7700 Series Isolated/Defibrillation Protected ECG and General Purpose Probes


  • 3 Lead connection with an array of electrodes
  • Provides galvanic isolation to the signal conditioner
  • Protects signal conditioner from defibrillator discharges
  • Built-in “Zero” and “Cal” buttons for ease in calibrating channel

The Isolated Defibrillation Protected ECG and General Purpose Probes (13-7758-IDP and 13-7759-IDP) are designed to conduct pre-clinical studies and investigation (clinical research) of physiological processes.  The probes are suitable for intra cardiac, surface electrodes, Action Potential measurements or other applications where isolation is needed.  Additionally, built-in Zero and Cal buttons provide for a simple, accurate calibration process.  The probes interface  specifically to the 7700 Series Universal Signal Conditioner, model 13-7715-58 and Universal XE model 13-7715-59.
