Both accuracy and precision (reproducibility) are substantially influenced by changes in temperature. The Verisurf Coefficient of Thermal Expansion mobile app makes it easy to quickly determine the effect temperature has on the length of a given material.

Using the app is simple. Select any material from the pull-down menu to load its CTE into the calculator, then enter the material length, material temperature, and a reference temperature. The app automatically displays the change in unit length and in total length caused by the increase or decrease in material temperature from the reference temperature.
