Polygraph Australia

We are using the latest generation computerised polygraph instrument that makes a continuous recording of autonomous responses that are associated with respiration, electrodermal activity and cardiovascular functioning. In addition to this we are also using a Photoelectric Plethysmograph that measures relative changes in blood volume. Research shows that the use of the Photoelectric Plethysmograph increases the reliability of the test
