AFT-CO2
The Autonomous Flow Through Instrument CO2 (AFT-CO2) has the following characteristics:
- 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.
