LX4000 POLYGRAPH DAS UPGRADE
Model
LXUPGRD
DESCRIPTION
The LX4000 computer polygraph system records, stores, and analyzes physiological changes during a polygraph examination. The LX4000 system combines conventional polygraph procedure with a sophisticated state of the art computer. Results are derived from the following traditional physiological parameters:
- Pneumo - Two Respiration Input Channels
- EDA - Galvanic Skin Response
- Cardio - Blood Volume/Pulse Rate
We currently offer a Plethysmograph (PLE) Model 76599LX to measure finger pulse and blood volume, Activity Sensor Model 76879S to measure any movement by the subject to help identify countermeasures. A total of seven channels can be recorded at one time.
Charts are recorded in much the same manner as conventional polygraph instrumentation with a smooth scrolling display moving from right to left. The tracings recorded are in real-time and are truly rectilinear, so charts can be easily interpreted. See polygraph software page for a sample of the tracings. The system can be operated using a mouse / pointing device or the keyboard.
