Note:Teaching Kits or IX-214 or IX-TA-220 use the PT-104 instead.

The PT-100 plethysmograph with BNC connector is a sensitive, rugged, non-magnetic sensor, ideal for classroom use. They're small in size and plug directly into any recorder input, requiring no auxiliary power. When used as a pulse sensor, PT-100s produce 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. Because the PT-100 is self-powered, it does not require a conditioning amplifier.
