LX4000 POLYGRAPH DAS UPGRADE

Model LXUPGRD

LX4000 Polygraph DAS Upgrade
 
 

DETAILS

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:

  • Pneumo - Two Respiration Input Channels
  • EDA - Galvanic Skin Response
  • Cardio - Blood Volume/Pulse Rate

We currently offer a Plethysmograph (PPG) Model 76604A-5L with an adaptor (Model 76604ADP) to measure finger pulse and blood volume. 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.

FEATURES

  • Our new USB Interface enables the LX4000 to communicate with virtually any Windows based PC computer.
  • The LX4000 is capable of simultaneously displaying and recording seven input signals
  • The LX4000 is Small and Compact, making transporting it even easier.
  • The Redesigned EDA Circuit has a greater operating range, increased sensitivity and subject isolation.
