Features
Enhanced PPG Sensitivity
The LX7 features improved detection of subtle, rapid changes in pulse blood volume via the photoelectric plethysmograph (PPG) sensor, delivering more reliable cardiovascular readings across a broader selection of examinees.
New ECG channel for Pulse Arrival Time (PAT) measurement
Calculates the time between the ECG pulse and PPG waveform providing a time measurement that is directly correlated to blood pressure. Supports research and further development of the PAT measurement as an eventual replacement for the cardio measurement. Research has found that PAT is as effective as the cardiograph for discriminating between truthful and deceptive people in a polygraph test.
Expansion port to support future sensor development
Newly designed sensors already in development. Coming soon!
Modernized enclosure design
Maintaining high quality reliable connectors, the LX7 employs a curved design that improves cable management and organization for a cleaner workspace. Enclosure is built with polycarbonate blend for superior toughness, durability, impact resistance and heat resistance.
