The DH Autoflow provides the highest computer technology, precise temperature control and an accurate CO 2 gas control system. The microprocessor is user-friendly with status indicators, LED display of control parameters and a touch control keypad to permit efficient operator entry of data. The NuAire DH AutoFlow Incubator uses a microprocessor based, non-dispersive infrared CO 2 sensor. The amount of energy diffused to the detector is an exact logarithmic function of the CO 2 concentration in the gas between source and detector. The wavelengths used are absorbed by a filter in the CO 2 bandwidth making the measurements insensitive to other components, such as water vapor.
Advanced design provides a very stable drift-free output requiring less frequent calibration.
The sensor is within the chamber air plenum so very accurate CO 2 control is achieved. A HEPA filter surrounds the blower on the positive pressure side and continuously cleans the circulated chamber air within the incubator. The HEPA filter uniformly distributes and cleans the air within the chamber at a rate of one complete change per minute. Fast Recovery Time Temperatures recovery within the chamber is very quick. For frequent opening and closing of the door, the temperature recovers at a rate of 0.3 C per minute.
