1. What is the accuracy of the level?
The accuracy of the level refers to the axial movement of the level bubble and the inclination angle when the center of the bubble coincides with the symmetrical center of the left and right marking lines when the level is at a specified horizontal inclination angle. Generally, the accuracy of the level is related to many factors. , then what is the general accuracy of the level?
The accuracy classification of the level is expressed in numerical values, and the unit is mm/m. For example, a level with an accuracy of 0.75mm/m means that the error per m of the level is not more than 0.75mm. The accuracy of the level is generally as follows: 0.25mm/m, the angle is expressed as 0.0143°, 0.5mm/m, the degree is expressed as 0.0286°, 0.75mm/m, the degree is expressed as 0.0430°, 1mm/m, the degree is expressed It is 0.0573°, 1.5mm/m, the degree is 0.08599°, 2mm/m, and the degree is 0.1146°.
2. Is the longer the level ruler more accurate?
When measuring whether an object is in a horizontal state, a spirit level is usually used, and it is necessary to choose a spirit level with appropriate accuracy according to the needs of the job. Many friends think that the longer the spirit level, the higher the level of accuracy, so is this correct?
It is not necessarily that the longer the level is, the more accurate it is. You also need to look at the object to be measured. For example, if you measure a short object, a long level may be inaccurate. However, the level can be used for short distances. It can also be used for long-distance measurement, and it is more convenient to use. In general, the longer the level is, the more accurate it is. It also depends on the straightness of the material, the quality of the level bubble, the wall thickness of the ruler, and whether the base bottom surface has been milled. The selection can be based on the needs of the measuring object. Choose a level with the appropriate accuracy according to the actual situation.
