CO2 sensors for CCR units

20160112· Does anyone have any experience in adding a CO2 sensor to their CCR? Except for the new Hollis SCR, I''m not aware of any rigs that come with CO2 monitoring capability. With most of the accidents on rebreathers occurring from scrubber issues, I would think a CO2 alarm would be a good idea. Any thoughts. Sent from my iPad using Tapatalk

TECHNICAL NOTE : Dissolved CO2 and Units of Measurement

Dissolved carbon dioxide sensors often utilize equilibrator systems with semipermeable membranes in order to measure CO2 directly in the gas phase, most commonly using an infrared detector. As a result, these instruments normally report a “gas phase” concentration of CO2 that is in equilibrium with the surrounding liquid in which the sensor is immersed. The same equilibration dynamics ...
