EVC-B Polygraph systems. The 4th revolution in the evolution of Polygraphy.
Problematic and unreliable pneumograph tubes are GONE.
EVC-B replaces bulky pneumographs with synchronised biometric and cognitive measurement — delivering cleaner data and greater examiner control.
Uncomfortable inflatable BP arm cuff is GONE.
What makes EVC-B really different?
