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.

      The Gp8 6 channel device comes with Physio Application software, but is also compatible with Bioexplorer and Alive.

    Where do I download the native GP8 software from J^J physio, please? I purchased a device in February and it suddently gave up, not detecting any clean beats with Alive. Desperate to fix it, and wonder whether with its native software any checks/calibration can be undertaken, to save me the long and painful shipping back and forth?
    Thank you very much for your help with this.

      The package comes with snap cables and you can use snap style EEG sensors. You can also order silver or gold EEG electrodes for use with the unit. It does not come with EEG leads.

    Buongiorno , posso vedere la temperatura la conduttura cutanea e l hrv contemporaneamente?
    E posso vederli in tempo reale o è in ritardo di alcuni secondi il segnale?

      I have translated for others as well - Question - Hello, can I see the temperature, the skin duct and the hrv simultaneously? And can I see them in real time or is the signal delayed by a few seconds?

      Yes you can see multiple modalities at once using the GP8

    Hello. Could you please tell me whether this unit stores the data itself or whether the data is downloaded to a computer when the data is being acquired by the sensors. If so, can the unit be powered by a USB power pack so that it is a portable device that can store data to be downloaded later on when connected to a computer. Many thanks, Alan.

      This unit has to be connected to a computer at all times during use.

      The J&J hardware did at one point work with the LENS. I am not sure if that is still the case. From what I understand they have new hardware.

      Unfortunately, there is little documentation at this time. This is a newer device and is best suited for non-clinical use.
