Various measuring tools have been developed over the years to serve different purposes. From laboratory activities, construction, and cooking, to woodworking projects—these tools are indispensable to almost any industry!
If you’re unsure which to use for your line of work, our engineering team has listed the types of measuring tools available today and their specific uses.
Analog Measuring Tools
#1: Angle Locator
As a manual tool, an angle locator can be found in most construction sites and woodworking or carpentry shops. As the name implies, it calculates angles, ranging from 0 to 90 degrees.
Albeit limited, an angle locator is one of the best measuring tools to use for accurately recreating angles of slopes, corners, etc. This also comes highly recommended to measure angles in small spaces.
The reader is placed on the two ruler-like ends, which will determine the angle. These are also equipped with a magnetic foundation that will make it easier to attach to metal materials.
#2: Bubble Inclinometer
A bubble inclinometer determines how steep an incline is. It functions much like a lever. You simply place the bubble inclinometer near the joint you wish to measure.
Simply set the bubble inclinometer to zero. Then proceed to determine the difference as it goes through the changes.
#3: Caliper
A caliper is one of the most common measurement tools to get readings between two points. It ensure accurate measurements with its two adjustable tip points.
There are analog and digital calipers available in the market today. But, a digital caliper is more convenient when reporting accurate data. Calipers are one of the oldest measuring tools that have been in use for many years.
Vernier
A vernier caliper is a linear instrument that can recognize lengths up to 0.02 mm. It is commonly used for measurements of depth, diameter, and length.
Inside
An inside caliper is generally utilized to measure the interior of an object. It is designed with two legs that are inverted to one another. These legs are further connected by a screw and nut mechanism.
Outside
An outside caliper is generally utilized to get the measurement of the exterior of an object. It is designed with two legs that are inverted and plugged through a screw and nut mechanism.
Odd-Leg
Odd-leg calipers are also known as hermaphrodite calipers or odd-leg Jennys. It is generally utilized to mark a line at a set distance from the edge of the work. Its bent leg is run across the edge to mark the intended distance.
Divider
A divider caliper is popularly known as a compass. It is used in marking out locations on a map.
The points of the divider are sharpened to act as scribers at the same time. One of the legs is placed on the dimple from the center, and the other leg is pivoted in order to scribe on flat surfaces.
It results in the formation of a circle or an arc.
Dial
A dial caliper can report the final fraction of a millimeter or inch. This device is a small, precise rack and pinion drive with a pointer on a circular dial. It allows direct reporting, which saves users time to glance through a vernier scale.
The pointer rotates one time every inch or 1 millimeter.
#4: Compass
A compass is highly valuable, particularly for creating precise circles based on a radius or diameter. Regarded as one of the most efficient and accurate tools, it excels in bisecting angles and dividing lines in half.
#5: Level
A level is also known as a bubble level or a spirit level. It measures whether the angle is level and of equal balance. Levels are designed in various sizes and formats.
This tool is designed with one or more glass vials fixed into the level and filled with a colored liquid. The liquid will slightly fill the vial with an air bubble inside.
#6: Pressure Gauge

A feeler gauge is also known as a thickness gauge. A feeler gauge is commonly utilized to determine the clearance between materials.
This gauge is an excellent tool to calculate narrow slots, small spacing, and identifying fit between materials.
#9: Radius Gauge
A radius gauge checks the concave radius found on the corners or shoulders. It is important for layout work and inspecting components in different industries.
#10: Pin Gauge
Pin gauges are commonly utilized to gauge bore features. These are useful when measuring the straightness of a relatively deep bore.
#11: Thermocouple
A thermocouple is designed with two dissimilar conductor wires. The wires are made from different metals and are held together at one end. The resulting junction is used to measure ambient temperature.
#12: Thermistor
Thermistors [1] are known to have a considerably high coefficient of resistance. It is designed from semiconductors of the solid type. The suitable measuring range is -100 degrees Celsius to 300 degrees Celsius.
#13: Protractor
Mathematically oriented protractors are another type of device used to measure angles. It is a simple and convenient tool for making measurements. The majority of the protractors are made from plastic.
A popular industrial protractor is a digital angle gauge of a protractor. More mathematically oriented protractors can measure an angle over 360 degrees with an accuracy of 0.1 degrees. It is simply placed in between levels or surfaces.
#14: Ruler
A ruler is a very versatile measuring instrument.
It is one of the most commonly used types of measuring tools to read lengths and widths. It can also double as a device to draw straight lines.
#15: Square
Measuring squares are used to ensure that the lines made are straight. It is very convenient when you have framing projects and are required to make and find the right angle.
Most measuring squares have a fixed 90-degree angle in a variety of forms. A square is considered a good angle finder compared to other measurement tools.
Combination
Combination squares are excellent measuring tools for laying out lines for mitering, crosscutting and making notches.
The best combination squares have a 90 and 45-degree fence which allows you to slide along the blade. The square can easily identify right angles. This further allows you to record a distance accurately and hold it in place.
Drywall
A drywall square is recommended for laying out cut lines placed on standard sheets of plywood and other board materials. A drywall square can also be used as a guide when cutting board materials.
