Inline Rapid Impedance Spectroscopy (iRIS) is a method of quickly measuring impedance measurements over a broad range of simultaneous frequencies. Montana Technological University (MTech) has been sponsored by Dynexus Technology to enhance the iRIS system capabilities, including an improvement in the overall measurement resolution. The baseline iRIS system has a stated resolution of $\pm 0.01\mathrm{m}\Omega$ and a previously-developed resolution enhancement kit demonstrated an improvement down to $\pm 0.01\mathrm{m}\Omega$. Continued research with the enhancement kit has shown that the iRIS system can potentially achieve resolutions better than $\pm 5\ \mu \Omega$. An overview of this new approach along with measurement results that demonstrate very high resolution is presented.
