Biopac Student Lab Accessory
The SS4LA photoplethysmogram (PPG) transducer operates with the data acquisition unit to record the blood volume pulse waveform via optical methods.
The SS4LA consists of a matched infrared emitter and photo diode detector, which transmits changes in infrared reflectance resulting from varying blood flow. Blood is highly reflective of near infrared light wavelengths, due to the heme subunit of hemoglobin. When the PPG transducer is placed on the skin, in proximity to capillaries, the reflectance of the infrared light from the emitter to the detector will change in accordance to capillary blood volume. The PPG waveform peaks when capillary blood volume is maximized.

Attach to a finger via the Velcro strap or tape to other body locations. The ergonomic housing improves contact with the subject and reduces movement artifact. Includes shielded 2-meter cable.
