HT Optical Extensometer

HT is a professional optical extensometer for high-temperature applications suitable for temperatures ranging from ambient temperature up to 1400 °C.

The HT uses the same user-friendly DIC software interface as the ONE series, which allows you to focus on the experiment and data acquisition. Besides materials testing at elevated temperatures, the HT is suitable for any application requiring a precise and accurate optical extensometer with a small field of view.
