Today, instruments can be found in laboratories, refineries, factories and vehicles, as well as in everyday household use. Different types of instruments are required for the measurement of different physicals quantities like temperature , pressure,flow,level, density ,viscosity ,humidity and concentration etc. Electronics plays an important role in these instruments. Sometimes ,these quantities are very small  e.g to determine the mass of electron and some times these quantities  are very large e.g. to determine the mass of e...
