Computerized Polygraph System Machine
Price: P595,000.00
The computerized polygraph system consists of sensors, main unit, microprocessor, and test software.
Sensor: it refers to the components which transfer the tested person’s physiological parameters such as GSR, respiration and radioactivity to the analog signals
Main Unit: it refers to the device which converts the analog signals measured by each sensor to digital signals, and then send them to microprocessor.
Microprocessor: The device processes the test prepare, test control, and data analysis.
Test Software: the executable files stored on microprocessor. It could process the edition, display, print, storage, and analysis and automatic judgment.
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.
PG-7 Polygraph system
Designed as a basic testing system, PG-7 Polygraph system can be record four parameters. It’s simple and practical, easy to operate and with stable performance.
PG-7 Sensor channel
GSR (Galvanic Skin Response), Breast respiration, Abdomen respiration and Finger pulse
