SAMI-CO2 Ocean CO2 Sensor
- Measures the partial pressure of carbon dioxide pCO 2 in water from 200-600 μatm (ranges above 600 are available by request)
- Uses a highly precise and stable colorimetric reagent method
- Provide researchers with valuable in-situ time series data
- Depolyable to depths up to 600 meters
- Can be deployed in the ocean or in freshwater
- Long-term depolyments - can run for more than a year taking hourly measurements
- Can support up to 3 external instruments such as PAR, dissolved oxygen, chlorophyll fluorometer, or CTD
- Can support inductive modems or external loggers if required.
- Biofouling Package available for deployments in productive environments
