Fiber Optic CO2 Meter
pCO2 mini
The pCO2 mini is a precise fiber optic CO2 meter with temperature compensation. It is used with sensors based on a 2 mm optical fiber. A PC is connected to run the user-friendly software. The pCO2 mini is additionally equipped with an analogue output and a trigger input. The compatible CO2 sensors of type CD1 are optimized for physiological solutions.
- For use with non-invasive CO2 sensors & sensor probes
- One calibration for a multitude of sensor spots
- Software included
Applications
PreSens CO2 Sensors as an Alternative to Off-line Sampling
PreSens CO2 sensors were evaluated for monitoring the cultivation cells in a 3-L bioreactor. The sensors show excellent long-term stability over a period of 10 days during cell cultivation of CHO cells with an initial seed density of 400,000 cells/mL. The readings of the PreSens CO2 sensor offer the possibility to continuously monitor the CO2 concentration between two off-line measurements.

Scientific: Carbon Dioxide Monitoring for Biological Applications
Increased CO2 uptake from the atmosphere caused by anthropogenic sources is believed to cause ocean acidification, with not yet foreseeable effects on marine life and ecosystem. Monitoring pCO2 in experimental set-ups simulating future levels of carbon dioxide can help to gain knowledge on the effects of ocean acidification on marine fauna. Besides the marine application, monitoring pCO2 also allows knowledge to be gained on land-based plant physiology. Monitoring pCO2 helps increasing yield during aquaculture of fish (fish farming) by providing convenient growth conditions. Excess carbon dioxide levels need to be monitored as this leads to hyperventilation of sea animals.
