Measurement of videoXtens systems in combination with a ZwickRoell temperature chamber is unbeatably accurate. Example: The videoXtens 2-150 HP meets the strict requirements for determining the tensile modulus in accordance with ISO 527-1 Annex C, even under temperature conditions. Why this is the case: ZwickRoell video extensometers and temperature chambers have been adapted to perform optimally with each other. Temperature controland air distribution in the temperature chamber are optimized in such a way that the videoXtens resolution is only minimally affected, even at different temperature conditions.The entire system is closed: videoXtens is connected to the temperature chamber through a tunnel. Influences due to air turbulence are thereby also minimized outside of the temperature chamber.
