Turner Designs has introduced a submersible logger created to work with its C-sense pCO2 sensor. Designed by Precision Measurement Engineering, the C-sense Logger packages records, times, dates, internal temperatures, and partial pressures of gas in liquids. C-sense enables in-situ pCO2 monitoring over an extended period of time in water, oil, or water and oil mixtures in depths up to 600 m. Applications include water quality monitoring, aquaculture, wastewater monitoring, and more. Integration with the logger enables collection and internal storage of data at a variety of sampling rates, set by the customer. Data is offloaded to a computer via a USB cable.
