A polygraph machine records the body’s involuntary responses to an examiner’s questions in order to ascertain deceptive behavior. The test measures physiological data from three or more systems of the human body-generally the respiratory, cardiovascular, and sweat gland systems-but not the voice.

Polygraph testing is mainly done for law enforcement, judicial and the private business sector purposes.

The best instrument delivers the best results which is why we only offer polygraph solutions designed to medical grade standards.
