9 Useful Measuring Tools

The sound level meter, subler, thermometer and compass are just some of the measuring devices used every day, in various fields of activity, so that everything comes out perfectly. Find out in this article what other tools in this category are on the list of the most popular and useful.


Measuring instruments are essential in carpentry, carpentry, furniture production, construction, army, industry, engineering and design and a variety of other fields, including everyday life. Because the available models are as different as the purposes and activities in which they are used, we present in this article some of the most popular options.



Known to most of us in geometry classes, the protractor is a small, plastic instrument, very affordable, used to measure angles in a variety of fields, from math and architecture to engineering. Its big disadvantage is that it relies on the human eye to observe results, which means lower accuracy and the possibility of errors. But there are also digital alternatives designed for areas where a very high degree of accuracy is needed.

Geologists, designers and navigators also use a category of instruments dedicated to measuring angles called inclinometers, which aim to directly assess the angle of inclination of an element.



It is one of the simplest measuring devices, it is present in most homes and useful in a variety of activities. It includes a strip graduated in centimeters or inches, depending on the metric system used, similar to a tailoring meter, framed in a support made mostly of plastic, which ensures rolling and protection.

The outer end is provided with a metal element that prevents complete penetration into the support and allows easy pulling of the graduated tape.



It is an electronic device used to measure the thickness, depth or width of objects. As the name suggests, we are talking about small items, for which accurate size assessment is important. It is most often used in the machinery and equipment industry, along with other metrology tools.

There are several types of micrometers, specialized depending on the characteristics of use. But the most useful thing is to know that if you need one, you can choose a mechanical version, a little more delicate to use, but which does not depend on batteries and which you can use in conditions less favorable to electronic devices, or the digital version, easier to read.



As a shape, the subler makes you think of a double F, with two larger horizontal segments on one side, designed to measure the outside, the thickness and width of objects, and two smaller ones on the opposite side, which help you assess the diameter. a hole or the depth and width of a channel. Most subler models for measurements are made of resistant metal, this instrument being used to evaluate planks, metal sheets, tiles, pipes, etc.


Smooth out

This tool is used to check if a certain element is placed upright (shelf, door, wall, etc.). It is frequently used in construction and carpentry and is currently available in two main variants.

The simple level uses a liquid tube, an air bubble and gravity to evaluate the position of the evaluated structure and requires direct contact with it (wall, board, etc.), while laser options can be used remotely.

Some laser models also allow 360-degree verification, meaning that the laser beam can be projected onto more than one wall, inside a building, and measuring the distance to the object being studied.


the meter

If you have ever looked carefully at the description of power tools such as chainsaws, drills or rotary hammers, to see how many decibels it generates and what is the risk of affecting your hearing, it is good to know that level is measured with a sound level meter. It is therefore a device equipped with a sensitive microphone, amplifier and voltmeter, whose role is to measure sound pressure.

It is used to determine the level of noise pollution both in inhabited areas and especially in certain areas of industry and airports.



Used to measure temperature, thermometers are divided into medical and industrial, contact and infrared. If the medical ones are a permanent presence in the house, especially in families with small children, the ones used in the industry are specialized models that allow the measurement on a much higher temperature range. The latter also differ in terms of the sensors used and the environment in which they can operate (liquid, high temperatures, etc.).

You can also use such an instrument in the house, to identify the areas where the electric cables heat up, the heat losses in the house due to insulation problems, the cold spots where mold can develop, etc.



Used in environmental studies, but also in locations where it is built, in museums and other spaces with objects sensitive to moisture, as well as in homes, the hygrometer analyzes and indicates the concentration of water vapor in the air. You need such an instrument if you have signs of dampness and mold in the house, or you wake up in the morning with a dry and irritated throat.

They are electronic devices, which work with batteries, available in formats for household use, of lower precision and sometimes included in humidifiers or dehumidifiers, and in industrial and scientific models, with superior accuracy and multiple functions, which allow the control of evaluation conditions.


Compass or compass

Used by hiking enthusiasts, well known to children enrolled in scout clubs and essential for military operations, the compass is a useful tool for determining position in the field, using cardinal points.

The simplest, pocket, are as small as coins, but help you orient yourself when traveling through nature. More complex models can be used to accurately identify the position on the map or in relation to a given landmark.
