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.
