PT2499 EXO TERRA Incubator – Black 38 X 37 X 46cm 25L – The Exo Terra Reptile Incubator uses thermoelectric technology which enables the device to cool and to heat. The temperature range is approximately 2? to 60? (36? to 140?). depending on the ambient room temperature. The temperature can be easily set using the digital control; and the bright-light LED display indicates the current incubation temperature. This cooling and heating combination is extremely useful in rapidiy changing environments and during hot summers. The Exo Tecra incubator prevents egg loss due to overheating by automatically switching into cooling mode until the set incubation temperature is reached. Humidity is provided by adding water to the slide-out tray in the bottom of the unit or by adding an extra (optional) container with water.
