The SleepSense Multi-Press provides you with AC flow and snore sensitivities adjustable through digital control over 5 levels. This sensor will automatically turn itself on when breathing is detected and automatically turn off when breathing is not detected for 5 minutes. The Multi-Press has calibrated DC pressure output as well as AC flow and snore channels for optimal use in any sleep lab. When used as DC transducer, replacing the batteries will automatically set the module back to zero.
