Used EEG-Z Impedance Sensor - SA9305Z

The Procomp Infiniti EEG-Z Impedance Sensor(T9305Z) with DIN (T8740) can be used for both Neurofeedback training and also works as an impedance meter. The EEG-Z works with the Flexcomp, Procomp Infiniti,Procomp2 or Procomp5 biofeedback / neurofeedback systems.

Enhance the quality of your ProComp EEG recordings with high quality, low impedance electrode connections to your clients. EEG leads not included.

• Fast, in-line impedance checking for the ProComp Infiniti. No need to plug and unplug the electrodes from the sensor! The impedance check is performed directly inside the sensor for all three leads at the same time.
• Windows based E-Z Connect software.
• User-adjustable sensitivity range settings for optimal customization.
• Easy-to-read color coded quick reference diagram.
• Real values for electrode to electrode impedance and single electrode identification.
• Optionally displays the total impedance value, which includes both the resistive and reactive elements to give the most precise readings.
• Real values for electrode to electrode impedance and single electrode identification. Optionally displays the total impedance value, which includes both the resistive and reactive elements to give the most precise readings.

Now you can be certain every time, that you have sufficiently prepped the electrode sites-without having to disconnect the electrodes.

Software allows you to define your own sensitivity ranges for impedance checking. The easy-to-read, color-coded graphical display allows you to quickly see when an electrode is not well placed. Green numbers indicate a good placement while yellow and red numbers show the electrodes that have a bad contact.

For the first 10 seconds after it is turned on, the EEG-Z sensor checks the impedance on all three leads. Then it automatically switches to a regular EEG reading mode, and youre ready to record.
