Needle-type CO2 Microsensor NTH-CDM1 (Prototype)

Micro-invasive CO2 Monitoring

Needle-type CO2 Microsensor NTH-CDM1 (Prototype)

The NTH-CDM1 is designed for measuring in small volumes. The sensor is based on a silica fiber with 250 µm tip diameter, which enables integration into manifold small scale environments. With its protective syringe needle housing the NTH-CDM1 can easily penetrate tissue, septum rubber or packaging materials. After penetration, the sensor tip is extended for measurements.

  • CO2 measurement in liquids (0.04 to 5 % CO2)
  • High spatial resolution (250 µm)
  • Ideal for physiological solutions
  • Precise on-the-spot measurements
