The GP8e 6 channel biofeedback system is an excellent way to add biofeedback to your practice or research. The low start up cost makes the system attractive to budget conscious individuals.


Physioamps configured by software for EMG, ECG. EEG

Sensor cables add finger pulse, respiration, skin conductance/resistance, and temperature

  • NO BATTERIES -- Power is supplied from USB by an isolation module. This reduces downtime and service problems.
  • RELIABLE CABLES – Medical standard 1.5mm pin to snap leads are used for electrode connections and are available from many suppliers.
  • NEW TECHNOLOGY – This gives cleaner signals, more reliability, and lower cost in a compact, rugged enclosure.
  • SOFTWARE – General purpose signal monitoring and recording applications are included. The included software is supported on Windows 7, 8, and 10. Third party software is available from several suppliers. We provide drivers and support for software developers.
  • COMPACT DESIGN - A general purpose physiological signal monitor in a case the size of a pack of playing cards. Add a small computer and you have a system in your pocket.
  • CONNECTION TEST – A built-in test monitors electrode connections.
