Pulse Plethysmograph (piezo crystal) with DIN connector


SKU: PT-104 Category:


The PT-104 plethysmograph with DIN connector for use with iWorx Computer Interfaces is a sensitive, rugged, non-magnetic sensor, ideal for classroom use. Its small in size and plugs directly into any recorder input, requiring no auxiliary power. 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.
