iWire-GA2: PEAKPRO Research Grade CO2 & O2 Gas Analyzer

The iWire-GA2, Research Grade, CO2 and O2 Gas Analyzer is easy-to-use, robust and adaptable to human, animal and plant applications. The iWire-GA2 plugs in the iWire port on an iWorx Recorder for recording, display and analysis of O2 and CO2 signals. In addition, the iWire-GA2 incorporates an input for a Temperature Sensor (TM-220) and a Polar(R) Heart Rate Receiver (PHRM-100 ).

The iWire-GA2 is suitable for recording and measuring:

  • Basal Metabolic Rate (BMR)
  • Resting Metabolic Rate (RMR)
  • Respiratory Exchange Ratio (RER)
  • Sedentary to light activity VO2 and VCO2
  • VO2 Max
