Strain Gage Sensitivity (with a good instrument)

One microstrain is one part-per-million.  This is the equivalent of resolving 1 cm out of 10 kilometers!  A strain gage can easily resolve 1 microstrain, as long as a quality instrument is utilized.  In this video, Anton Chitty demonstrates the sensitivity of a strain gage that is possible with a good quality instrument, such as the Micro-Measurements P3 Strain Indicator and Recorder.
