Bio Amps

$995.00-$2,295.00 USD

Electrically isolated, high-performance differential biological amplifiers optimized for the measurement of a variety of biological signals such as ECG, EMG and EEG.

Add to Cart Request Demo

Overview

ADInstruments Bio Amps are galvanically or electrically isolated, high-performance differential biological amplifiers optimized for the measurement of a wide variety of biological signals such as ECG, EMG and EEG recordings. In conjunction with a PowerLab and LabChart, a wide range of appropriate filters are available. Single, Dual and Octal Bio Amps are supplied with Bio Amp Connection Cables and Lead Wires making them suitable for human connection. An audio output is also available to help monitor signals. Micro-Hook Electrodes are included with the Animal Bio Amp. 

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.
