Surpass

EMS Biomedical

Advanced neurodiagnostic system for EMG, EP, and IOM - built for clinical precision and research innovation

The Surpass family by EMS Biomedical is a comprehensive 2 to 24 channel electrophysiology workstation for neurophysiological diagnostics, integrating electromyography (EMG), evoked potentials (EP), and intraoperative monitoring (IOM). Designed for both clinical environments and research laboratories, Surpass systems combine superior signal fidelity, versatile stimulation options, and a powerful, user-friendly software suite to meet the full spectrum of neurodiagnostic needs.

Surpass stands out for its signal quality, low noise architecture, and flexible amplifier configurations ranging from 2 to 24 channels. Whether you're performing routine nerve conduction studies or complex multimodal intraoperative monitoring, Surpass adapts to your workflow with ease. Systems can be configured as portable laptop units, desktop workstations, or fully-integrated cart-based labs, depending on the application.

With its broad range of stimulation modalities, including auditory (clicks, tones, speech), visual (LED goggles, checkerboard, pattern reversal), and electrical (up to 100 mA), the Surpass system supports a vast array of diagnostic and research protocols. Its intuitive interface, customizable acquisition templates, and MS Word-based reporting engine enable efficient data capture, review, and documentation.

The integrated 2-channel electrical stimulator and free programmable auditory stimulator provide comprehensive testing capabilities, while the touch panel control and cascade display of up to 99 traces ensure intuitive operation.

Trusted by neurophysiologists and neuropsychologists worldwide, the Surpass platform is built to evolve - making it an ideal long-term investment for clinics, hospitals, and research institutions seeking a reliable, scalable, and future-proof neurodiagnostic system.
