Powerful Customizable Reporting.

Need simplicity? Then start with our standard report template and change the order if required. Or select the data you want in each table/graph and display it in the order you want. You can even add your own branding in the header.

Need more? Then use our custom report builder and make you own design with total freedom. The possibilities are nearly endless.

The future of PSG is here.

The future is here – our most powerful and flexible sleep diagnostic system. The SOMNOscreen® HD is a new generation of PSG with 55 channels (10 internal, 28 external, 17 EXG via the headbox) which can be upgraded to 70 channels, they are recorded at a resolution of up to 4 kHz per channel. Excellent signal quality goes without saying.

With intelligent connect, the new montage free sensor recognition, you can connect any sensor to any slot and also change it during the measurement. 

Thanks to the integrated data transmitter, the SOMNOscreen® HD plus always works wirelessly. This allows additional  remote signal control of the measured data: You get a screenshot of the measured data on your smartphone, tablet or computer. This way, you always know whether a patient’s home measurement is working properly, giving you peace of mind. 

We offer the first wireless EMG sensors for PLM conduction for additional patient comfort.

Unique Wireless Sensor Technology

The SOMNO HD™ is capable of accepting up to 6 wireless sensors – the first of these to be made available is the wireless PLM sensor package. More will follow in the future.

Why use a Wireless Sensor?

  • Time saving during application
  • More freedom of movement for the patients
  • Reduction of consumables and running costs (cables and connectors)

Details of the optional wireless PLM Sensors

  • Guaranteed measurement time of 10 hours
  • Outstanding signal quality
  • Continuous recording of the electrode impedance
  • Sampling rate adjustable between 64-512 Hz
  • Synchrony ≤ 60 ms
  • Automatic activation and start of the measurement by applying the sensor to legs and/or arms
  • Easy application with disposable electrodes (Ag/AgCl)
  • No additional costs due to environmentally friendly and rechargeable Li-Ion batteries

Docking station for simplified handling

The docking station is used to download the measurement data, charge the SOMNO HD™ Li-Ion battery and to install regular, free of charge firmware updates as long as you are connected to the internet. This means your SOMNO HD™ can be always up to date.

A virtual docking station also appears on your PC and shows the actual status of the device and the battery.

Of course, the SOMNO HD™, like the other SOMNOmedics devices, also offers real-time telemetric data transfer to the PC or tablet PC. In addition, the measurement data is saved on an internal memory and can be transferred at the end of the night via the docking station. So no measurement is lost.
