What is the level of hand?

The

levels are used to determine whether an object is at the level of another reference point. The level of hand is a level that is small enough to fit the user's hand. This is unlike stationary levels, such as levels used by inspectors that require tripods or function assembly. The most common form of hand level is called the level of spirit and determines whether the object is in connection with gravity. Most hands levels work on the basis of an object relationship to gravity. It basically sees whether the controlled surface is perpendicular to straight down. Levels that are more complex can check the surfaces in relation to other objects and directions. These tasks are often too difficult for a simple hand level.

Ghost levels are the most common form of hand level. These levels look like small tubes or plates with a bubble in them. The bubble moves along the tube to show the relationships to the stove down. They are called the levels of spirit because they are usually full of artificially colored alcohol like ethanol,to allow the bubble to move more freely.

There are two main patterns for spirit levels: plates and tubes. The level of the plate style is a round container filled with alcohol to look down. When the user looks down at the top of the level, there are a number of circles that give the level a look like a bull. There is also a bubble that swims freely in the liquid. The level of hand in the style of the tube simply has a small tube that sits parallel to the ground; It also has a free floating bubble and a number of brands.

The bubble sits in the center of the tube or plate when the level is perpendicular to gravity. The level of the tube measures the slope below it in two directions, the axis of the tube. Measurement of plates in Four directions, basically axis of signs plus. In both cases, other lines on the measuring surface help the user see exactly how close the bubble to the center or how close the surface is at the level.

In recent years, the market forThe electronic version of the spirit level was baked. These devices contain two small tubes inside the plastic cover. The device measures the positions of the materials inside these tubes and shows the exact angle of the surface below. Although they are much more accurate, simplicity and low cost of common spirit are maintained by the most popular style of hand.
