There are many different kinds of measuring instruments, each with its own uses and applications that are widely recognized in the general population. Depending on the website, specific groups are more likely to see certain types of measuring instruments than others. There are a lot of things we can learn about the many kinds of measuring equipment and how they work.

Measurement is the action of acquiring and comparing quantities of certain items in domains such as physics, quality assurance, and engineering. The measurement provides a number that is relevant to the item being studied as well as the referenced measurement unit. The mechanisms by which these numerical relations are obtained are measuring tools with faultless methods that describe their use. Well, in this article, I will be discussing the most common and important types of measuring tools every engineer must endeavor to have.

Let’s dive in!

Types of measuring tools

The types of measuring tools include speedometers, measuring tape, thermometers, compasses, digital angle gauges, levels, laser levels, macrometers, measuring squares, odometers, pressure gauges, protractors, rulers, angle locators, bubble inclinometers, and calipers.


A speedometer can also be listed among the common types of measuring tools for determining and displaying a vehicle’s immediate speed. In the early twentieth century, they became available as alternatives. Since around 1910, these have been often fitted to motor vehicles and used as standard equipment.

The speedometer’s speed-indicating mechanism is powered by a round magnet that rotates 1,000 times each mile of vehicle travel. Other vehicles’ speedometers have different names and employ different speed-sensing standards. These measuring tools can be classified among the precision measuring equipment.


Measuring Tape

A tape measure is a versatile ruler that can be folded into any form and used to measure length or width. In their most basic form, they are made up of a fabric or plastic ribbon with measures in inches, centimeters, and/or millimeters written on it. that

Tape measures with lengths of 12 feet, 25 feet, or 100 feet are the most frequent. Its shape makes it easy to carry huge length measurements in your pocket while also allowing you to measure curves and corners. Today, it may be found almost anywhere, even in miniature as a keychain fob or novelty item.

Thermometers are special types of measuring tools used to measure temperature, as the name implies. It is necessary for a variety of activities such as manufacturing, scientific research, and medical practice. Thermometers are often inexpensive, long-lasting, accurate, and simple to calibrate.

It is made up of two parts: a temperature sensor that changes as the temperature changes, and a way to transform that change into a numerical value. Thermometers are widely employed in technology and industry, meteorology, medicine, and scientific research to monitor processes.



A compass is a very useful measuring tool that may be used for a variety of tasks such as algebra, drafting, navigation, and other things. If you’re an architect, you’re probably already familiar with the concept of a compass. It is extensively utilized in the shipbuilding and carpentry processes.

Compasses are usually made of metal and have two “legs” that may be adjusted to change the radius of the circle drawn. A compass is a technical drawing instrument for writing circles and arcs. It can also be used as a divider to separate distances, especially on maps, as a divider.



Digital angle gauge

Angle gauges were established because it is critical for workers to measure angles and they want reliable data. These types of measuring equipment make it simple to measure any angle surfaces that are attached to them.

A digital angle gauge is faster, easier to operate, and more accurate than an analog angle gauge. It includes a powerful magnetic base as well as automatic calibration settings for establishing the correct bevel and miter angles on powered saws. They’re not only inexpensive, but they’re also extremely precise.



A level is a form of measuring instrument that’s used to show the horizontal plane. The level is an optical instrument that displays measured findings by using air bubbles in a liquid media. The tube is sealed and attached horizontally to a smooth-bottomed block of wood.

The level’s glass tube is slanted, and the movement of the bubble indicates the horizontal adjustment. Longer-level instruments, ranging in length from two to six feet, are commonly used by builders. Construction, woodworking, and metalworking shops all employ them.


Laser Level

A laser level is a measuring device that consists of a spinning laser beam projector that can be secured to a tripod. This is leveled according to the tool’s accuracy, and it projects a fixed red or green beam in a plane around the horizontal and/or vertical axes.

Certain varieties can measure the distance between the unit and the laser beam’s terminus, providing a quick and precise worksite distance measurement solution. In the construction and surveying industries, laser levels are extensively utilized for leveling and aligning applications.



These types of measuring tools look like a caliper, but instead of sliding, it screws down. The spindle is extremely accurate, and the measurement object is put between the spindle and the anvil. The ratchet knob is adjusted to revolve the spindle until the object is measured. They are sometimes known as screw gauges in addition to the word micrometer.

The work distance between their two caliper heads is quickly measured with digital micrometers. A micrometer, along with other metrological devices such as dials, verniers, and digital calipers, is commonly used for precise component measurement in mechanical engineering and manufacturing, as well as in most mechanical trades.


Measuring squares

A square is a type of measuring tool that is used to measure and refer to a 90° angle, whereas a miter square is used to measure and refer to a 45° angle. Two straight edges positioned at right angles to each other make up a square measuring device. Combination squares, drywall squares, framing squares, and speed squares are just a few of the special types of these tools.

Carpenters and machinists typically use them to evaluate the precision of right angles when drawing lines on the material before cutting. A scale (ruler) for measuring distances or calculating angles is one sort of square measuring device.

The odometer is a type of measurement device used in automobiles to determine how far a vehicle, such as a bicycle or a car, has driven. A car’s distance traveled is utilized for a variety of purposes.

It can be made electronically, mechanically, or by combining the two methods (electromechanical). Mechanical odometers, which are installed on a flexible cable consisting of a tightly wound spring, are the most prevalent. These odometers are being phased out in favor of digital odometers, which have more functions and are less expensive but are not nearly as accurate.


Pressure gauge

The analysis force applied by the fluid on a surface is measured by the pressure methods. As a result, the pressure gauge is used to measure and show the fluid pressure in a single unit. The force per unit of the surface area is how pressure is measured.

Everything from height to air pressure to depth to blood pressure is measured with pressure gauges. A pressure gauge has the advantage of being easy to see and frequently appearing on the screen quickly. The most prevalent forms of analog pressure gauges are hydrostatic and aneroid gauges.

Protractors are half-circle-shaped measuring devices often constructed of plastic or glass. These are commonly marked with degrees and are used to measure angles. More mathematically oriented protractors that measure in radians can be found on occasion.

A common protractor is shaped like a semicircle, with an inner and outer scale with marks ranging from 0 to 180 degrees. Engineers and designers use a tool called an angle protractor to get more precise measurements. A bevel protractor is a more advanced variant of a protractor that has one or two swinging arms for measuring angles.



A ruler is a tool used to measure distances and draw straight lines in geometry and technical drawing, as well as in the engineering and construction sectors. In the commercial world, they’re generally employed in engineering to ensure accurate measurements on flat surfaces. Both metric and customary units are used to measure a ruler. The usual distance above the ruler is in centimeters, and below it is in inches, with the hash mark indicating the spacing in the ruler. Rulers are arguably the most widely used measurement tool in today’s world.


Angle locator

An angle finder is another name for an angle locator. It’s the ideal instrument for measuring angles and replicating an existing area’s angle. These are frequently used in construction and carpentry. The magnetic base of these measuring tools allows them to be mounted to metal measuring sections. It’s a digitally displayed manual tool.

To determine your angle, place the ends of this angle locator on the workpiece and utilize the readings acquired. Angles from 0° to 90° can be measured quickly and easily with the angle locator. When you need to determine an angle within a closet or a tiny place, having a tool like this will make the job much easier.

Bubble inclinometer

If you need to determine a specific inclination, an inclinometer is a must-have tool. These are specifically developed to measure a joint’s range of motion as well as the grade’s stability.

Set the bubble inclinometer to zero to determine the range of motion of a joint to be measured, and then determine the difference as it changes. Sports therapists frequently use it to check for a healthy range of motion at key points on the body.



A caliper is a type of measuring tool that is used to determine the thickness, outside and interior diameters, length, width, and depth of an object. These measuring tools are usually made of steel and provide several dimension measurements. They’re used in a variety of industries, including engineering, medical, building, home improvement, and metallurgy.

The whole length can be simply measured using a fixed ruler by adjusting the tips of the calipers to fit across the object to be measured and then removing the calipers. Calipers come in a variety of styles that allow you to read measurements on a controlled scale, dial, or digital display.

In addition, calipers are tools for measuring the separation between two surfaces of an object. The caliper is removed and the reading is obtained by measuring the distance between the tips using a measuring tool, such as a ruler, after the tip of the caliper has been adjusted to fit the points being measured. There are numerous varieties of calipers, including outside, inside, spring, transfer, and hermaphrodite calipers.
