Experience Constant Contamination Control (C3) – NuAire’s US AutoFlow NU-4750 is a single chamber water-jacketed CO2 incubator. The US AutoFlow is run by a programmable microcontroller that samples input sensors, sets control outputs, make corrections through the use of fuzzy logic, and displays status on the control panel. “Fuzzy Logic” provides quick, accurate, adaptive control of all the incubators parameters: chamber temperature, CO2, and door temperature. Fuzzy Logic tolerates environmental changes and component variation. It continually adjusts and improves to provide a “living”, exceptionally stable chamber environment.
