M Cubed Electronix company sells a very accurate Inductance-Capacitance-Resistor
"The M3 DIGITAL LCRZ Meter is a multi-frequency impedance measuring
instrument capable of measuring resistance, capacitance, inductance, or
transformer parameters from 1 milliOhm to 100 MegOhms. The M3 DIGITAL
LCR meter has a basic accuracy of 0.2%, has 10 user selectable test frequencies
and 6 impedance ranges." From their web site at www.m3electronix.com/lcr.html.
