IR Plethysmograph - Velcro Strap
The MLT1020PPG Plethysmograph is an infrared photoelectric sensor used to record changes in pulsatile blood flow from the finger, toe or forehead. The Plethysmograph operates by recording changes in blood volume as the arterial pulse expands and contracts the microvasculature. The Plethysmograph can be plugged directly into a PowerLab Pod port, or any ADInstruments Bridge Amp Front-end (amplifier).
