AFT-CO2
AFT-CO2-0434a
  • Measures the partial pressure of CO2in water (pCO2- wet) from 150-700 μatm (other ranges available by request)
  • Based on the same technology as the SAMI-CO2
  • Packaged to be plumbed into a sample line on a research vessel
  • Once programmed and launched, the AFT-CO2 can run autonomously or while connected to a PC if real-time data is required
  • Logs own data
  • Can be configured to support other external instruments if required
  • Uses a highly accurate colorimetric reagent method
  • Calibrated against a NIST-traceable NDIR system
  • Accurate +/- 3 μatm
  • >Designed to provide researchers with valuable data during research cruises with minimal oversight.
