In 1580-1637, Frenchman Pierre Vernier invented the vernier graduation scheme. The vernier scale was named after him because of his tremendous invention. Nonius and vernier were similar in Germany even though the invention of the vernier scale was made by French Pierre Vernier. Nunes scale consisted of equally divided arcs, each of the arcs had one less division than the one that was outside it. He invented the “ Nunes Scale” which improved and modified the accuracy of inclinometers used by astronomers and astrologers. Nunes made a remarkable invention that was then used for further modification. Nonius derived from a Portuguese is known as Pedro Nunes. The word Nonius came from the German language and most Japanese words are derived from the German language. Nogisu is a Japanese word but it doesn’t really sound Japanese. Nogisu has derived from another word known as “ Nonius” which means the division of the main scale into smaller increments. This was originally made of horn, bone, or mammoth but later it was made with glass, wood, or iron. This measuring instrument consisted of two jaws and sliding scales. The first traces of caliper lead back to the Chinese Yin era where a sliding measuring instrument was used. We may mistakenly write the wrong history. Advertisementsĭisclaimer: The caliper history that we post on this page may be debatable. Even, they have transformed into a digital measuring instrument that can transfer the readings wirelessly. Starting from the old-style without vernier scale, now, it becomes vernier scaled. Each of them has their own argumentation. Some say it was from East, some say it was from West. The vernier caliper and other types of caliper that we use today have passed a long story before.
