Product Description
General Determined Parameters
- GRS (Galvanic Skin Response) Skin conductance changes along with the variety of skin sweet gland’s activity. The tested person’s sympathetic nerve system activity can be reflected by the change of GSR.
- Cardio-activity: The polygraph determines cardio activity by indirect measurement, .ie. by some special methods putted on the outside of body, it makes the blood preasure pass through some intermedium such as organize and skin and them be transferred to the sense organ of the measuring instrument. The psychological behavior is reflected by he change of cardio activity which includes average flood pressure, blood volume and pulse.
- Respiration: it refers to the changes of breath process parameters including breath frequency, the time ratio of the breath out and breath in, which is caused by the change of physiology behavior. It includes upper and lower chest assembly, i.e. breast and abdomen reparation.
- Pulse: It refers to the elastic distortion of artery wall due to the extruded blood during the periodic beat of heart.
