The ProComp Infiniti is an 8 channel, multi-modality encoder with the power needed for real-time, computerized biofeedback and neurofeedback data acquisition in any clinical or educational setting.

This device has 8 protected pin sensor inputs with two channels sampled at 2048 sampes per second and six channels sampled at 256 samples per second.

The ProComp Infiniti encoder is able to render a wide and comprehensive range of objective Physiological signs used in clinical observation and biofeedback.

The first two sensor channels of the Infiniti encoder provide ultimate signal fidelity (2048 samples per second) for viewing raw EEG, EMG and EKG signals. The remaining six channels (256 samples/sec) can be used with any combination of sensors, including EEG, EKG, RMS EMG, skin conductance, heart rate, blood volume pulse, respiration, goniometry, force, and voltage input.

ProComp Infiniti offers internal, user-activated calibration to ensure that you can always obtain the highest quality signal, without the costly downtime associated with factory re-calibration.

In short, the ProComp Infiniti covers the full range of objective physiological signals used in clinical observation and biofeedback.

Housed in an ergonomically designed case and requiring only a USB port, ProComp Infiniti can be used with any IBM-compatible laptop or desktop PC. Whats more, ProComp Infiniti can capture data in real time by connecting directly to the PC via fiber-optic cable, or it can store data on a Compact Flash memory card for uploading later to the PC.

Infiniti Software

The Infiniti software is created in a modular fashion to ensure you get only what you need and do not fill your computers memory with unwanted software. The Developer Tools will allow for high end users to create their own screens, scripts and channel sets. This ultimately provides the customer with the most variety under one system.

The ProComp Infiniti hardware comes with the Infiniti Software and your choice of either the Electroencephalography (EEG) Suite or Physiology Suite.

When ordering, please specify which Suite you want to include. The second Suite may also be purchased for an additional $ 250.00. If using our shopping cart, just type into the comments box your Suite preference. When ordering by phone, please specify.

NOTE: ProComp 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.
