I have found several excellent E meters, of Russian Manufacture. They are fully digital, and well constructed. They are bio feedback devices used in auditing and clearing people. Below are several models of the meters, with some pictures.

ICAUSE will distribute these meters in the US and Europe as soon as the logistics can be worked out. Currently the delivery time is about a month.

FREEDOM METER
