Pro-Oceanus: CO2-Pro™ FT pCO2 Sensor

Designed for continuous benchtop monitoring of CO2 on ships and in laboratories.

The CO2-Pro™ FT instrument measures the partial pressure of CO2 gas dissolved in water using infrared detection. Standard ranges from 0-600 ppm up to 0 – 2,000 ppm, along with custom ranges, provide the full spectrum of pCO2 needed for accurate measurement of water CO2 levels.

Labelled FT for Flow-Through version of our flagship CO2-Pro™ instrument, the Pro™-FT can be used wherever a supply of flowing sample water is available, including shipboard flow-through systems and laboratory testing.

The small size of the CO2-Pro™ FT makes it versatile and easy to integrate into larger systems where space is a concern. When combined with our anti-fouling features and options, the instrument can perform in even the most biologically active waters for extended periods of time. An internal zeroing feature provides a stable long-term baseline to ensure accurate measurements.

The CO2-Pro™ FT is factory calibrated using WMO traceable standard gases. In addition, detector temperature stabilization and measurement of gas steam pressure and humidity provide an accurate and stable measurement of pCO2 in water.
