Deymed Technological Advantages

Battery Operated Offering the highest signal quality possible and lasting months on a single charge, Deymed systems significantly reduce artifacts and outside noise by running 100% on batteries.
Intelligent Charging Deymed's new ultra-low capacitance induction charging keeps the batteries full when the system is not in use. This ensures the highest quality signal is possible with full battery operation during sensitive neurophysiology tests.
High Sample Rates Designed with Digital Signal Processor technology, Deymed systems can sample at very high sample rates while changing any parameter on the fly digitally. DSP offers numerous advantages over standard analog processing.
Optical Isolation Optical isolation greatly improves signal quality and patient safety. This feature combined with long-lasting battery operation, offers the best-in-class technology for neurophysiological recordings.
Click N' Go System Easily detach your system from the cart with a single click and be on-the-go with a laptop. You are no longer forced to choose between a hospital cart or a portable system. You can now have both in one.
