140+ List of Measuring Instruments and Their Uses

Dear Aspirants, In this article I provide a complete list of  Measuring instruments and their uses which we use in our daily life which are very useful for us. Different Instrument has different work properties.

In most of the Competitive examinations like Railway NTPC, JE, ALP, Group D, SSC CGL, CHSL, Banking, FCI, State PSU, etc., science is a major part of General Knowledge. Most questions arise in the examination from Unit and Measurement, Chemical Formulas, Inventions and Discoveries, Important Minerals & Ores, Various Branches of science/Study of Different fields, etc. which are helpful for all students and Aspirants for all competitive examinations like Railway NTPC, JE, Group-D, SSC, Banking, and state PSU.
