The revolutionary NEBULA, technology can regulate humidity such that the target value is reached and maintained without causing large, unpleasant, and persistent temperature and humidity variations during incubation. In fact, the NEBULA, uses an ultrasonic generator to inject energy into the water through its continuous variable mechanism, creating minuscule droplets (fog effect). The droplets are transported to the incubator by the provided pipe. When the droplets come into touch with heat, they immediately evaporate, generating humidity that the incubator's fan then homogenizes. It is dependable and easy to use.
