LX4000 POLYGRAPH SYSTEM
The LX4000 Computerized 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.

However, IP cameras may experience audio/video lag or other undesirable behavior. The use of a directly-attached camera is highly recommended.
- External Microphone may be required for recording audio, depending upon host computer's configuration (e.g. no built-in microphone), examine / examinee location, ambient noise, etc
* Additional resources may be required for certain video devices. Always consult the documentation for any selected video device to ensure the host computer meets the stated system requirements.
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.
