CO2 Measurements in Customized Set-Ups
Implantable CO2 Microsensor IMP-CDM1 (Prototype)
The implantable CO2 Microsensor IMP-CDM1 is not mounted into any additional housing and therefore ideally suited for implementation in customized applications. The bare glass fiber tip can be mounted to your own housing, steel tubes, catheters, etc. This tiny probe has a tip size of 250 µm and a maximum outer diameter of 900 µm. As the IMP-CDM1 is free of metal, it can be used in the presence of electromagnetic fields and even NMR environments.
- CO2 measurements in liquids (0.04 to 5 % CO2)
- High spatial resolution (250 µm)
- Ideal for physiological solutions
- Not influenced by electromagnetic fields
