As the world in general progresses, the technology available in the realm of metrology must keep up. Some measurement experts may align with older methods of measurement and older styles of certain tools. However, there are real advances being made in the devices available to complete the most precise and accurate measurements possible. One of those advances can be seen in the ultralight calipers now available. The traditional Vernier calipers continue to have their benefits, but there are undeniable advantages when comparing them to the newer ultralight calipers. Today, we will outline a few of the advantages of each tool and argue that the ultralight calipers may be superior.
One factor that distinguishes Vernier calipers above the rest are their ability to measure over a wide range while still providing accurate measurements. Known for their precise and accurate measurement capabilities, Vernier calipers are adaptable to a number of different measurement demands. These tools are capable of taking measurements of inside and outside dimensions, replacing the role of micrometers in a bind, as well as taking the depth measurement on various geometrically shaped parts. Vernier calipers are built with both a main and secondary scale, thus eliminating the need to an extra ruler or tape measure. These tools are also commonly built, and therefore available from a number of suppliers at very competitive and reasonable prices. Finally, most manufacturers of Vernier calipers use stainless steel. This makes these devices incredibly strong and durable, such that they could last as long as you need. One disadvantage involves reliable measurements, which can be challenging with Vernier calipers. When it comes to reliability, alignment is key and these tools can be tricky to align accurately for each measurement. With expertise, it can be done, but it is not easy.
Alternatively, ultralight calipers come with a number of advantages that set them apart from the traditional Vernier calipers. Ultralight calipers are a newer design in the field, built primarily from hollow aluminum with stainless steel reinforcement. This build is meant to be wear-resistant and assures that the beam of the device is protected from shocks. The state-of-the-art technology used to create ultralight calipers makes these tools incredibly lightweight. The lightness of the ultralight caliper actually helps to improve measurement results and makes these calipers easier to use reliably than Vernier calipers. Measurement repeatability is improved through their pressure control. Due to this control over the measuring pressure, these calipers will have consistent force on the jaws, thus ensuring greater accuracy when completing large measurements such as bore diameter.
Additionally, all faces of the ultralight calipers that come in contact with other parts are coated in titanium on either a solid carbide or hardened steel base. This ensures that the device is resistant to damages and scratches from heavy use. Ultralight calipers also come with a fixed left jaw. The fixed left jaw helps to increase rigidity and precision of the measurements taken. Vernier calipers are traditionally read manually by the operator. Ultralight calipers, on the other hand, have a digital display that further guarantees an accurate readout. The lightness of this advanced tool makes it easy to transport and simple to learn. Traditional Vernier calipers require a greater level of training for accurate use, whereas these ultralight counterparts can be learned as a faster rate without sacrificing high quality measurement.
Overall, whether you prefer the traditional Vernier caliper or the newer ultralight model of caliper, these tools are important for anyone working in metrology. The newer technology used for the ultralight calipers comes with many advantages that may make these the superior tool.
