ABSTRACT:
Two embodiments of a device and method are disclosed for providing a correction factor for the velocity of electromagnetic radiation in air. The devices include a pressure-responsive vessel having a predetermined quantity of gas enclosed therein and means for sensing the size of the enclosed volume to provide a measurement of the correction factor. Means are also disclosed for employing a humidity responsive device for moving a scale so that the correction factor is also made responsive to the humidity.
