The ProComp5 Infiniti measures up to five channels of your choice for both neurofeedback and biofeedback training.

The Procomp5 with v6.0 Infiniti software is a versatile five channel system. The first two sensor channels provide ultimate signal fidelity for viewing raw EEG, SEMG, EKG and HR/BVP signals (2048 samples per second), while the remaining three channels sample data at 256 samples/second for slower signals such as respiration, temperature, GSR, force, etc.

ProComp5 Infiniti is housed in an ergonomic case and requires only a USB port to connect to any PC. ProComp5 Infiniti has the identical inputs as ProComp Infiniti 8 channel system, but omits the last 3 channels.

Not only can ProComp5 Infiniti capture data in real time by connecting directly to the PC via its fiber-optic cable, but it can also store data on an optional Compact Flash memory card for uploading later to the PC, or use optional long-range compact flash module telemetry.

Unlike competitive equipment, all channels can be used with any combination of sensors, including EEG, EKG, RMS SEMG, Skin Conductance, Heart Rate, Blood Volume Pulse, Respiration, Goniometer, Force, Inclinometer, Torsiometer and Voltage Input.

The ProComp5 hardware comes with the BioGraph Infiniti Software and your choice of either the 360 Suite or Rehab Suite.

    thank you for your answer. I would like to use Procomp 5 for research. So I will be needing to present several visual stimuli to a participant on a computer on which my experimental task is running. parallel to this I would like to record heart beat and skin conductance responses of the participant. therefore, I need to have a marker on the SCR signal when the visual stimulus was presented.
    I would like to know if this is possible with Procomp 5. Thanks!

      The Procomp 5 (Infiniti software) allows you to mark events. There are several "hot keys" that can be set up to have more than one marker if you choose.

    Hello there. is triggering possible with Procomp5? if it is so, how many triggers?

      Triggers can be created in the software. Are you looking to control an external device? If so this would require some customizing of the software. There are threshold triggers that activate sound or animations in the software.

    I have 2 questions:

    1) Does the machine come with sensors or they need to be bought additionally?

    2) Do you require any special requirements when someone wants to buy the machine or anyone can buy it? (ie. does the person need to be a medical staff or no)

    Please advise on the above and thank you,

      The Procomp 5 does not come with sensors. They are purchased separately. You must be a clinician or working with a licensed clinician to use this device.

NOTE: ProComp5 Infiniti and its Sensor Heads and sensors are sensitive electronic instruments and should be handled as such. Be especially careful to avoid both pulling on the sensor cables and leads or getting moisture and gel on the sensor snaps. If necessary, wipe the surface with a damp cloth or use a moistened Q-tip to remove gel from inside the sensor snaps. Wipe with a dry cloth.
