Nox Self-Applied Somnography™

PSG sleep study at home

The Nox Self-Applied Somnography* (Nox SAS) collects relevant sleep data comparable to traditional PSG while being self-applied by the patient. The Nox SAS has been employed in more than 6,000 research studies worldwide.
*The Nox Self-Applied Somnography is for research purposes only.

Increased Robustness
and Supreme Signal Quality

The extremely high sampling rate of 256 kHz, continuous impedance control, and automatic reference adjustment all build a foundation for minimizing lost studies due to electrodes falling off or unsatisfactory signal quality.

Wireless Oximeter

Wireless Sensors
Unlimited Possibilities
