A radio frequency method has been used to measure the dielectric constant $K$ of dry air free from C${\mathrm{O}}_{2}$, the value obtained being 1.0005893 for standard conditions of temperature and pressure. The probable error in $K\ensuremath{-}1$ due to accidental variations is 0.34 percent. The method is a modification of the usual heterodyne beat arrangment. Capacity changes produced when the pressure in the test condenser is changed are compensated by a suitable condenser in parallel. The… CONTINUE READING
