Compact Optical CO2 Meter
CO2-1 SMA
This small CO2 meter fits in any measurement set-up. CO2-1 SMA is compatible with dipping probes, flow-through cells and non-invasive CO2 sensor spots of type CD1 (measurement range 1 - 25 % CO2). It has temperature compensation, so even in environments with changing temperatures precise CO2 measurements can be performed. This USB-powered CO2 meter is operated with the PreSens Measurement Studio 2 software, which enables simultaneous control of several devices and combination with PreSens O2 and pH meters, so measurement networks can be set up. With numerous features and additional pressure compensation, the software makes the CO2-1 SMA applicable in many applications. Optionally, the CO2-1 SMA can be expanded with 4 - 20 mA analog output (via a converter box).
- For use with non-invasive sensors, dipping probes & flow-through cells
- Compact & lightweight (only 128 g)
- USB-powered
- Controlled by PreSens Measurement Studio 2
- Integrated temperature and pressure compensation
- Optional 4 - 20 mA analog output
Applications
Perfusion Monitoring with Optical Sensors
Pre-calibrated CO2, pH and O2 flow-through cells can be integrated in perfusion systems and bypasses. This allows easy monitoring of process parameters in perfusion bioreactors. Typically, Luer connectors are used, though FTC sizes for higher or lesser flow rates are also available.
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.
