The BlueInOne is a gas analyzer for CO2 and O2. The device can be installed directly in the exhaust flow of the bioprocess and measures the concentration of CO2 and O2 there in real-time. The BlueInOne automatically compensates any fluctuations of pressure and humidity in the system. The readings are therefore extremely accurate even under fluctuating measuring conditions. The BlueInOneseries is currently comprised of two different models, the BlueInOneFerm and the BlueInOneCell. The BlueInOneFerm is designed to analyze fermentation processes, while the BlueInOneCells is primarily designed for studying cell growth processes. The analyzers are, of course, also suitable for other applications.
