J&J C2+12 Channel Computerized System




The popular I-330-C2+, now has advanced Windows software and a fast USB interface! It’s 4 differential channels for EMG, ECG, EEG, and 8 channels for temperature, skin resistance, and respiration, provide power, flexibility and functionality for a multitude of customized uses. J&J Engineering’s new Windows software displays signals, provides feedback, collects data, prints reports, and exports database compatible files. Features include automatic testing of electrode impedance for connection quality, easy hookup with reusable gel free sensors, and fast channel sampling at 1024 SPS for high resolution spectral displays and precision filtering. Connects via USB to any 1 GHz (or faster) laptop or desktop running Windows XP or older Windows versions with current updates.

The I-330-C2’s 12 channel capability supports simultaneous monitoring of signals, such as:
  • 2-person monitoring for ECG, HRV, Respiration, Skin Resistance or Conductance, and Temperature
  • 4 EMG channels with spectral and raw signal displays, 4 Skin Resistance and Conductance, 4 Temperature
  • ECG, 2 EMG, 2 Respiration, 2 Skin Resistance, 2 Temperature
  • 1, 2, or 4 EEG channels, Respiration, SR, Temperature
