The SleepSense Multi-Press Pressure Transducer (# 14840-Kit) provides AC flow and adjustable snore sensitivities through digital control over five levels. 

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

This sensor will automatically turn itself on when breathing is detected and automatically turn off when breathing is not detected for five minutes. This product has calibrated DC pressure output as well as AC flow and snore channels for optimal use in any sleep lab. When used as a DC transducer, replacing the batteries will automatically set the module back to zero.

The Multi-Press is designed to monitor respiration through air pressure sensing in non "life supporting" applications, such as sleep studies. Output from the sensor enables pressure values to be recorded onto polygraph, EEG or similar physiological recorders. The sensor is powered by two AA batteries, which are included.
