We compensate for thermal expansion. The standard temperature things are measured at is 68F/20C. So if it's 72 degrees we'll compensate it back to 68 in software for the material we're measuring. We use scale bars of known length and similar material type to verify scale. (I run laser trackers and laser radars.)

For measurement equipment that's stationary, like CMMs, you just control the environment.
