The PT-104 plethysmograph with DIN connector for use with iWorx Computer Interfaces is a sensitive, rugged, non-magnetic sensor, ideal for classroom use. When used as a pulse sensor, the PT-104 produces a signal from which rates and relative pressure information can be computed. The real-time integral of this signal is identical to volume pulse signals recorded with more expensive infrared pulse plethysmographs. Applications include measurement of peripheral pressure pulses and Korotkoff sounds and small animal respiratory activity.
