The illumination incubators have the refrigeration and the heating bidirectional thermoregulating system, the temperature controllable function, is scientific research and so on plant, biology, microorganism, heredity, virus, medicine, environmental protection, the Educational department essential bench-scale equipment, widely applies in low temperature constant temperature experiment, raise experiment, environmental testing and so on. its main feature: 1) the box body's thermal insulation material uses the polyamine ester on the spot foaming foam plastics, has the strong antijamming ability to external hot (cold) the source. 2) the cavity uses the engineering plastics formation craft manufacture, has the strong corrosion resistance ability. 3) entire glass type box gate convenience observation work cavity. 4) is the protection refrigeration compressor, the control wiring design has the power failure protection and 4 minute time delay functions. 5) the temperature automatic control, uses the LED monitor demonstration digit intuitively clear. 6) fixed time by unprogrammability when controls basis user to establish.
