CONTROS HydroC® CO₂ FT

Short Description:

CO₂ FT – CARBON DIOXIDE SENSOR FOR FLOW-TROUGH APPLICATIONS

The CONTROS HydroC® CO₂ FT is a unique surface water carbon dioxide partial pressure sensor designed for underway (FerryBox) and lab applications. Fields of application include ocean acidification research, climate studies, air-sea gas exchange, limnology, fresh water control, aquaculture/fish farming, carbon capture and storage – monitoring, measurement and verification (CCS-MMV).

INDIVIDUAL ‘IN-SITU’ CALIBRATION

All sensors are individually calibrated using a water tank which simulates the deployment temperature. A proven reference flow through system is used to verify the CO₂ partial pressures in the calibration tank. High quality standard gases are used to calibrate the reference system before and after every sensor calibration. This process ensures that the CONTROS HydroC® CO₂ sensors achieve excellent short and long term accuracy.

OPERATING PRINCIPLE

Water is pumped through the flow head of the CONTROS HydroC® CO₂ FT sensor. Dissolved gases diffuse through a custom made thin film composite membrane into the internal gas circuit leading to a detector chamber, where the partial pressure of CO₂ is determined by means of IR absorption spectrometry. Concentration dependent IR light intensities are converted into the output signal from calibration coefficients stored in firmware and data from additional sensors within the gas circuit.
