepancy, until the magnitude of the reading remains constant when the level is flipped.

A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical ( plumb).
