WELCOME    TO    AVTALION    POLYGRAPH   

Using the latest in 24 Bit Analog to Digital conversion technology, the CPS II system provides new hardware, new transducers and new CPS II software, for the most versatile, technologically advanced, and user friendly polygraph system available. The CPS II scoring algorithm is the only algorithm validated using standard scientific methods. The small, lightweight CPS II is powered directly from the USB port connector on your computer. The Eight Channel CPS II is equipped the following channels and transducers.

- Two Respiration channels, Thoracic and Abdominal, using Piezo Electric Strain Gauge transducers for high quality signals.
- One Cardio Channel with Universal Arm Cuff records both blood pressure and pulse rate.
- One skin conductance/ Resistance Channel using Silver/ Silver Chloride disposable or fixed electrodes.
- One Plethysmograph Channel for recording blood volume in the extremities.
-One Activity Channel using highly sensitive Seat Pad Piezo Strain Gauge sensors.
- One Skin Potential/ Auxiliary Channel that records and measures skin potential as an alternative to GSR, when the subject shows little GSR activity.
- One Voice Marking Channel with two external microphones for marking the precise moment of question onset/offset and answer onset.
