Cadwell vs. XLTEK vs. Nicolet vs. Teca: Comparing Used EMG/EEG Brands

Choosing a Used EMG/EEG System

If you're buying used electrodiagnostic equipment, the manufacturer and model matter almost as much as the price. Here's a look at the brands we carry.

Cadwell

Cadwell systems in our inventory range from the Sierra Wedge and Sierra Wave EMG/NCV/SSEP machines to the Easy II EEG system and the Easy III PSG (polysomnography) system. Cadwell remains an active manufacturer, which generally means better long-term parts and software support for their equipment compared to discontinued brands. Shop Cadwell equipment.

XLTEK (Natus)

XLTEK systems, including the 1002 and Neuromax 1000, are compact two-channel EMG/NCV/SSEP units - a common choice for smaller practices needing a portable system. XLTEK also produced EEG systems like the EEG-2006, a 32-channel system with photic stimulator. Shop XLTEK equipment.

Nicolet

The Nicolet Viking Quest is a full EMG/NCV/SSEP system with base unit, laptop, preamp, and stimulator - a well-established name in electrodiagnostics.

Teca

The Teca Synergy is a portable EMG/NCV/SSEP machine with a 2-channel headbox, commonly used where portability between exam rooms or facilities matters.

What to Check Regardless of Brand

  • Confirm what's included (preamp, stimulator, footswitch, case) - itemized, not just 'complete system'
  • Ask if the specific unit has been powered on and tested, not just 'this model typically works'
  • Get warranty terms in writing
  • Confirm any required software licensing transfers to you
