CAMBRIDGE INSTRUMENTS MIRROR GALVANOMETER, 1950's

Mirror Galvanometer standard design of the period. These instrument were becoming obsolete as Oscilloscopes were taking over,and have in this form have fallen out of use. Mirror galvanometer systems are now used as beam positioning elements in laser optical systems.

Your comments:

• I remember using these, or similar, instruments in the late 1950's in the measurement of the output of Platinum/Platinum Rhodium thermocouples to measure temperatures and temperature differences in a specialised apparatus which involved raising specimen temperatures approximately linearly from room temperature up to about 500c
