SAMI-CO2
The SAMI-CO2 was designed for accurate, long term, low-power measurements of pCO2. By using a calibrated reagent response, the unit can collect data for up to a year on hourly intervals, using only its battery.
- Autonomous instrument – program your sample interval and duration and deploy.
- Measures the partial pressure of carbon dioxide (pCO2) in water from 200-1000 μatm (higher ranges available)
- Uses precise, stable colorimetric reagent method
- Provides valuable in-situ time series data
- Deployable up to 600 meters depth
- For use in marine or freshwater environments
- Long-term deployments – more than a year taking hourly measurements
- Supports up to 3 external instruments such as PAR, dissolved oxygen, or CTD
- Supports inductive modems or external loggers.
- Biofouling Package available for deployments in productive environments
An easy to use, reliable pCO2 instrument for your next deployment.
