What is Calibration & Why is it Crucial for Measuring Devices?

Measurement is a core part of practically everything. Whether you’re at home trying to level out your wall hangings, or you’re operating a multi-million-dollar manufacturing facility.

However, it’s not as simple as picking up the appropriate measuring tool and getting to work. Pretty much any measurement tool, if you want spot-on readings, needs to be calibrated before you use it. 

So, what is calibration, and why is it so crucial for accurate measurements across nearly all science and technology fields? Let’s take a closer look.

What is Calibration?

Calibration is a fairly simple concept that can be a bit more complex in practice if you don’t have experience with it.

Essentially, you’re using a known standard, usually an already calibrated tool, to check the accuracy of another measurement tool.

For example, let’s say you’re measuring temperature in a fairly precise field. You’d need to test it against something you know is accurate. 

An old standard is freeze-temp water to set built-in calibration features, but you could also use a thermometer that you already know is accurate and compare the readings of both.

Then, you would adjust the calibration of the second thermometer to match the one that you know is accurate.

What Types of Measurement Tools are Calibrated?

We used a thermometer as an everyday example. Most people have purchased a new meat thermometer and had to go through a calibration step. However, pretty much every measurement tool needs to be calibrated in some way.

Precise manufacturing equipment, levels, thermometers of various complexities, accelerometers, colorimeters, and more need to be calibrated before they’re used. 

Even the lowly right-angle square, one of the simplest measuring tools, needs to be compared to a known right angle to determine its accuracy and usefulness.

Why is Calibration Crucial in Measurement?

So, why exactly is it so important to calibrate your measurement tool? Shouldn’t it be accurate right out of the box?

Well, a manual hand tool, such as a ruler, should be accurate out of the box. Otherwise, you bought something that doesn’t work. You still need to test it, though.

Calibration is typically associated with more complex measurement tools, including electronic devices like electromagnetic field measuring instruments used in specialized industries. 

Especially if they’re used in highly precise applications and meant to be adjustable, because they can lose calibration over time and use.

Calibration allows you to dial in the measurement and ensure that every time you use that tool, you measure the piece with 100% precision.

Without calibration, the standards and tolerances achieved in modern applications would be impossible. Even an 8th of an inch’s worth of inaccuracy would render a lot of things useless or completely change the intended results.

Again, with a thermometer, imagine you’re in the culinary field and need to rest a steak exactly to 145 degrees for the perfect presentation. If the thermometer is off, that steak goes from medium rare to medium with just a moment of overcooking.

Similarly, tools like lux meters, which measure light intensity, must be precisely calibrated to ensure correct readings in industries like photography or architecture.

In an application such as medicine manufacturing or architecture, the consequences can be a lot more serious.

A Beginner’s Guide to Common Scientific Tools for Measurement

Scientific measurements require a lot more than just a tape measure, ruler, or other simple form of measurement that every homeowner or hobbyist uses constantly. 

If you’re just getting into a field that uses scientific measurement professionally, it can be a bit overwhelming to see the complex tools you’ll be working with.

To help with a few of the basics, here are some essential tools for measurement that you’ll likely need as you move forward in your scientific work.

1: Vernier Calipers

Vernier calipers are used to measure along a straight plane, similarly to a ruler, but it’s a lot more complicated than that. A measurement scale known as a Vernier scale slides up and down the main piece.

This allows for the precise measurement of depth, distance, length, width, and more without all the issues that come with using a tape measure, ruler, or similar simple tool.

Most often, it’s used for taking scientific measurements in the engineering field.

2: Micrometer Screw Gauge

A micrometer screw gauge is one of the most important tools for measurement in an engineer or machinist’s arsenal. It’s used for the same measurements as vernier calipers, but it measures even smaller dimensions.

In modern engineering and machine work, tolerances are excessively small, and it’s important to meet those unbelievably low tolerances for a variety of reasons. Many of today’s products and structures couldn’t exist without them.

A micrometer screw gauge is a calibrated screw mechanism that is used to measure tiny dimensions that other options simply can’t measure accurately. It’s a simple concept with a twist of a screw doing all the work, but it’s a tool that modern engineering wouldn’t exist without.

 

3: Graduated Cylinder 

A graduated cylinder is one of the most common tools for measurement used in industries that require accurate liquid measurements. It’s an essential piece of scientific measuring equipment, and many of the consumables you take for medicinal purposes wouldn’t be possible without it, or they’d be incredibly unsafe to use.

Coincidentally, it’s also incredibly simple to use. It’s a piece of glassware that’s tube-shaped, and it’s marked vertically at precisely measured intervals. This lets you measure the volume of a liquid. It’s a lot like the measuring cup in your kitchen, but it’s far more accurate and used in much more precise applications.

4: Accelerometer

Compared to the other tools for measurement we’ve talked about, the accelerometer is probably the most sophisticated and advanced. It’s used to measure the acceleration of different materials.

If you have a modern smartphone, you have an accelerometer in the palm of your hand.

The measurements for these are used for a variety of applications, but most notably, they help time mechanical functions extremely precisely.

5: Colorimeter

A colorimeter is an electronic measurement device that is used when making a chemical solution. It helps you determine how concentrated each component is, and it’s used in a wide variety of applications across a variety of industries.
