Researcher, Imperial College National Heart and Lung Institute

Julian was fantastic, he patiently walked me through the steps for diagnosing issues with our syringe pump. We found it was a simple belt that was broken and he sent out a replacement part the same day.

Oxygen Detection

Oxygen Detection

Oxygen Detection for use with TBR1025 and TBR4100


These sensor incorporate WPI’s proprietary combination electrode technology whereby the oxygen-sensing element and separate reference electrode are encased within a single shielded sensor design. A gas-permeable polymer membrane is fitted over the end of the sleeve, which allows oxygen to pass while blocking liquids, ions and particulate matter.

Oxygen diffuses through the membrane. The voltage applied to the sensor is held at -0.7V when the monitoring device is on and the sensor is properly connected. The magnitude of the generated electrical current is determined by the rate of diffusion through the membrane. The rate is proportional to the partial pressure of oxygen outside the membrane. The current serves as a measure of the partial pressure of O2.
