Digital Physiograph(P800)

Overview

P800 2011 is a digital physiograph which applies digital technologies to each biosignal amplifier module and measures various biosignals like electrical and physical signals through 8-channel biosignal amplifier modules.
(Measurable biosignal: ECG, EMG, EEG, EOG, pressure, force (grip), PPG, EDR, sound, etc)

It digitizes all amplifier module and adapts 24bit ADC to sharply improve accuracy and degree of precision. Also, the product facilitates easy measurement by controlling its hardware through P800 software (P800 RMSW).

The system consists of P800 body, sensors and PC monitoring software(P800 RMSW). The P800 body and monitoring PC are connected by USB cables.
