The level is one of those tools considered to be a must-have for any contractor, builder, and even DIYer. Don’t be mistaken that its main purpose– to determine whether a surface is a level or plumb– isn’t that critical. After all, being off by an inch in any construction job can lead to disastrous results. With a level, you can level floors, align and plumb walls,檢查門的高度andwindows, and check masonry alignment, among others.
市場上有許多類型的級別可用，雖然有些是多功能足以在不同的情況下使用，但大多數時候，這些類型的級別都是為特定用途而設計的。

Main Types of Levers
Levels can be categorized into four main types– spirit or bubble levels, water levels, optical levels, and laser levels. These four main types can then be broken down into sub-types.
Let’s take a look at the four main types of levels first.
Spirit or Bubble Levels
精神或氣泡水平包括含有酒精和氣泡的密封玻璃管。管的頂部被鞠躬，以至於當水平下方的表麵是水平的時，氣泡將在中間休息。這已經存在了一段時間了，現在已經在1661年發明了。它最初在測量前使用望遠鏡。
水平
Meanwhile, a water level is used to match elevations of locations that are too far or distant for spirit levels. Surprisingly, this tool has been in existence far longer than a spirit or bubble level, having been used in ancient civilizations. It works on the idea that water will always seek its level.
A water level has two cylinders that are placed on top of two surfaces that need to be level. The containers are linked by plastic tubing lying below them. The idea works simply like this: if the two surfaces wherein the cylinders are placed are of the same height, then the water inside the cylinder will be level. If not, then it only means that one surface is lower than the other.
This tool is commonly used by carpenters, contractors, plumbers, and other landscapers. It can be used in locating a dropped ceiling or lining up a deck. It can also be effective with objects separated by trees, rocks, or other obstacles.
Optical Levels
第三種主要類型是光學水平。這是一種最常用於測量的水平。它有助於施工專業人員在衡量陸地海拔。DIY愛好者可能不太可能使用。
Laser Levels
Finally, there are the so-called laser levels. This kind of level has a laser beam projector emitting a beam onto the surface to set up a level plane. Some advanced models can show the vertical or plumb level for enhanced accuracy.
As mentioned earlier, these major types of levels can even be broken down into sub-types. Continue reading to know more.
水平的子類型
Box Beam Levels
Box beam level is a type of spirit level. Sometimes called a box level, it got its name from the shape of the level frame. It usually has handles or grips towards the middle and is intended to make it easier for users to hold it. This type of level is primarily used by framers and carpenters for tasks ranging from repairing and installing doors, repairing walls and floors, and building structural framing, among others.
Each vial on this type of level has two marks with the bubble in between the two points. These marks are used in determining if a surface is plumb or level. A box level can make both horizontal and vertical measurements.
要水平測量，將工具放在水平表麵上並保持穩定。然後，氣泡將在小瓶的標記之間移動，直至其穩定。但如果泡沫出現在小瓶的左側，那麼這意味著物體的左側太高。如果氣泡顯示在標記的右側，則表示右側不等於另一側。泡沫應該正處於兩個小瓶標記的中間，用於物體是完美的水平。
A box level can also be used in measuring upright surfaces like walls and doors. Similar to using it vertically, the surface is determined to be vertical if the bubble appears right in the middle of the vial’s marks.
Magnetic Levels
A magnetic level is a type of spirit level with one or more magnets placed to the underside, allowing it to attach to metallic surfaces. Up to three vials can be placed for horizontal and vertical measurement depending on the model, length, and manufacturer of the magnetic level.
This type of level is used in setting up, aligning, and adjusting structural elements like beams used in construction. It can also be used when installing steel structures in scaffolding. It may also come in handy in drywall installation, allowing users to ensure that ceiling and wall profiles are correctly aligned.
The addition of magnets to a level is useful to a commercial carpenter or contractor as he would simply stick the box-beam level to a surface to check if the object is level. But it won’t be useful in determining if other materials like cement or wood are plumb. Box-beam levels are also often available in digital form for more precise or accurate measurement and reading.
Digital Box Levels
很容易認為數字箱電平與盒子級別相同。畢竟，兩者都有相同的案例和建設。然而，主要區別在於數字箱電平具有數字讀數，使用戶可以測量到第四個小數位。這使數字箱級別提供更精確的讀數。這是您需要精確測量的工具，或者在讀取精神級別的泡沫瓶中有問題。
I-Beam Level
As its name suggests, an I-Beam level is shaped like the letter “I,” with the beam consisting of two horizontal planes called flanges. These are connected by a solitary vertical component called the web.
An I-Beam level is a versatile type of level that’s widely used by contractors and builders, particularly in ensuring the integrity of a structure.
與數字箱電平一樣，I-Beam級通常被誤認為是一個盒子級。但這兩個工具之間存在許多差異。最大的區別是重量，因為I-梁輕輕，這使得考慮到他們必須攜帶的許多工具使其成為建築商更理想的工具。當然，輕量級也意味著I-Beam水平並不像箱梁水平那樣堅固。與盒梁電平不同，I-Beam水平更容易發生裂縫和斷裂。
Another difference is the shape. As mentioned earlier, an I-Beam level is shaped like the letter I. On the other hand, a box-beam level is built like a box with handles or grips for easier handling.
然而，I-Beam水平和盒子層實際上是相同的目的。由用戶決定哪種工具更適合用於特定場合。
Screeding Level
A screeding level is a tool you’d want to ensure that the new concrete you’re putting in is smooth and level. It can also come in handy in leveling sand as well as paving stones. This is the tool that most contractors use when working on walkways, patios, and driveways.
This is a long and narrow tool that’s bulkier and heavier than most levels. The design and body make it ideal for the laying of floors. It can also be useful in plastering, although the bulk makes it difficult to maneuver on vertical surfaces.
該工具從冗長的或最終的sta而得名ge in floor and wall coatings. Screed pertains to any flooring product, usually a concrete mixture, that serves as the top layer of flooring. In short, a screed is a finishing coat.
This type of level is available in various lengths, although the most common are the ones between 6 and 10 feet. The choice of length would depend on the task that you are doing. It has handles that come in the form of slots, allowing users to easily handle and carry it around. The design of the handles also means that these won’t get in the way of the straightness of the tool.
Of course, a critical component or part of this level is the vial similar to those found on spirit levels. A screeding level is a spirit or bubble level.
Torpedo Level
有時，你會發現自己在狹小的空間工作，但你仍然需要確保表麵是鉛筆鉗。魚雷級別是您需要的級別。
A torpedo level is small— about six to 12 inches long, with vials that can indicate level, plumb, and even 45 degrees angles. Its body is commonly made of plastic. It usually has two or three tube vials that have yellowish-green additives to determine surface level.
由於其尺寸，它是在狹小空間工作的最佳工具。它可以在調平圖片中有用，確定管道斜坡和短距離水平。盡管小，但魚雷水平非常準確。
它還配備帶夾，使其更容易攜帶。它甚至可以夾在袋子和皮帶上。魚雷水平的另一個常見特征是外部中的V形凹槽。這適合管道，以確定它們是否垂直或水平裝配。有些型號具有強大的磁鐵，允許它們粘在金屬表麵，腳手架和金屬管中。帶磁鐵的魚雷水平也可以使用免提。
Related to this type of level is the specialty torpedo level, which features certain qualities which may be deemed a luxury for some users. A specialty torpedo level has a single, rounded end and three sides that are square-shaped. It can be used in taking accurate measurements of small or rounded spaces, such as the beveled corner of a wall.
The scaffold level is yet another variation of the torpedo level. It is best for erecting scaffolds as it has magnets that can be attached to the surface. It is also a type of level commonly used by plumbers and other workers who work with metal surfaces and pipes.
String Level
字符串級別是如果您必須在長距離跨越級別，則使用該工具。將這種類型的水平放置在一塊繩子上，該繩子在兩個帖子之間伸展。拉動字符串，以便確定兩個帖子之間的電平。它具有比使用傳統水平長距離采用多重測量的更實用的方法。
Carpenter’s Level
A carpenter’s level is commonly a two-feet long tool with a wooden frame and one or more bubble tubes. The wood is often made from stable wood species like ebony, mahogany, rosewood, andcherry wood. It is usually three inches high and an inch deep.
The bubble tubes have two notches, one of which consists of a small bubble that indicates if the tool is level. You may also find other carpenter’s levels in different lengths like 4 feet and 8 feet for measuring various heights and lengths.
This is one of the more popular levels for DIYers because it’s ideal for use at home. You can use it for building furniture and decks, checking the condition of floor molding, calculating angles on a sloped surface, and hanging photographs or paintings on the wall.
梅森的水平
The mason level is best used in crafting and installing cabinets. It is longer than a carpenter’s level, with its shortest version starting at four feet. The extra length is because a typical mason needs a longer level for laying brick and stone.
Bull’s Eye Level
這是一種專為二維輪廓設計的精神級別。它通常用於建築工地，特別是由木匠。它也可以在家中用於某些需求。
例如,如果你想要一個廚房cookto水平p, simply place this level in the middle of the surface. You will then have to adjust the surface until the bubble is in the center of the circle.
It has also been adapted or used in camera tripods, compasses, and similar devices that must not tip into certain directions.
帖子級別
This is an L-shaped level consisting of a bubble vial found on the spine and each wing. It usually comes with magnets, so it would easily attach to metallic surfaces. It is a specialized leveling equipment that’s useful in constructing decks, porches, and other fixtures consisting of posts, hence the name.
交叉檢查水平
This is a pocket-sized tool that is also known as 2D level. It consists of a couple of bubble vials at right angles to each other. It is useful in checking horizontal and vertical planes. It is primarily for household use like leveling appliances and electronic equipment.
Spot Laser Level
This is a type of laser level that you can use in installing crown moldings or hanging pictures. It is affixed in a set position for projecting a horizontal line of light. The beam of light is then used in marking positions.
A spot laser level is cheap and easy to use. The downside, however, is its accuracy. It’s not surprising that it’s primarily used at home and not in construction sites, where accuracy is of vital importance.
Cross Line Level
牆上的十字架這個級別項目,因此它的name. It is static yet can be moved using your hand, allowing it to point from one side of the wall to another. It is a bit more expensive and accurate than a spot laser. Like the spot laser, you can use a cross line level in hanging hooks, putting up pictures, shelves, and other things on the wall.
激光鉛線
Another type of laser level, the laser plumb line, works similar to the cross-line laser level and spot laser level. But the difference is that this one shoots up a beam of laser light. It is ideal for vertical alignments and measuring depths, even on windy days.
旋轉激光水平
這種類型的激光電平由鏡子和激光器組成。它突出圍繞水平麵旋轉的光束。它可以通過升高或降低激光水平來允許您標記各種各樣的點。這最適合調平窗戶，門和製作麵板。
Conclusion
Levels are versatile and essential tools you’d want to have when working on a DIY project. There are lots of levels that you can choose from, as you have realized after reading this article. Knowing your needs, budget, and types of tasks you often work on should give you an idea of which type of level to pick up.
