LX4000 POLYGRAPH SYSTEM
Model LX4000-S

LX4000 Polygraph System

DESCRIPTION

The LX4000 Computerized Polygraph System records, stores, and analyzes physiological changes during a polygraph examination. The LX4000 system combines conventional polygraph procedure with sophisticated state of the art technology. Results are derived from the following traditional physiological parameters:

We currently offer a Plethysmograph (PPG) Model 76604A-5L with an adaptor (Model 76604ADP) 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.

There are limited quantities of LX4000 units available; we recommend considering the LX5000 or LX6 systems instead. Visit our Polygraph comparison sheet for more information about each of our systems.
