When it comes to metrology, nothing matters more than accuracy. That’s why it is important to invest in high-quality calibration equipment if you are in the metrology industry. But even then, regular calibration is vital because even with the most advanced equipment, you risk inaccuracy anytime you ignore regular calibration. What then follows are losses, botched expenses and costly expenses. To fully appreciate the importance of regular gage calibration, one needs to first understand what calibration is and how the whole process works.

Small, sleek, light, and accurate – these are some ways to describe the digital micrometer. It gets better with the fact that you can slip it into your tool belt or shirt pocket. Alongside calipers, the digital micrometer is the most popular, effective and reliable measurement and inspection tool. This is despite the proliferation of new and technically advanced equipment that at some point threatened to make the digital micrometer moot in modern manufacturing. So, just how effective are digital micrometers? What makes it special?
Snap gages are basically go/no go gages that measure outside diameters. Their appearance is similar to micrometers. A snap gage also features anvils that can be found on a micrometer too. You should keep in mind that snap gages come in an array of sizes and shapes. There can be types A, C, and U, and the gages may come with dial or digital indicators. Apart from measuring outside diameters, snap gages can be used for measuring widths and groove diameters. In this post, we will focus on one of the main variations of snap gages – adjustable snap gages. You will learn how to master this extremely useful gage.
Air gaging is known as a contact-free form of gaging. It is a stellar option for measuring extremely thin-walled parts of soft materials. Other common applications include measuring straightness, center-distances, squareness, tapers, average diameters, and more. Air gaging is accurate, fast, and readily used in a wide range of production environments. In addition, its tooling has largely remained the same over the years, i.e. precision orifices with steel rings or tubes that set up a distance/pressure curve when in use. Here is a further look at how air gaging has evolved over the years.
Air gages stand out as one of the most effective measuring devices ever made. The device has come a long way, with its history dating back to 1919 when it was invented. The rest as they say, is history. It simply transformed metrology for the better. It developed through the years, with innovations making the device better and better. It is worth noting though, that the air gages used today do not differ so much from the first one invented in 1919. The concept is still the same. So, why in the first place is the air gage important?
One of the general-purpose tools that technicians use to measure precision parts is a height gage. These gages can measure the roundness, roughness, waviness, diameter, length, and thickness of a wide range of objects and materials. Today, almost 90 percent of height gages are utilized for surface plate work, including surface metrology (for analysis of features and textures) and surface analysis.
A height gage is a type of gaging system used to measure the height of various product features. The four main types of height gages include micrometer height gages, vernier height gages, surface height gages, and electronic (or digital) height gages. Electronic height gages are designed to capture and display metrology data in alphanumeric or numeric form. Indicators, calipers, and micrometers are also known to come with digital displays.
With all of the types of height gages available, and with each of their matching applications, it might be hard to decide which one is the most appropriate for you. Which gage will meet your needs? The following will hopefully help you distinguish between not only the different types of height gages but the various purposes for which they were designed.
The Mahr Federal Maxum III Digital Comparator will be the focus of this piece. But, first things first – what is a digital comparator? Also referred to as a magnitude comparator, it is a device classified casually as a hardware electronic. It is used in MCUs (microcontrollers) and CPUs (central processing units). It determines whether one number is equal to, less than, or greater than another number. (Two numbers are taken as input in binary form.)
Digital height gages sometimes get a bad rap. People refer to them as nothing more than a giant-sized caliper based, apparently, on its range of motion. But there is so much more to a digital height gage than that. It is, without a doubt, a benchtop gaging measurement system of the most sophisticated and accurate nature. Not only that, the multitude of tasks that it can perform reliably and quickly are impressive.
