The SleepSense Double Loop Piezo Crystal Respiratory Effort Sensor (#1387) with safety DIN connectors can be applied with any elastic-velcro band.

Warranty: 1 Year - Free of Defects in Materials and Quality Workmanship.

Using the piezo-electric crystal, the respiration effort sensor converts chest or abdominal respiration movement to a small analog voltage that provides a clear, reliable indication of respiration waveforms.

This device is for diagnostic purposes only and not for use as an apnea monitor.
