Oxygen sensors for OxyLite

A wide selection of oxygen sensors is available to suit both physiological (in vivo) monitoring and a variety of in vitro applications. Sensors featuring integrated thermocouples support automatic temperature-compensation of oxygen readings. Oxygen sensors are supplied in sealed Tyvek® pouches.

Bare-fibre oxygen sensors

• NX-BF/O/E Oxygen-only bare-fibre sensor

Flexible, minimally invasive sensor suitable for localized oxygen measurements from virtually any tissue type, or for in vitro dissolved oxygen applications.

Tissue placement via introducer (e.g. Angiocath®)
T-90 response time approx. 20 s
Manual temperature compensation required
Removable/adjustable Luer
MRI compatible

Dimensions:
Tip diameter: approx. 250 µm
Exposed tip fibre length: 6 cm
Total sensor length: 2.5 m

Reusability: Limited due to fragility

NOTE: THIS SENSOR TYPE IS ALSO AVAILABLE IN 8 M LENGTH FOR MRI APPLICATIONS

• NX-BF/OT/E Oxygen/Temperature bare-fibre sensor

Flexible, minimally invasive sensor suitable for localized combined oxygen/temperature measurements from virtually any tissue type, or for in vitro dissolved oxygen applications.
