Q-S207 EKG/EMG Sensor

Home Products Electrophysiology Q-S207 EKG/EMG Sensor

Qubit Systems’ surface Q-S207 Electrocardiogram/Electromyogram (EKG/EMG) Sensor measures voltage waveforms produced during the contraction of the heart (EKG) as well as during other muscle contraction (EMG).

The action potential during heart muscle contraction or other muscles’ contraction can be recorded by surface electrodes as electrical activity at skin surface. The electrical signal is recorded by C610 LabQuest Mini data interface and C901 Logger Pro software but other data interface with software can also be used to record 0-5 V analog signal.

  • Easy to use, safe, electrode based system for measurements of muscle contraction
  • Two setting available: EKG (heart muscle contraction) and EMG (contraction of other muscles)
  • Calculations of Heart Rate in software (optional)
  • Optional Data interface and software available
