U.S. AutoFlow CO2 Incubator Series

The US AutoFlow NU-4750 offers laboratory technicians an incubator which virtually runs itself to dependably control the temperature and CO2 level. A solid-state single gas analyzer, with 32-bit digital accuracy, utilizes a filter correlation technique for non-dispersive infrared analysis of CO2. The measurement of CO2 is independent of humidity and temperature variations within the chamber

Features :
- Programmable Microcontroller Dependability
The US AutoFlow is run by a programmable microcontroller that samples input sensors, sets control outputs, makes corrections through the use of fuzzy logic, and displays status on the control panel. Ultra Smart ( US) " Fuzzy Logic" provides quick, accurate, adaptive control of all the incubators parameters: chamber temperature, CO2, O2, humidity and door temperature. Fuzzy logic tolerates environmental changes and component variation. It continually adjusts and improves to provide a " living" , exceptionally stable chamber environment.

- Relative Humidity Display and Control
The US AutoFlow NU-4850 has a relative humidity display and control system. The system controls from ambient to 95% relative humidity. The recovery time to 95% ± 2% is typically less than 10 minutes. The accuracy is ± 3% from any given set point.

HEPA Filtration System :
The US AutoFlow employs two separate capsule HEPA filters to minimize potential contamination problems within the chamber. After a door opening, the internal recirculation system will return the chamber to better than Class 100 air quality within 30 minutes.

Oxygen Display and Control :
The US AutoFlow NU-4950 has an O2 display and control system. The system controls from 21% [ ambient level] down to 2% . The recovery time from ambient to 5% ± 2% is typically less than 10 minutes. The accuracy is ± 1% from any given set point. The oxygen sensor is a fuel cell type and is unaffected by CO2, H2 or other various acidic gases.
