Capacity by Species
Approximate maximum capacities using the quadrants as supplied. All four mix-and-match quadrant sets are included, so you can run more eggs of one size or different sizes at once.
Built for Hatching Success
Humidity is one of the biggest causes of a disappointing hatch, particularly in the last few days. The EX removes that variable - an integral peristaltic pump holds humidity anywhere from 20% to 80% RH with a digital readout, drawing from an external reservoir so no standing water sits in the incubator. Combined with the mix and match quadrant system, all four sets of which are included, it suits breeders running valuable eggs and anyone hatching several species across the season.
Turning on the Maxi 48 EX is switched on and off manually, so remember to turn it off two days before hatching. Turning intervals go down to 5 minutes, which suits parrot eggs. If you would like the incubator to stop turning for you automatically, and to control the machine from your phone, see the Maxi 48 EX Connect.
