Vernier calliper is a popularly used precision instrument that is especially designed to gauge the depth and dimensions of diverse types of objects. This tool can be used to measure the accuracy of one-hundredth of a millimetre, as well as one-thousandth of an inch. A Vernier calliper features two sets of jaws, one on its lower side and another on its upper portion. This tool comprises of a fixed main scale and a moving Vernier scale. Vernier callipers typically show metric or imperial measures, however some of the contemporary designs of this tool measure in both. This precision instrument is known to be especially useful for measuring the diameter of various types of circular objects, such as cylinders. The reason behind this being that the jaws of this instrument can be perfectly secured on both sides of the circumference of a circular object. People needing this precision instrument can easily choose to purchase Vernier calliper online through the website of any company specializing in selling industrial and business supplies.
Types of Scales on a Vernier Calliper
A Vernier calliper features two distinct types of scales. The main scale of this precision instrument can ideally be found on the length of the calliper and tends to function in a manner similar to a ruler. This scale is fixed on the instrument and cannot be moved. This instrument additionally has a movable Vernier scale, which is divided into 10 sets, each having an equal length. This movable scale is known to be the secret to the instrument’s precision.
Uses of Vernier Calliper
A Vernier calliper is commonly used in engineering schools and scientific laboratories where precise measurements are extremely vital. The extremely high precision level of this tool does not leave much room for errors. This instrument tends to be a key component of woodworker’s toolsets as it comes in handy when dealing with diverse projects that need careful and precise measurements.
Here are three of the major uses of a Vernier calliper:
1. Measuring Inside Dimensions: The upper set of jaws featured on this precision tool can be used to measure inside dimensions, such as the diameter of a hole on a piece of metal or wood. In many projects and applications measuring of the precise diameter of holes in hollow objects like pipes and cylinders is required. In order to get a precise measurement, the jaws of a Vernier calliper can be just slid into the relevant hole, and the needed measurements can subsequently be taken from there.
2. Measuring Outside Dimensions: The outside dimensions basically refer to the things like the outer diameter of a cylinder, and the total width or length of an object. In order to measure the outer diameter of an object with the lower jaws of a Vernier calliper, people would be required to clamp these jaws around the object. However, for measuring its width or length, the relevant object has to be placed between the calliper jaws.
3. Measuring Depth: The Vernier calliper features a depth probe on its rear part, which subsequently can be extended from the edge of the hole through to the other end in order to take accurate measurement.
