New Compact in situ pCO2 Sensor
By Marine Technology Reporter
Turner Designs now offers C-sense, a compact, lightweight pCO2 sensor for measuring the partial pressure of gas in liquids. Designed for applications involving immersion in water, oil, or water and oil mixtures, C-sense combines an oil-resistant membrane interface with a compact temperature-compensated nondispersive infrared (NDIR) detector.
Small (<2” x 8”; 5cm x 20.3cm) and lightweight (<1lb; 0.5 kg) with low power requirements (6-12V DC, 80mA at 6VDC) and a simple four-pin analog output, C-sense is designed to easily integrate with monitoring systems at a significantly lower price than traditional submersible pCO2 sensors. C-sense is offered in three range configurations – 1,000ppm, 2,000ppm or 4,000ppm with accuracies at 3% of full-scale and can be deployed to a depth of 600m.
C-sense was developed specifically for Turner Designs by Pro-Oceanus Systems Inc. in Nova Scotia, Canada. Pro-Oceanus has been providing the oceanographic research community with accurate submersible pCO2 sensors for more than eight years.
