iWire PEAKPRO Research Grade Gas Analyser


SKU: iWire-GA2 Category:


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
