There are some articles floating around on the web about a Defelsco eddy current measuring device developed and sold in conjunction with the SGIA in about '97.
Defelsko don't list anything for screen printing other than the Positector 6000 and the Positector DFT (sold by several mesh suppliers for EOM measurement), but none of these have the range of measurement required for common off-contact distances.
Does anyone know where or even if this or an alternative instrument is available?
Edit: Thought a pic of the unit being used might be useful and prod someones memory.
