When was the first spirit level made?
1661
The spirit, or bubble, level, a sealed glass tube containing alcohol and an air bubble, was invented in 1661.
Where did the spirit level come from?
To find a more modern tool we need to travel to 1661 when the French scientist Melchisedech Thévenot invented the modern spirit level. Although, it took til the beginning of the 18th century before the invention spread.
Why is a spirit level so called?
A Spirit Level is a tool used to indicate how parallel (level) or perpendicular (plumb) a surface is relative to the earth. A spirit level gets its name from the mineral spirit solution inside the levels.
Who make the best spirit levels?
Top brands of spirit level include Stabila and Stanley. They are renowned for their quality and precision. Stabila spirit levels are available in a variety of different lengths and styles. One of our favourites is the 96-2 range.
Does the iPhone have a spirit level?
Yes, your iPhone has a built-in function that can work out if a surface is level, so you can do away with your giant, clunky spirit level. In fact, it’s in the Measure app, which is one of the default apps that comes pre-installed on all Apple iPhones.
Does clinometer have spirit level?
Explanation: Clinometer: It is an instrument for measuring angles of slope, elevation or depression of an object with respect to the ground. A clinometer is a special case of a spirit level.
Why was the spirit level invented?
Used to ascertain whether a surface is level on a horizontal surface or plumb, or for vertical accuracy, the history of the spirit level is thought to date back as far as the early 15th Century. The spirit level was invented by Melchisedech Thevenot.
How is a spirit level made?
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.
How accurate are stabila levels?
STABILA provides this level of accuracy by the use of precision machining and multi-stage testing in the manufacturing process. The accuracy of all aluminium spirit levels is 0.5 mm/m in the normal position. Models which are suitable for reverse measurement offer an accuracy of 0.029°, 0.043° or 0.057°.
Is a longer level more accurate?
Two things to keep in mind: the longer the level, the greater the accuracy — and that when working in cramped quarters, an overlong level is useless. So having a nine-inch torpedo level in your kit is probably a good idea. There are smaller one, too, as short as an inch in length.
Does iPhone 12 have a level?
Apple’s latest operating system, iOS 12, introduced the augmented-reality Measure app. All you need to do to find the level is open the Measure app!
Does iPhone 7 have a level?
Conveniently, iOS 7 and later has included one, though it’s not clearly apparent how to access it. The bubble (also known as spirit) level is not a stand alone app, rather it is accessed via the Measure app: 1. Open up the Measure app.
Who was the inventor of the bubble level?
History of the Bubble or Spirit Level. Thevenot invented the instrument some time before February 2, 1661. This date can be very accurately 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…
When was the level invented?
In the 1920s, Henry Ziemann the founder of Empire Level, invented the modern level with a single vial.
How is the adjustment of the spirit level done?
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.
How many degrees does the spirit level go through?
The spirit level is then rotated through 180 degrees in the horizontal plane, and another reading is noted. If the level is accurate, it will indicate the same orientation with respect to the horizontal plane.
