Handheld Oxygen Sensor
This device measures the oxygen concentration in gas mixtures and air as a percentage of a mixture.
This device is used to measure oxygen concentration as a percentage (%) if gas mixtures are used together with isoflurane or sevoflurane anesthesia. It gives the researcher the O2 concentration of any gas mixture.
Two or three gases might be used in gas anesthesia, mostly O2 and air, and sometimes N2O is also added. The gas mixture is made by using three gas flowmeters. Hyperoxic and hypoxic gas mixtures can be created.
The device can be easily built into the tubing between the gas flowmeters and the vaporizer. It also can be used without the vaporizer when hyperoxic or hypoxic gases are mixed and the amount of O2 should be displayed.
