PLUGSYS Biopotential Amplifier Module (BPA)
Used to amplify ECG, EMG, EEC, and ENG biopotentials
The Biopotential Amplifier Module (BPA) is used to amplify ECG, EMG, EEG, ENG biopotentials in the PLUGSYS system. It can also be used with strain gauge transducers.
The BPA amplifier module is a non-isolated amplifier. It is designed specifically for physiological and pharmacological animal experiments.
