C-sense probes are compact, lightweight sensors for measurement of the partial pressure of gas in liquids. Designed for applications involving immersion in water, oil, or water and oil mixtures, the sensors combine an oil-resistant interface with a compact, temperature-compensated non-dispersive infrared (NDIR) detector. Designed for integration, C-sense enables pCO2 monitoring at a significantly lower price than traditional pCO2 sensors.
Turner Designs offers the C-sense submersible sensor for measuring the partial pressure of CO2 in water, providing users with a way to estimate dissolved CO2 levels in water samples or systems. C-sense uses a sensitive membrane that allows CO2 gas to pass into a chamber where it is then accurately measured. The resulting value is output as a voltage from 0 – 5 volts, proportional to and representing an estimate of the amount of CO2 gas in the water sample analyzed. As a low power analog output instrument, C-sense can easily be integrated to any third party system, CTD or datalogger that accepts a 0 – 5 volt signal and provides 6 – 12 volt DC power.
