In the manufacturing industry, it is essential to have precise and exact measurements of the objects that are produced. Determining the dimensions of an object is a key process to ensure high quality and precision in production. To achieve this, it is necessary to carefully select the appropriate measuring instruments. There are different types of instruments used to measure the dimensions of an object, and the correct choice depends on the type of object and the precision required.
One of the most common instruments to measure dimensions is the vernier caliper. This instrument allows you to measure both internal and external lengths with great precision. The vernier caliper has a main scale that shows measurements in fractions of inches or millimeters, and a secondary scale (vernier) that slides on the main scale to achieve more precise measurements. It is ideal for measuring small, precise objects, such as electronic components or jewelry.
Another widely used instrument is the micrometer, also known as Palmer's screw. This device is especially useful for measuring extremely small dimensions, such as the thickness of a sheet of paper or the diameter of a wire. The micrometer consists of a fixed head and a moving head, joined by a screw that allows a delicate and controlled movement. When measuring, the user turns the screw until the two heads are in contact with the object to be measured, and then the measurement is read on the corresponding scale. The micrometer offers exceptional precision and is used in applications that require high-precision measurements, such as manufacturing of mechanical components or scientific research.
In summary, to determine the dimensions of an object accurately and reliably, it is crucial to select the appropriate measuring instruments. The vernier caliper and the micrometer are devices widely used in industry to measure internal lengths, external lengths, and extremely small dimensions, respectively.

- Vernier Caliper: This measuring instrument is more precise than a ruler, since it has a millimeter scale and allows you to measure internal, external and depth lengths. It is used by sliding the caliper until it fits the object to be measured and then reading the value on the scale.
- Micrometer: The micrometer is a measuring tool that allows you to achieve measurements with great precision. It is used to measure small dimensions, such as the thickness of a wire or sheet. The object is placed between the arms of the micrometer and closed until it fits snugly. The measurement is then read on the precision scale.
- Laser: Another technique used in measuring linear dimensions is the use of a laser. This emits a beam of light that allows determining the "distance" between two points. A laser meter is used, which projects a laser point onto the object to be measured and records the length of the beam to the destination point.
- Three-dimensional metrology: when it is required to measure dimensions in three dimensions, three-dimensional metrology is used. This technique uses coordinate measurement systems that allow precise measurements to be achieved in the three spatial axes. Coordinate measurement machines (CMM) or 3D scanners are used to make these measurements.
