PLUGSYS Biopotential Amplifier Module (BPA)
Price on Request
Used to amplify ECGA, EMGA, EEGA and BPA biopotentials
The Biopotential Amplifier Module (BPA) is used to amplify ECGA, EMGA, EEGA and BPA 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.
The input cable (73.3357) is a binder connector to 3 x 1.5 mm male Touchproof connectors (red, yellow, black). Binder connector cable end shielded length 1.7 m to Touchproof connector end 30 cm unshielded length. Total length 2 m.
