PRODUCT SHEET ACCURATE AND FAST UNDERWATER pCO2 SENSOR Critical CO2 data captured on fixed and mobile platforms including ROVs and AUVs The CONTROS HydroC™ CO2 sensor is a unique and versatile underwater carbon dioxide sensor for in situ and online measurements of dissolved CO2. The CONTROS HydroC™ CO2 is designed to be used on different platforms with different deployment schemes providing complete flexibility for researchers seeking CO2 measurement data in diverse locations. INDIVIDUAL ‘IN-SITU’ CALIBRATION All sensors are individually calibrated in a water tank which simulates the average deployment temperature. Here, a sophisticated reference detector is used to verify the pCO2 concentrations in the calibration tank. The reference sensor is recalibrated with secondary high quality standards on a daily basis, which ensures that CONTROS HydroC™ pCO2 sensors achieve unmatched short and long term accuracy. OPERATING PRINCIPLE Dissolved CO2 molecules diffuse through the newly designed custom made thin film TOUGH 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 the sensor’s firmware and data from additional sensors within the gas circuit. A wide range of available accessories ensures that CONTROS HydroC™ CO2 sensors can be adapted to meet any requirements. Optional pumps with different flow heads enable very fast response times and an antifouling head can be specified for conditions with significant biofouling challenges. The internal data logger can be specified in conjunction with the sensor’s flexible power management features and the CONTROS HydroB® battery packs for long-term, unattended deployments. CONTROS DETECT® includes real time data visualization, setting of sensor parameters (e.g. measuring intervals, internal data logger settings, sleep mode function) and is supported by a mission planning tool and data download from the internal logger.
