Links

The high-performance, differential biological potential amplifiers known as ADInstruments Bio Amps are galvanically isolated and designed to assess a wide range of biological signals, including ECG/EKG, EMG, EOG, and EEG recordings.

A number of filters, including the following, are available for processing biosignals from many study fields in conjunction with a PowerLab and LabChart:

Autonomic and sympathetic nervous system function
Cardiovascular disease and myocardial dysfunction
Muscle activation and fatigue
Evoked responses and stimulation
Heart rate variability/arrhythmia

Single, Duo, Quad, and Octal Bio Amps are equipped with Lead Wires and Bio Amp Connecting Cables, making them acceptable and secure for connecting to both people and animals. Also accessible for signal monitoring is an audio output.

The following items are compatible with Bio Amps:

Reusable ECG Electrodes
Chest ECG Electrodes (suction)
EEG Flat Electrodes
ECG Lead Switch Box
EEG Cap Systems
Adapter Packs
Octal Bio Amp Linking Cables

Signal conditioners from ADInstruments are incompatible with other data acquisition systems and only work with PowerLab data acquisition devices.
