Product Information

Here, you can also exercise your right of withdrawal (without the need to state any reason for doing so) by changing or fully withdrawing your voluntarily given consent with future effect. Alcohols have low viscosity and surface tension, which allows the bubble to travel the tube quickly and settle accurately with minimal interference from the glass surface. 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. This reading indicates to what extent the surface is parallel to the horizontal plane, according to the level, which at this stage is of unknown accuracy.

A. MOYER NAME HAS BECOME SYNONYMOUS WITH THE ULTIMATE IN QUALITY IN THE MANUFACTURE OF TUBULAR GLASS LEVEL VIALS.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.

Early tubular spirit levels had very slightly curved glass vials with constant inner diameter at each viewing point. 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.Starting from a point with a known elevation and going cross country (successive points being perhaps 100 meters (328ft) apart) height differences can be measured cumulatively over long distances and elevations can be calculated. citation needed] It is very likely that these levels were in use in France and elsewhere long before the turn of the century.

The level is placed on a flat and roughly level surface and the reading on the bubble tube is noted. Precision is defined to indicate "a reading of a certain measuring instrument or a comprehensive satisfactory performance including accuracy and precision (minimized dispersion in the values of measurement)" in the "Glossary of Measurement" of JISZ8103 (Japanese Industrial Standard).

The observer reads height values off two graduated vertical rods, one 'behind' and one 'in front', to obtain the height difference between the ground points on which the rods are resting. 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. They are used to level the foundations, or beds of machines to ensure the machine can output workpieces to the accuracy pre-built in the machine. Sensitivity is an important specification for a spirit level, as the device's accuracy depends on its sensitivity. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.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. 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. Seller has stated it will dispatch the item within 1 working day upon receipt of cleared payment - opens in a new window or tab .

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.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. 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.
