Provided herein are systems for continuously measuring oxygen and carbon dioxide gas levels inside a cell culture incubator, comprising an oxygen sensor that uses LED based fluorescence technology to determine the amount of oxygen in the surrounding atmosphere, a carbon dioxide sensor that uses LED based Non-dispersive Infra-Red (NDIR) technology to determine the amount of carbon dioxide in the surrounding atmosphere, and electronics to wirelessly monitor the output from the oxygen sensor and carbon dioxide sensor. Most preferably, the system can be placed inside a cell culture incubator, and sensor readings are pre-compensated for temperature, pressure, and humidity. Also provided herein are methods of using the same.

Modular oxygen monitor

Provided herein are gas mixing systems, comprising a gas inlet for receiving two or more gases and a mixing chamber with a static mixer for mixing the gases. Preferred mixing chambers further comprise a reduced pressure compartment downstream of the static mixer that is in fluid communication with the gas inlet. A gas outlet is in fluid communication with the mixing chamber, and one or more sensors are coupled to the reduced pressure compartment and are configured to continuously sense various parameters such as barometric pressure and the percentage of oxygen in the gas mixture moving through the mixing device. Most typically, the readings of the sensor are pre-compensated for temperature, pressure, and humidity. Also provided herein are methods for using the same.
