Digital Physiograph(P400)

Overview

P400 is a digital physiograph which precisely measures various biosignals including electrical and physical signals and transmits to the PC for record and analysis.
(Measurable biosignal: ECG, EMG, EEG, EOG, pressure, force (grip), PPG, EDR, etc)

P400 consists of the biosignal measuring module which simultaneously measures analog signals up to 4 channels and the base module which converts them to digital signal and transmits to the PC. Also, modules are easily assembled/separated with plug-in type to form an optimal environment for the measurement.

P400 may observe various biosignals depending on time through PC monitoring, perform experiments and researches on the purpose (providing examples) and maximize effects through audio-visual education.
