UltraPro S100 customer

A system improved. Easy to use.

  • Comprehensive system features built-in control panel with integrated speaker, electrical stimulator probe, amplifier, Natus Elite software and connectors for optional devices
  • Easy-to-use interface with fewer control panel buttons and colorcoded function keys — already familiar to VikingQuest users
  • Amplifiers allow electrodes to remain in place to accommodate the most common modalities including motor and sensory NCS, needle EMG and EPs
  • Programmable stimulator buttons for key function control at your fingertips
  • Triple-programmable footswitch for hands-free operation
  • Simple, three-cable setup to begin testing sooner

Trusted Software. Reliable Data.

  • Industry-leading Natus Elite software powered by Synergy/Viking, with full patient and protocol compatibility with existing Natus products
  • Simple, customizable workflows speed up common operations like rollback, roll forward and edit average to generate reports faster
  • Includes AANEM reference values, automatically selected based on patient age, height, gender and body mass index
  • 48 kHz sampling rate provides high-quality signal with high-definition resolution for saved data in routine motor, sensory nerve conduction studies and MUP analysis
  • LivePlay up to 960s for optimal uninterrupted recordings and convenient offline quantitative analysis
  • Enhanced with additional, automated testing capabilities and improved integration for greater accessibility and system security

Comfortable for Providers and Patients.

  • Available in two convenient form factors: a lightweight system to travel easily in roller case or mobile, cart-based system
  • Upgraded control panel allows care providers — and controls — to remain right at the patients’ side
  • Faster workflows and minimal repeat stimulation reduce time and discomfort of testing procedures

We could not find one feature we wanted that the UltraPro did not have.
