We analyze the determination of the dielectric constant of macroscopic solid samples in a nondestructive way from measurements of the capacitance between a pointer electrode and the sample's surface. We assembled an experimental device and found that an accuracy of 1% or better can be attained with common laboratory instrumentation. ©2009 American Institute of Physics
