Dissolved oxygen sensors
Our pO2 and combined parameter sensors that include pO2 component are mostly supplied in a 'bare' fibre optic format for invasive yet minimally traumatic tissue monitoring applications.
A suitable gauge needle or catheter (e.g. Angiocath) can be used to deliver the sensor to the tissue.
Also available are specialized needle-encased sensors offering greater physical robustness and/or larger tissue sampling areas/volumes.

BF/O
pO2-only sensor
Format: Single fibre-optic.
Applications: Virtually any tissue type; in vitro O2 monitoring; minimally invasive, rapid response times, MRI compatible.

Requires: OxyLite E or OxyLab pO2 E only.
Product code: BF/O/E
Tip diameter: ~280 μm
Cable length: 2 m

BF/OT
pO2/Temp sensor
Format: Single fibre-optic + thermocouple.
Applications: As BF/O where temperature fluctuations are expected; may not be MRI-compatible

Requires: OxyLite E or OxyLab pO2 E only.
Product code: BF/OT/E
Tip diameter: ~350 μm
Cable length: 2 m

NP/O
Needle-encased oxygen sensor
The unique, robust construction of this 23G needle-type sensor enables pO2 sensing via lateral ‘windows’ – i.e. away from the site of maximal tissue trauma. Oxygen detection occurs via 3 laterally arranged, precision cut regions approximately 3 mm distal from the sensor tip. Tissue sampling area/volume is approximately 3 times greater than for the bare-fibre sensors (BF/O).

Requires: OxyLite E or OxyLab pO2 E only.
Product code: NP/O/E
Tip diameter: ~630 µm / 23G
Cable length: 2 m
