- The Purpose of Video Extensometer is to optically measure the elongation on application of longitudinal tensile force on the test specimen.
- Markers, especially dots, lines or pre designed templates are used to track elongation in real time.
- The markers used should be in contrast with the color of the test specimen.
Advantages over contact type Extensometer
- More accurate results as there is no mechanical influence on the specimen during the test due to the non-contacting camera system.
- Knife edge Slippage errors are omitted.
- Knife edge damage errors are omitted.
- Auto Gauge Length Detection - Consistent results as the human error is eliminated while marking the Gauge length.
- No moving parts - hence, extremely low maintenance costs.
- No possibility of damage due to rupture shocks and jerks - hence, no wear and tear of the Video Extensometer
- Gives you Elongation results upto the sample rupture.
- Extremely easy to use for untrained operators.
