IMPORTANT SCIENTIFIC INSTRUMENTS & THEIR USES

Hello Readers!
In this post, we are sharing List of few important Scientific Instruments and their uses. These instruments are frequently asked in different competitive exams like Railways, SSC, Banking, PSUs etc. We hope this will be very much helpful for your upcoming competitive exams. If you find any Instrument which is not there please comment below, we will update this post with those instruments.
