The PER 2000 was engineered after the Papimi became banned in the U.S. They designed it smaller, safer and more affordable than the Greek predecessor (Papimi).

Is there any other device like the P.E.R. 2000?
There are many different devices on the market today. The majority are “only” magnetic field therapy devices (PEMF) and do not generate the specific resonance frequencies, effective to biological cells, comparable to the PER 2000. Those resonance frequencies can only be generated in a gas (regular air) plasma chamber, using a high voltage sparkover. Other devices use solid semi-conductors that can only generate one peak. Thus these devices are only simple magneto therapy devices (PEMF) and definitely not CRTs.
The PER 2000 is not a magneto therapy device!
There is only one CRT dvice related to the PER 2000, produced in Greece, the PAP IMI. It has the size of a fridge and the weight is app. 100 Kg and was designed over 20 years ago! The PER 2000 was developed by two experts that had been responsible for maintenance and repair of this greek device in the US for 9 years. The goal for the PER 2000 was to design a small and light weight, mobile device using state of the art technology and electronics. The result is remarkable.
