What is Spirit Level? A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Different types of spirit levels may be used by carpenters, stonemasons, bricklayers, other building trades workers, surveyors, millwrights, and other metalworkers, and in some photographic or video graphic work. 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. The best spirit level is accurate to within plus or minus 0.5 millimeters/meter, or 0.005 inches/inch or 0.029 degrees. Typically, the vials in a spirit level are a yellowish-green color with additives for UV protection and maximum performance in temperatures ranging from -20 degrees F to 130 degrees F. The next level of accuracy displayed is 0.75mm/m or.043 degrees. The vial bodies of a spirit level, also referred to as a bubble level, can be shaped like a barrel, like a rectangular block, or even curved, banana-shaped, to measure slope infractions per foot of pitch; and are mostly made from acrylic today versus glass originally. Construction Early tubular spirit levels had very slightly curved glass vials with a constant inner diameter at each viewing point. These vials are incompletely filled with a liquid, usually a colored spirit or alcohol, leaving a bubble in the tube. They have a slight u...

The level is placed on a flat and roughly level surface and the reading on the bubble tube is noted. 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. 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. A difference implies that the level is inaccurate. Adjustment of the spirit level is performed by successively rotating the level and m...

Finding the best spirit levels can be perplexing, especially if you’re a beginner. There are a lot of entries that aren’t very differentiated, so where do you start? What’s the difference between an $8 level and a $108 level? As a former carpenter and cabinet installer, I’ve literally used spirit levels every day of my life for years on end. It’s true, the difference between a good one and a bad one can have a lot to do with personal preference. But at the end of the day, every spirit level needs to have one central quality: accuracy. Check our product guide for help finding the right level for your situation. The Craftsman Box Torpedo level was a trusty standby, as tested. It has a stout profile that still fits in my During the review period, I was most happy with the level’s durability. Sometimes, a drop destroys a level — I’ve seen it happen before. But the Craftsman Box Torpedo didn’t budge after several drops on a hardwood floor from overhead height. I did have to drop test it as part of my due diligence, but I would have hated to see the level go. It worked in my tool bag, and it was handy for quick jobs around the house — shimming a cabinet and plumbing my refrigerator. All things considered, I’d recommend the Craftsman Box Torpedo level to anyone who wants a solid 9-inch level built to last. It did everything I wanted it to, and its magnified vials were easy to read. Overall, I was happy with it except for the minor criticism of being a little thick for its length....

The eye-opening and headline-generating UK bestseller that shows how one single factor the gap between its richest and poorest members can determine the health and well-being of a society. "This is a book with a big idea, big enough to change political thinking...In half a page [ The Spirit Level] tells you more about the pain of inequality than any play or novel could." Sunday Times (UK ) It is well established that in rich societies the poor have shorter lives and suffer more from almost every social problem. Now a groundbreaking book, based on thirty years' research, takes an important step past this idea. The Spirit Level shows that there is one common factor that links the healthiest and happiest societies: the degree of equality among their members. Not wealth; not resources; not culture, climate, diet, or system of government. Furthermore, more-unequal societies are bad for almost everyone within them the well-off as well as the poor. The remarkable data assembled in The Spirit Level reveals striking differences, not only among the nations of the first world but even within America's fifty states. Almost every modern social problem ill-health, violence, lack of community life, teen pregnancy, mental illness is more likely to occur in a less-equal society. This is why America, by most measures the richest country on earth, has per capita shorter average lifespan, more cases of mental illness, more obesity, and more of its citizens in prison than any other developed n...

Ever felt the need to urgently check the leveling of a surface but didn't have a spirit level handy or lazy to download an app? Then this is just for you. If you Google 'bubble level' or 'spirit level' on your phone's browser or the Google Search app, you will instantly get a spirit level that works with the magnetometer on your phone, assuming it has one. You can keep a device flat on its back to check overall level or sideways to check horizontal tilt. Do keep in mind your phone's magnetometer needs to be properly calibrated for this to work and that any bumps on the back or side (cameras, buttons) will automatically unlevel the phone and mess up your reading. For any serious work you should be using an actual spirit level since the ones on phones could go whack for a number of reasons but for a quick, casual check this should work fine.
