Polygraphs/Lie Detection Test: A polygraph is an instrument that records continuously, visually, permanently, and simultaneously, changes in cardiovascular, respiratory, and electro dermal patterns. The test makes a written recording of the changes in your respiration, pulse rate, relative blood pressure, and psycho galvanic skin responses by placing four attachments on your person. Our polygraph instruments are modern and computerized. Certified examiners who have extensive experience administer our tests. The tests can be given at your location for convenience.
