A seismograph is also sensitive to changes in temperature so many instruments are constructed from low expansion materials such as nonmagnetic invar.

In 1922, the U.S. Coast and Geodetic Survey began two years of painstaking measurement of the baseline using the recently available invar tapes.

Invar behavior is pretty subtle, requiring a very special condition for the electrons in the metal that is usually tuned by precise control of chemical composition.

This pattern, built a couple of meters wide out of temperature-invariant steel invar, was used to keep the trains running on time in France before World War I.

Historically, distances were measured using a variety of means, such as with chains having links of a known length, for instance a Gunter's chain, or measuring tapes made of steel or invar.

- Invar, also known generically as FeNi36 (64FeNi in the US), is a nickelu2013iron alloy notable for its uniquely low coefficient of thermal expansion (CTE or u03B1). The name Invar comes from the word invariable, referring to its relative lack of expansion or contraction with temperature changes.
- Special alloy related to beryllium and used for watch parts because it is not magnetic and resists rust.
- Invar is a special nickel-iron alloy that resists thermal expansion.
- An invar shadow mask is a premium feature available on select television models that is designed to give the picture more brightness and a crisper appearance.
