Vernier calipers
Vernier calipers. These are calipers (a type of measuring device) that have a Vernier scale to allow accurate measurements. Here, two sets of jaws at left are used to obtain external (lower jaws) and internal (upper jaws) measurements. The jaws are moved (using the wheel at centre left) to cover the distance to be measured. The value is read off the scale from the oval area (also at centre left), which includes the Vernier scale that allows increased accuracy of measurement. The scale here is given in both centimetres (lower scale) and inches (upper scale). There is also a moveable rod (protruding at far right) that is used to obtain measurements of depth

EDITORS COMMENTS
This print showcases a pair of Vernier calipers, an essential measuring device renowned for its accuracy. The image reveals two sets of jaws on the left side, each serving a distinct purpose: the lower jaws are employed for external measurements while the upper jaws facilitate internal measurements. To determine the desired distance, these movable jaws can be adjusted using the wheel located at the center-left section of the calipers. The oval area positioned nearby contains a remarkable feature known as the Vernier scale, which greatly enhances measurement precision. This ingenious scale enables users to obtain readings with increased accuracy by aligning it with corresponding markings on both centimeters (lower scale) and inches (upper scale). Additionally, protruding from the far right is a moveable rod that allows depth measurements to be effortlessly obtained. Constructed from sturdy steel and exuding an air of technological sophistication, this single apparatus embodies engineering excellence. Its presence in scientific laboratories and engineering workshops signifies its importance as an indispensable tool for professionals across various disciplines. Captured by Science Photo Library, this visually striking photograph beautifully captures not only the physical attributes but also highlights how technology intertwines seamlessly with precise measurement techniques in our modern world.
