Overview

ADInstruments Bio Amps are galvanically isolated, high-performance differential biological potential amplifiers optimized to measure a wide variety of biological signals such as ECG / EKG, EMG, EOG, and EEG recordings. In conjunction with a PowerLab and LabChart, a wide range of filters are available for processing biosignals.

Our Single, Dual, Quad and Octal Bio Amps are supplied with Bio Amp Connection Cables and Lead Wires making them suitable and safe for both human and animal connection. An audio output is also available to help monitor signals.  

Accessories suitable for use with Bio Amps include:

ADInstruments signal conditioners only function with PowerLab data acquisition units and therefore are not suitable for use with other data acquisition systems.
