Tissue Vitality – OXYGEN measurement

OxyLite™ Pro  & OxyLite™ Pro XL Dissolved pO2 systems

Our third generation, multi-channel dissolved oxygen (pO2) and temperature monitors with touch-screen

  • Oxygen (pO2) & temperature monitor
  • In vivo & in vitro applications
  • Fully ‘plug and play’; no calibration procedures
  • 2 or 4-channel monitors
  • Enhanced productivity & features
  • Touch-screen display











The measurement of tissue oxygen tension (ptiO2provides a direct measurement of the balance between oxygen supply (by the blood) and metabolic oxygen consumption (by the tissue), i.e. a readout of oxygen availability at the cellular level.

This is in contrasts to spectroscopy (NIRS) techniques, which merely describe haemoglobin oxygenation status.

Our OxyLite™ oxygen monitors will be of interest therefore to life scientists wishing to directly and continuously measure dissolved oxygen in the normal physiological as well as hypoxic ranges, both in experimental in vivo models, or in any number of in vitro applications.


Applications for OxyLite and OxyLite Pro include:

  • Tumour angiogenesis and oxygenation
  • Vital organ oxygenation during transplantation and shock monitoring
  • Cerebral oxygen during stroke
  • Brain and spinal cord injury
  • Tissue flap and wound oxygenation
  • pO2 monitoring in the eye
  • Dissolved oxygen measurement in hypoxic cell culture, bioreactors etc.

Key Benefits

The easiest-to-use dissolved oxygen monitors in the world!

No calibration procedures, no sensor drift, no obligatory PC/software interface, integrated temperature compensation, oxygen partial pressure displayed in absolute units of mmHg: our world-renowned OxyLite™ oxygen monitors are simply the most user-friendly oxygen monitors available today, period!

Absolute units of dissolved oxygen

The fluorescence-based technique employed by our oxygen monitors provides an absolute measurement of dissolved oxygen in mmHg or kPa. In vivo this provides a direct readout of oxygen availability to cells and tissue, in contrast to blood oxygen saturation assessment (pulse oximetry), which merely describes the haemoglobin oxygenation status of blood.

Sensitivity and accuracy

Third-generation opto-electronics provide unmatched sensitivity, stability and accuracy in the physiologically relevant pO2 range (0 – 200 mmHg) and under conditions of hypoxia (0 – 15 mmHg).

No oxygen consumption

Zero oxygen consumption at the point of measurement, thus innately suitable for continuous and absolute oxygen sensing, even under conditions of extreme hypoxia.

Microchip sensors

‘EEPROM’ technology embedded within our purpose-designed connectors provides unsurpassed ease of use and user convenience by completely eliminating all calibration procedures. Simply ‘plug and go’!

Touch-screen display and interface

OxyLite™ Pro models feature a touch-sensitive, high-contrast, 140º viewing-angle screen, which displays real-time data in both digital and graphical (trace) formats, and provides access to instrument/user settings.

Built-in temperature compensation

Automatic temperature compensation of the pO2 measurement through optional, integrated temperature sensors.


Full support for both in vivo (tissue) pO2 applications AND measurement of dissolved oxygen in vitro (e.g. hypoxic cell culture, tissue constructs, bioreactors and more).

Minimally invasive for in vivo applications

Oxygen sensor diameters range from approximately 230 µm – 750 µm to suit a host of tissue monitoring applications and cause minimal tissue disruption in use.

MRI compatibility

Dedicated sensor types provide support and compatibility for magnetic resonance imaging (selected sensor types only).

Multi-channel productivity

The OxyLite™ Pro is available as a 2-channel model or, uniquely, as a 4-channel device (OxyLite™ Pro XL) capable of driving up to 4 sensors simultaneously. This provides the flexibility to suit all needs, including the simultaneous monitoring of oxygen from multiple tissue sites (e.g. comparison of pathological versus control tissue sites), or multiple in vitro samples.


The OxyLite™ Pro 2-channel model can be factory upgraded to the 4-channel model (OxyLite™ Pro XL).

Single-sensor multi-parameter monitoring

Our OxyLite™ oxygen monitors have been specifically developed for use our OxyFlo™ blood flow monitors. The combination of these two fibre optic measurement systems provides simultaneous tissue blood flow and oxygenation data from each ‘triple’ parameter combined sensor.

USB digital output

Our entire range of tissue monitoring devices now include a dedicated USB output that supports direct streaming of real-time recordings to a PC running the popular LabChart® Pro* charting software by ADInstruments. After installing a complimentary Add-on, LabChart will automatically identify the specific type and model of Oxford Optronix monitor and pre-load all the necessary configuration and channel settings, providing the ultimate in ‘plug and play’ convenience. For researchers wishing to make multi-parameter measurements, the Add-on supports multiple Oxford Optronix devices at the same time. Data acquisition and recording just got a whole lot easier!
LabChart Compatible
*LabChart version 8.0.4 or later required; PC/Windows only

Analogue outputs

Continuous data recording to PC or Mac platforms is also supported via standard analogue data outputs offering compatibility with third party data recording solutions.

2-year product warranty

Our monitors are now provided with a comprehensive 2-year manufacturer’s warranty, covering defects in material or in workmanship. An optional extended warranty package, providing a total of up to 6 years of ‘peace of mind’ cover, inclusive of preventative maintenance servicing is available at the time of purchase.
