Mini CO2 Submersible pCO2 Sensor

The Mini CO2 instrument uses infrared detection to measure the partial pressure of CO2 gas dissolved in liquids. With pCO2 ranges from 0-1000 ppm up to 0-100%, the Mini CO2 provides the versatility needed for any application.

Mini CO2 submersible instruments are compact, lightweight, plug and play sensors. The instrument also measures total dissolved gas pressure (TDGP), a useful parameter for many applications and data correction.

With housing options rated to 6000 dbar of hydrostatic pressure, and resistance to most corrosive liquids, the Mini CO2 can provide reliable dissolved carbon dioxide data for many applications. Flow-through and in-line adapters are also available for simple and effective industrial solutions.

For specialized applications, Pro-Oceanus can provide custom solutions to suit any need.
