Try Campbell Scientific in Logan UT. They have TDR (time-domain
reflectometry) equipment just suited for the purpose. Also a bit pricey,
but you don't need a radioactive materials license to use it.
I designed my own TDR probes and system around a Tektronix 1502C TDR meter
for my PhD work; the probes ended up costing me about $5 each.
